I think I may have figured this out but I'd like some advice before I
continue. Here's the current situation:

1) Mac OS X 10.3.9, with the postfix that comes preinstalled.
2) I am able to send mail to outside addresses. If I run

mail -s"whatever" minxmertzmomogmail.com < /etc/postfix/main.cf

I get the message normally.
3) But if I try to create an alias in /etc/alias, as in

matt: minxmertzmomogmail.com

then run newaliases and reload postfix, and then send to that alias:

mail -s"whatever" matt < /etc/postfix/main.cf

the message never arrives.

Here's what I noticed. In my /var/log/mail.log, I see

Jan 11 09:12:09 cca postfix/pickup[5259]: 845597F031: uid=1031 from=<matt_m>
Jan 11 09:12:09 cca postfix/cleanup[5260]: 845597F031:
message-id=<20060111141209.845597F031cca>
Jan 11 09:12:09 cca postfix/qmgr[5262]: 845597F031:
from=<matt_msteve.museum>, size=27302, nrcpt=1 (queue active)
Jan 11 09:12:09 cca postfix/smtp[5267]: 845597F031:
to=<mattsteve.museum>, orig_to=<matt>, relay=none, delay=0,
status=bounced (Name service error for name=steve.museum type=A: Host
found but no data record of requested type)

Key: the hostname is 'cca.' I'm logged in as "matt_m." It's the "to"
line that's interesting--postfix is trying to deliver the message to
'mattsteve.museum', even though 'matt' is aliased to
'minxmertzmomogmail.com.'

I guess the error message means that there is no MX record for
steve.museum. I didn't set up DNS, so that could easily be true. Is
that right; and could that also be why the alias never gets
interpreted? That is, does postfix try to deliver locally first,
before checking the alias?

Thanks,
Matt
