Re: mail relay
could you please explain me how do I configure spam-filter?
It's hard to say how to improve spam-filter in one/two sentences.
Just an example:
If you find some or most SPAM mails have subject "IREDMAIL", then you can filter it in either Postfix "header_checks or SpamAssassin.
In SpamAssassin, you can define your own filter rules in /etc/mail/spamassassin/local.cf (on RHEL/CentOS). Reference:
