I'm using mailman 2.0.1 on a system with sendmail 8.9.3 (I know, I know, but I just don't have time right now to install exim :-/... this _HAS_ to be working by tomorrow evening, when I go on vacation--I'll look at it when I get back :). I'm using Everything is working fine, _except_ one thing: when I send mail to the mailing list, the To: field of the message I get back (as a member of the list) is incorrect and invalid. I send mail to "[EMAIL PROTECTED]", and when I get that message back it has a To: field like: To: [EMAIL PROTECTED] Now, here's the deal; this system was originally named "server". It still has this as /etc/hostname, and it still needs to respond to mail that way, etc. It also has a number of aliases, including lists.domain.com. I'm not sure where the "east" is coming from; the /etc/defaultdomain is "east" (but that's only used for NIS, right, so that wouldn't matter?), and the fully-qualified hostname of the server alias is "server.east.domain.com". Anyway, the question is why isn't the "To:" field using the lists.domain.com address? Who sets the To: field on outgoing (list) mail? Is it mailman? I can't find anywhere in mailman that might be using the "server.east" address. Or is it sendmail somehow? Is there anyone who knows enough about sendmail to point me in the right direction? I see lots of discussion of changing the From: address (masquerading), but not setting the "To:" address ?? -- ------------------------------------------------------------------------------- Paul D.
