Okay,
I'd written the list before but the mess has evolved.
I installed postfix+dovcot on my server at linode, per instructions here:
http://library.linode.com/email/postfix/dovecot-mysql-debian-6-squeeze
and I'm having several issues.
when I telnet localhost 25 > ehlo localhost
I do not see 250-STARTTL
connections to the smtp server are refused (perhaps because of this?).
I see the following from tail /var/log/mail.err:
Jan 11 02:26:03 vulcan postfix/master[15403]: fatal: bind 0.0.0.0 port 25: Address already in use
Jan 11 11:30:30 vulcan postfix/master[16665]: fatal: bind 0.0.0.0 port 25: Address already in use
but according to lsof and netstat, as far as I can tell, the only thing using port 25 is the smtp server.
sudo lsof -i :25
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
sendmail- 10742 root 3u IPv4 14207 0t0 TCP localhost.localdomain:smtp (LISTEN)
I'm guessing your server has sendmail installed as well..
