Plesk 9.2.3 Major Email Issues

[Eric Haskins]

I am seeing a ton of
Jan 11 12:32:08 srv1 greylist[6983]: SMTP: EHLO: 250 hello
Jan 11 12:32:09 srv1 greylist[6983]: SMTP: MAIL: 250 Mail from <hum525@domain.com>
Jan 11 12:32:10 srv1 greylist[6983]: SMTP: RCPT: 450 Rcpt to <tracy@blahblah.com> - Temporary local problem - I said try later
Jan 11 12:32:24 srv1 /var/qmail/bin/relaylock[6926]: /var/qmail/bin/relaylock: mail from 78.29.129.246:2236 (not defined)
Jan 11 12:32:24 srv1 greylist[6926]: IP 78.29.129.246 new - temp error

As I remember it can be caused by third-party utility which is invoked upon connecting to the server's SMTP service. Try to check following:

# grep greylist /etc/xinetd.d/smtp_psa

There can be something like /var/qmail/bin/greylist
Make sure that it is third-party, but not Plesk package with following command, for example:

# rpm -qf /var/qmail/bin/greylist
qgreylist-0.3-3.el4.art

If it so, just remove /var/qmail/bin/greylist from /etc/xinetd.d/smtp_psa.
It should help.
