I confirmed that if I kill this process (line from ps output):
qmaild 86243 0.0 0.1 904 360 ?? SNJ 3:05PM 0:00.09 tcpserver -v -H -R -lvps.breathsense.com -x /var/vpopmail/etc/tcp.smtp.cdb -c200 -u1003 -g1001 0 25 fixcrio /var/qmail/bin/qmail-smtpd
that incoming SMTP attempts are greeted by a 5.7.1 error.
Does anyone understand how this happens?
Thanks, Kurt Bigler
Well, considering that is your SMTP service, it looks like another server on the same system is taking over, or you configured something wrong.
since its freebsd, take a look at:
sockstat -4, and look for port 25 and what process has it in use if you kill that process you mentioned.
