[net.unix-wizards] Sendmail, the `m' flag, uucp, and rmail

arwhite@watmath.UUCP (Alex White) (03/13/84)

The configuration distributed with sendmail on 4.2 doesn't have the
`m' flag specified for uucp type mail.
In other words, generate one uucp mail message per userid, even if
going to the same site.
rmail on 4.2 accepts nicely multiple userids.
On v7, and on SV, rmail is a link to mail, which is quite willing
to accept multiple userids.

So, can anybody see any reason why the `m' flag shouldn't be specified
in sendmail?  (for mailling lists, this can mean a LOT less traffic,
especially if intermediate sites are also running sendmail with this
flag.

Is there anybody out there that knows an rmail this will break?

I can think of two problems with specifying the 'm' option for uucp
mail.  First, many mailers will insert a "To:" line if invoked with
more than one argument, which produces a completely mangled header.
Second, the limit on the length of a command line which can be passed
via uux is fairly small.  Exceeding the limit will produce undesire-
able effects such as core dumps from uuxqt.

The rmail on 4.1BSD systems only allows one recipient, so the sendmail
'm' flag will cause problems for mail sent to 4.1 sites.  Sigh.
