Hello, I have a VAX running Ultrix 3.0 which is setup to be a "mail gateway" between the Internet and an internal network of Office Automation VAXen running VMS and All-in-1. To make it easy to get mail from an Internet site to a user on the OA net, I have a pseudo-domain defined so that an address can look like 'user@node.oa.uc.edu'. In sendmail, this type of address is intercepted and translated to 'node::mrgate::"a1::user"' and goes out over DECnet to the right machine. For OA mail that is bound for the Internet, I would like to change the 'From:' address to something that looks like Internet. (ie. I want to change 'node::mrgate::"a1::user"' to 'user@node.oa.uc.edu') This seems to be a problem, since '"a1::user"' is treated as a single token and there appears to be no way to get inside the quotes. Does anyone have any suggestions for getting around this problem? What I would really like is info on how to get inside the quotes, but I'm open to other suggestions as well. Thanks in advance for any help. -- Don Rainwater, Univ. of Cincinnati Computer Center rainwatr@ucunix.san.uc.edu rainwatr@ucbeh.san.uc.edu rainwatr@ucbeh.bitnet

You're correct, there is no way to get inside the double qoutes in sendmail short of having the source and fixing it yourself. That's not out of the question since 5.61 and IDA are both available but there is another alter- native (see below). > Does anyone have any suggestions for getting around this >problem? What I would really like is info on how to get inside the >quotes, but I'm open to other suggestions as well. Thanks in advance >for any help. The problem exists in sendmail. When a user on a VMS machine sends mail through a DECnet/Internet gateway and uses an address such as To: GATEWAY::"address-spec" sendmail doesn't strip off the double quotes. I had the same problem a while back and a kind person from DEC sent me a patched version that takes care of it. I'm willing to send out uuencoded versions to people who want it; if there is sufficient interest, I'll make it available for anonymous FTP. BTW, this was *supposed* to be fixed in 3.1 but apparently isn't so don't think that it will go away if you upgrade. -- Leonard J.

I'm not sure what I was thinking at the time but this is wrong. The problem is in /usr/etc/mail11dv3, *not* sendmail. I knew that when I posted before but I mistakenly said sendmail; it's been a while since I had to deal with it. Mondays are hell...... Anyway... /usr/etc/mail11dv3 is the actual culprit. And I do have a copy that works if anyone wants it. Everyone who asked for the patched version of sendmail will instead get a patched /usr/etc/mail11dv3. BTW, I also have a fixed version of sendmail if anyone wants it. It fixes a problem with having hosts first in /etc/svcorder and resolving outgoing mail to MX'd sites. I must have been thinking about this the other day. Sigh.... -- Leonard J.

Check out the DEC Ultrix Mail Connection if you want to hide All-in-1 users behind Internet addresses. It allows an Ultrix machine to talk directly to the message router on a VMS machine. We've been using it here now for about a year with some local modifications. Anything's better than trying to get sendmail to deal with quotes. I've tried and it isn't pleasant. -mark

There is not a good way to get inside of quoted strings. To sendmail's parser, a "quoted string" looks like a single token, which means that it will for example match $- and show up in $1 or whatever. This is a boon if you are trying to encapsulate a very-foriegn address in a way that guarantees that sendmail will leave it alone. It is a pain when you want to poke at the address. Standard sendmail has an "s" mailer flag that lets you strip off the quotes when you submit the message to an outgoing mailer. One thing you could do as a workaround is to submit to a mailer that just reinvoked sendmail in its A=; if you said M=s, the next round of sendmail process- ing would not see the quotes. This is a performance hog as well as very inelegant. I was running into this same problem on the DECWRL gateway recently, and my solution was to hack the sendmail source (which is freely available from Berkeley, UUNET, DECWRL, and a lot of other places). What I did was to notice, at the end of a given rule, that the address being rewritten had dwindled to a single argument and that that argument was a quoted string. In that event I strip off the quotes and re-tokenize the result. Since DECnet/mail11 insists on sending me things like DECWRL::"foo@baz", quotes and all, it fell to me only to strip off the DECWRL:: and my hacked sendmail binary pulled off the quotes automagically. Don't try this at home :-).. Paul Vixie DEC WRL -- Paul Vixie Work: vixie@decwrl.dec.com decwrl!vixie +1 415 853 6600 Play: paul@vixie.sf.ca.us vixie!paul +1 415 864 7013
