I have a problem with a postfix server. we are not recieving emails from many people and the error they are getting back is something like:
email@corp.com: host smtp.cop.com[1.1.1.1] said: 550 email@corp.com: Recipient address rejected: Mail appeared to be
SPAM or forged. Ask your Mail/DNS-administrator to correct HELO and DNS MX
settings or to get removed from DNSBLs; in rhsbl.ahbl.org (in reply to RCPT
TO comand)
I have read that rhsbl.ahbl.org is not working any more and therefore is returning false positives but I don't know how to remove that blacklist org from my server... We are missing lots of emails since 2 or 3 days ago. Could anyone give me a hand please?????
Thanks in advance & Best regards
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
OK, this doesn't look like a Postfix Admin problem - this list is for users of the Postfix Admin package rather than a generic Postfix support group. For general Postfix help, head over to postfix.org.
But, there are two places you need to look.
First of all, check your main.cf for "reject_rbl_client ..." lines - probably in the smtpd_recipient_restrictions section. I suspect this is where you'll find it, given that the rejection message is so specific.
The second place to look is if you are using any AV/Spam scanning setup (eg a ClamAV milter). ClamAV can use a variety of checks, you'll need to go through the config files for it to see what it's using.

thanks for your reply sorry for posting in the wrong place.
Even though this is unrelated to postfixadmin, STOP USING ahbl.org!
