Mod.sources: Volume 3, Issue 68
Submitted by: Stan Barber <genrad!neuro1!sob>
This version of uumail contains all the fixes reported since
the last release. Thanks to those that reported problems and
especially those that sent along fixes or improvements.
This version also contains some improvements that I saw in
the GATech Sendmail Configuration version of uumail to help
uumail "know" when the database is being rebuilt. Please
be sure to read the README >ESPECIALLY IF YOU RUN A
DBM-formated database< ....
The next version of uumail will contain some more options
to allow header munging and path optimization (I hope).
If you already have some ideas or code that you'd like to
donate to the cause, send it along.
Have a good holiday, or if this comes out in 1986, Have
a good year.

This is an updated version of uumail (and uupath) that can
access a pathalias-generated database to facilitate routine mail.
These program can cope with DBM and standard line-oriented forms of
pathalias-generated databases.
This version of uumail can be used as uupath by linking uumail to
uupath. Also, this version can handle domain addresses (user@host.domain).
You can put as many addresses on a line as you like.
This version fixes a few bugs in the previous release. Some additional
functionality and robustness are added as well. The bugs included
lack of initilization of some variables in address.c, inconsistant calling
of getpath in uumail, address and opath, and failure to handle % in addresses
correctly. Additional features include the ability of getpath to detect when
the database is being updated and wait or abort as necessary, the ability to
retry accessing the database when it will not open (as might be the case when
updating it), the ability (if the database is sorted) to search a plain-text
database much faster.
* IF YOU ARE USING A DBM DATABASE, READ THIS!
* If the special sentinel value of @@@ is not present in the
* database, then getpath will assumed that the database is being
* rebuilt and will block for TIMEOUT (default = 180) seconds.
* If, after 5 such blocks, the sentinel is not present,
* the error code EX_TEMPFAIL is returned.
* The same is true if the dbm files cannot be initialized.
* Please be sure to add the sentinal to the DBM database when
* it is created.
*
There are some compile flags to be aware of when making uumail.
Here is a list of them.
DEBUG compiles in the debugging code.
OPATH causes the opath subroutine to be used to resolve addresses.
If you do not use this flag, you cannot use the user@host.domain style
addresses with uumail.
DBM causes uumail to use the DBM format patalias database. If you do not
have the dbm libraries, do not use this flag.
SYSIII will make adjustments for system that are derived from UNIX System
III or System V.
NOGRADE should be used if your uux does not understand the -g flag.
NORETURN should be used if your uux does not understand the -a flag.
LOG will enable logging of uumail traffic.
UGLYUUCP causes the From_ line produced by uumail to contain the
"remote from hostname" string.
GETHOSTNAME will cause the system call gethostname to be used. If you
are a BSD site, define this.
SYSTEMNAME will cause the systemname to be derived from the file
/usr/lib/uucp/SYSTEMNAME. This should be defined if your machine
is a Sperry 5000.
SORTED will cause the non-DBM database to be searched fasted, BUT
it assumes that this database is SORTED. If you do not sort your
database, do not define this.
If you want to install this system, use "make install". If you want
to have it do all the work for incoming mail, type "make mailer". You
probably do not want to "make mailer" if you run sendmail.
Here is the mailer segment of a sendmail configuration file that you
can use to define the uumail program as a mailer.

.TH ADDRESS 1 local
.SH NAME
address - display the path generated by \fBdeliver\fR for an
RFC822-format address.
.SH SYNOPSIS
address rfc-address [ ... ]
.SH DESCRIPTION
This program allows you to check the UUCP mail routing path that will
be generated by the UUCP mailer \fBdeliver\fR if you specify an
RFC822-format address \fBrfc-address\fR in the ``To:'' field of the mail header.
For each RFC-style address on the command line, \fBaddress\fR echoes the
address to the standard output, followed by a colon, followed by
the UUCP address that will be used to send the message to that address.
.SH "ADDRESS FORMAT"
Briefly, the RFC822-format address is of the form
.nf
.sp 1
<localaddress>@<hostname>.<network>
.sp 1
.fi
where <hostname> is the name of the system you are sending the message
to, <network> is a modifier for <hostname> identifying the network in
which the address is to be interpreted (UUCP, ARPA, MAILNET, CSNET, etc);
and <localaddress> is an address string to be interpreted on the host
machine.
The <localaddress> field may contain further remote addresses to be
interpreted on the host machine. Typically this will be an address for
mailing via another network; and in particular, the <localaddress> may
(recursively) be identical in format to the RFC address, but with
the symbol `%' replacing the symbol `@' in the standard address format.
Where this form is used, the rightmost % is replaced by an
@ before the host machine sends the message out.
On our system, the presently
valid <network>s are UUCP, ARPA, CSNET, and MAILNET.
The recently proposed UUCP domain names are also accepted, although
they are treated the same as plain ``UUCP''.
Omitting
the <network> causes the network to default to UUCP. The <hostname>
should be the name of a remote machine to which the message is
directed; see \fI/usr/lib/uucp/uuaddress.alpha\fR for a list of all
known UUCP hostnames. It is \fInot\fR necessary to specify a UUCP pathname
when using this format; the pathname is automatically determined for you
and substituted into the address before mailing. The selected pathname
is determined using the \fBpathalias\fR database, and is supposed
to be optimal, taking into consideration information provided by
each site about how often they send mail out, etc.
.SH EXAMPLES
.HP 5
joe
.br
The message is sent to the user ``joe'' on the local system.
.HP 5
joe@ucbvax
.br
The message is sent to joe on the UUCP system named ``ucbvax''; this
address is automatically translated to a proper (and ostensibly
optimal) UUCP path.
.HP 5
joe@ucbvax.UUCP
.br
Same as joe@ucbvax
.HP 5
joe@ucbvax.ARPA
.br
The message is addressed to joe at ucbvax, using the ARPA network.
The message will be routed to the ARPAnet via a UUCP-ARPAnet gateway.
.HP 5
joe%mit-multics.ARPA@ucbvax
.br
The message is sent to ucbvax, who then uses the address
joe@mit-multics.ARPA to send the message on to mit-multics via the
ARPAnet. Since ucbvax is on the arpanet, this address will work correctly
(as long as there is someone named joe on the MIT multics machine).
.HP 5
joe%vanderbilt.MAILNET%mit-multics.ARPA@ucbvax
.br
The message is sent via UUCP to ucbvax, who then sends the message
to mit-multics via the arpanet; mit-multics then sends the message
to joe@vanderbilt via MAILNET. Since the above machines each have access
to the networks named in the address, this address will work correctly.

.TH OPATH 3 "CONCURRENT"
.SH NAME
opath - Generate a UUCP route from an RFC822 address
.br
oupath - Generate a UUCP route from a (possibly disconnected) UUCP path
.SH SYNOPSIS
char *opath(s)
.br
char *s;
.sp 1
char *oupath(s)
.br
char *s;
.SH DESCRIPTION
These routines use the \fBpathalias\fR database to generate UUCP routing
paths from your local site to specified remote sites on either the UUCP
network or other connected networks.
.PP
\fBopath\fR takes one argument, an RFC822 address, as described in
ADDRESS(1). From this, it generates and returns a UUCP path to the site
named in the argument.
.PP
\fBoupath\fR takes one argument, a UUCP path. If the next site on this
path is named \fIx\fR, \fBoupath\fR will prepend a path from your site to
\fIx\fR, if \fIx\fR is nonadjacent to your site. If \fIx\fR is a domain,
i.e. contains a dot (.), \fBoupath\fR will generate a path to a gateway
for this domain. Note that \fBoupath\fR will \fInot\fR alter the argument
path, other than to make the above transformations; it does not check whether
sites in the argument are adjacent to one another, or whether they represent
an optimal path; it is assumed that if the user has specified a path, then
he wants to use that path.
.PP
The principal difference between \fBopath\fR and \fBoupath\fR is that the
former gives precedence to ``@'', whereas the latter gives precedence
to ``!''. The former is intended to be invoked when receiving mail from
a user interface or a non-UUCP source (if the subsequent transport mechanism
is to be UUCP), whereas the latter is intended solely to be used by UUCP
internal software, principally \fBrmail\fR, in routing mail through the
UUCP network.
.SH "FILES"
\fI/usr/lib/uucp/palias\fR - The pathalias database.
See PATHALIAS(1) for information; pathalias is a public-domain program
distributed via the Usenet's net.sources facility.
.br
.sp 1
\fI/usr/lib/uucp/domains\fR - The domain/gateway table. Each line of this
file consists of either a ``#'' followed by arbitrary comment text, or
an entry of the form:
.br
.in 1i
<domain>,<path>,<reserved>,<template>
.br
.in
Where <domain> is the string (in capital letters) identifying a particular
<path> is a string which may be included at an arbitrary point in the
generated route, <reserved> is currently unused, and <template> is a string
indicating the format of the generated route.
.PP
The <template> is a printf-style string; it is \fBnot\fR quoted, and
begins at the character immediately following the comma which separates
<template> from <reserved>. The <template> may consist of arbitrary ASCII
characters, which are copied unchanged into the generated route; or of
a percent (%) sign followed by one of the following characters:
.IP P
The <path> string is inserted. The <path> may consist either of a string
which is inserted unchanged; or of the character ``>'' followed by the
name of a UUCP site, in which case the entire <path> string is replaced
with a string representing the path to the named site. The last token on
this string is the site named in the original <path> string, without a
following ``!''.
.IP U
The user name from the original address is inserted.
.IP N
The site name from the original address, with the domain specifiers
removed, is inserted.
.IP D
The site name from the original address, including the domain specifiers,
is inserted.
.IP R
The UUCP path to the site named in the original address is looked up in
the pathalias database and inserted. Note that this path is looked up
only when the %R is seen while scanning the <template>, so an error message
for an invalid site name is generated if and only if it appears in an
address with a domain which contains a %R in its template.
.PP
When making entries in the domain table, domain names which are a suffix of
another domain name in the table should be ordered such that the longer
string(s) appear first. For example, .WA.UUCP should preceed .UUCP in
the table. A linear search is made of the table, and the first domain
found in the table which is a suffix of the domain in the designated address
is used as the domain in generating the routing.
.PP
Following are some example entries for the domain table. Note that all
domain names begin with a ``.''.

.SH "NOTE"
The <reserved> field in the domain table currently has a function which
may be determined by examining the source code for opath. However, this
function is a vestigal function provided for sites that used an earlier
version of opath; future opath versions will use this field for a different
purpose, and new users of opath therefore should \fBnot\fR use this field.

.B uumail [ \fIoptions\fR ] \fIaddress\fR
.br
.B uupath \fIhostname\fR
.SH DESCRIPTION
.B Uumail
is designed to be used as a mail delivery program to correctly
route mail over uucp connections.
.SS Standard Options
.IP "-f\fIaddress\fR" 16
The -f option sets the address of the sender of the mail. If this flag
is not used, the sender will be established by usings environmental variables
(like
.B LOGNAME
and
.B USER
) or using getlogin(3).
.IP "-m" 16
The -m option causes the mail to also be sent to the sender of the message.
.IP "-c" 16
The -c option causes
.B uucico
to be started immediately after queuing the mail.
The default just queues the mail.
.IP "-h" 16
The -h option causes no From_ line to be added to the beginning of file.
This is useful when uumail is being used as a mailer for sendmail(8).
.SS Compile-time Configurable Options
.IP "-d[1-6]" 16
The -d option turns on the limited debugging facility built into the
mailer. In debug mode, the mailer does not actually mail anything, but
tells you what it would do if it did do it. The level of debugging can
be set by following the
.I -d
flag with a number between 1 and 6.
.IP "-g[A-Z]" 16
If your
.B uux(1)
supports grading of transactions, the -g option can be used to set the
grade of this mail. A grade of \fIC\fR is used by default.
.SS Arguments
.IP \fIhost!user\fR 16
where host is a system node name on the network and user is the login
name of the addressee.
.IP \fIuser@host.domain\fR
same as above with the addition of a domain specifier like
.B .ARPA, .GOV, .COM, .EDU
etc.
.SH FILES
.IP "/usr/lib/uucp/palias" 20
Path file produced by pathalias.
.IP "/usr/lib/uucp/uucp/domains" 20
Domain rewriting rules for opath(3).
.IP "/usr/adm/uumail.log" 20
Log of uumail activity.

/*
* U U M A I L
* This program when invoked in the form:
* uumail host!user will consult the local usemap for
* the proper routing.
*
* If it finds it, it will invoke the proper uux call
* to send the mail.
* Otherwise it aborts with an error 68 (host unknown)
* $Log: uumail.c,v $
* Revision 2.9 85/12/10 20:36:01 sob
* Added new return flag from getpath EX_TEMPFAIL to signal that the
* path database is currently being updated.
*
* Revision 2.8 85/12/02 16:51:39 sob
* Added a fix to cope with percents in addresses returned by opath.
* Thank to steve@umd-cs.UUCP for the bug report.
*
* Revision 2.7 85/11/18 12:36:48 sob
* Added the -h option to cause uumail NOT to add a From_ line.
*
* Revision 2.6 85/11/14 20:20:06 sob
* Added #ifdef DEBUG to allow compiliation with out DEBUG installed
*
* Revision 2.5 85/11/14 20:14:11 sob
* Another little buggie in the log format...sheesh.
*
* Revision 2.4 85/11/13 15:53:18 sob
* Reformated the log file a little bit.
*
* Revision 2.3 85/11/08 03:03:51 sob
* This is the release version.
*
*
* Revision 2.2 85/09/30 02:51:18 sob
* This version uses opath when defined during compile time.
* With a bit of cleaning up, this is a release version.
*
* Revision 2.1 85/09/30 02:46:06 sob
* *** empty log message ***
*
* Revision 2.0 85/09/09 18:22:56 UUCP
* *** empty log message ***
*
* Revision 2.0 85/09/09 18:22:56 UUCP
* Added flags to conform with sendmail. Also updated the flags it could send
* to uux to conform with 4.3 uux command.
* Will add name resolution and header checking.
* Also will allow multiple addresses per line.
*
* Revision 1.7 85/08/03 00:49:14 UUCP
* Cleaned up with lint.
* Stan Barber
*
* Revision 1.6 85/07/11 19:30:00 sob
* changed PATHSIZE to PATHSIZ to conform with uupath
*
* Revision 1.5 85/07/11 18:08:13 sob
* This one works both as uumail and uupath!
* Stan
*
* Revision 1.4 85/07/10 18:35:05 sob
* moved DBM to getpath
* Stan Barber
*
* Revision 1.3 85/07/09 01:28:14 sob
* First attempt to integrate uupath
* Not successful. Changed PATHALIAS define
* to DBM... will ultimately alter getpath as well
* added gethostname call to fill in for local host.
*
* Revision 1.2 85/07/08 05:29:16 sob
* This one works with pathalias database...
* need to modify to substitue for uupath.
* Stan
*
* Revision 1.1 85/07/08 03:11:10 sob
* Initial revision
