I have an OpenBSD 3.5 machine ("membrane") running sendmail 8.12.11. I want all mail originating on that machine to be delivered to my mail host ("nucleus"), instead of being delivered locally. I can't figure out any way to make this happen; no matter what I try, mail to root still gets delivered into the local /var/mail/ without ever making an attempt to contact the mail host.
<LJ-CUT text=" --More--(11%) ">
Setting SMART_HOST has worked on every Linux machine I've used in the last decade, so I don't see why it won't work here.
(This machine sends almost no mail -- just the occasional cron job -- so I don't want to hear any crap about how great something-other-than-sendmail is. Don't make me ban you.)
So, in /etc/mail/aliases, I have:
root: jwz
jwz: jwz@nucleus.dnalounge.com
/etc/rc.conf says:
- sendmail_flags="-L sm-mta -C/etc/mail/localhost.cf -bd -q30m"
In /usr/share/sendmail/cf/openbsd-localhost.mc I have:
- define(`SMART_HOST',`nucleus.dnalounge.com')
which means that /usr/share/sendmail/cf/openbsd-localhost.cf, /etc/mail/localhost.cf, and /etc/mail/sendmail.cf all say:
- DSnucleus.dnalounge.com
I also tried adding "DHnucleus" to the .cf files. No luck.
There is nothing in /etc/mail/local-host-names.
(Yes, I have newaliased, HUPped, and even rebooted.)
Oddly, doing "Mail jwz@dnalounge.com" produces a bounce from localhost that says
- MX list for dnalounge.com. points back to membrane.dnalounge.com
which is just not true!
% dig dnalounge.com mx | grep MX
;dnalounge.com. IN MX
dnalounge.com. 3600 IN MX 5 nucleus.dnalounge.com.
(Note, that's "internal" DNS, you will see different results if you run that from where you are sitting right now.)
When I do this:
% date | Mail -vs test jwz

Note complete lack of any mention of nucleus. (I get the same result if I mail to "jwz@nucleus.dnalounge.com" instead of just "jwz".)
According to "host", membrane does realize that membrane and nucleus have different IP addresses.
Any ideas?
Update: Fixed! The answer is, put FEATURE(`msp', `nucleus.dnalounge.com') in submit.mc, and don't screw around with "smart_host" or "nullclient" at all. Thanks a lot to all those who helped.
