postgrey - postfix greylisting
I'm trying to figure out why postgrey is rejecting incoming mail...
From the syslog:
Sep 21 16:12:24 mail postfix/smtpd: connect from mail.ncf.ca[18.104.22.168]
Sep 21 16:12:24 mail dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth
Sep 21 16:12:24 mail dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so
Sep 21 16:12:24 mail dovecot: auth: Debug: auth client connected (pid=31224)
Sep 21 16:12:24 mail postfix/smtpd: Anonymous TLS connection established from mail.ncf.ca[22.214.171.124]: TLSv1 with cipher ADH-AES256-SHA (256/256 bits)
Sep 21 16:12:25 mail postgrey: action=greylist, reason=new, client_name=mail.ncf.ca, client_address=126.96.36.199, firstname.lastname@example.org, email@example.com
Sep 21 16:12:25 mail postfix/smtpd: NOQUEUE: reject: RCPT from mail.ncf.ca[188.8.131.52]: 450 4.2.0 <firstname.lastname@example.org>: Recipient address rejected: Greylisted, see http://postgrey.schweikert.ch/help/c...ryou.com.html; from=<email@example.com> to=<firstname.lastname@example.org> proto=ESMTP helo=<mail.ncf.ca>
Sep 21 16:12:25 mail postfix/smtpd: disconnect from mail.ncf.ca[184.108.40.206]
Any help greatly appreciated.
How interesting... so it's a temporary delay presumably because most spammers won't try several times. I wonder how long the delay is?
Default delay is 5 minutes. You can change it in /etc/default/postgrey
I lowered the default to 60 by adjusting hte POSTGREY_OPTS for debugging purposes.
Oh and the missing /etc/var/mail.log was an error on my part. I recreated it with the appropriate chmod switch and postfix is now writing to the mail.log as it should.
I am actually able to send mail out now from the domain to other addresses, and I know mail is arriving as it's shown in the log but, of course, I'm just not quite sure where to look for it... presumably somewhere via mysql.
I thought the "mail" command would show it to me but no such luck.
There is some more progress on the project and I thank you again for your input.
