Thanks for the reply, first off. Just to make sure I was doing what I thought I was doing, I did the following experiments. I have a test box that delivers mail locally. If it thinks it shouldn't, for whatever reason, it sends the mail to the regular mail server and it delivers it. So, if I'm right, a "good" result is when it's delivered locally, and a "bad" result is when the mail gets shoved over to the regular channels. The variables are: relay_recipient_maps recipient_canonical_maps myorigin Now, my understanding is that myorigin applies when sending mail. It basically alters what the "from" address looks like to the ultimate recipient. With both relay_recipient_maps and recipient_canonical_maps defaulted, I sent mail like so: mail -s "gl bbb 12" g...@bbb.arlut.utexas.edu < /etc/motd bbb isn't a machine here. myorigin set to nothing -- postfix won't start. Makes sense. myorigin = crelm.toothpase -- postfix starts, the mail isn't delivered. Makes sense. myorigin = shoogams.$mydomain -- delivered via regular channel (bad), w/ from address of shoogams.$mydomain . The "from" address I expected. I was hoping it would be delivered locally, but my production machine wasn't doing that either, so if I have some other combination of things wrong, then... then I'm wrong. But this result is consistent w/ what I've seen before. myorigin = $mydomain -- the default, and what I've had in place on my production boxes all along -- delivered through regular channels (bad) but has the "from" address I want. So, eliminating myorigin as a variable. In the rest, here are the two non-default values of these variables. I had previously decided that relay_recipient_maps wasn't what I wanted, but some other things happened to make me wonder. So I tested it. relay_recipient_maps = regexp:/etc/postfix/pfrecipient_canonical recipient_canonical_maps=regexp:/etc/postfix/pfrecipient_canonical var/ value y= value above, def= defaulted rel... y def def y recip... def def y y myorigin $mydomain throughout result reg/bad bad good/locally To my eyes, this means myorigin does do good things when defaulted, but it doesn't do what I wanted/hoped. It appears to me that what I need is recipient_canonical_maps set to the value above in order to get what I want. Or am I missing something? Here's the postconf -n output of the test box. command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 html_directory = /opt/depot/postfix-2.8.4/html inet_interfaces = all inet_protocols = ipv4 local_recipient_maps = hash:/etc/postfix/users.here mail_owner = postfix mailbox_size_limit = 0 mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/local/man message_size_limit = 0 mydestination = $mydomain, davis.$mydomain, aaa.$mydomain mydomain = arlut.utexas.edu myhostname = davis.arlut.utexas.edu mynetworks = 127.0.0.0/8, 10.0.0.0/8 myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /opt/depot/postfix-2.8.4/README recipient_canonical_maps = regexp:/etc/postfix/pfrecipient_canonical recipient_delimiter = + relay_domains = vme.arlut.utexas.edu relay_recipient_maps = regexp:/etc/postfix/pfrecipient_canonical relayhost = vme.arlut.utexas.edu sample_directory = /etc/postfix sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_data_restrictions = reject_multi_recipient_bounce unknown_local_recipient_reject_code = 550 -- Jay Scott 512-835-3553 g...@arlut.utexas.edu Head of Sun Support, Sr. System Administrator Applied Research Labs, Computer Science Div.
