Hello
I`ve had problem for some weeks.
In my postfix logs:
| Quote: | Sep 10 00:05:30 mojhost postfix/error[29732]: 082545C90: to=<cpainter127418@comcast.net>, relay=none, delay=239948, delays=2
39945/3.4/0/0, dsn=4.0.0, status=deferred (delivery temporarily suspended: host mx2b.comcast.net[76.96.30.116] refused to talk
to me: 554 IMTA22.emeryville.ca.mail.comcast.net comcast MOJE_IP Comcast Blocked for spam. Please see http://help.comc
ast.net/content/faq/BL000000) |
I`m not open relay, I`ve all restrictions (I suppose) in main.cf.
I`ve spamassassin and amavisd-new too.
There is a many logs like above.
Am I spammer?
How can I protect my postfix?
Should I use mail signification procedure? DKIM?
I`ve no idea how could I stop those types of mail. |
