Hello, i'm trying to stop some spammails with a header_check. The header_check looks for the hostname of our smtp-server in the "From:"-Line in the headers of incoming mail. I want to reject all Mails with this or similar "From:" Lines:
From: "DHL Team" m8148012...@itmu-smtp2.br.de<mailto:m8148012...@itmu-smtp2.br.de> Where "itmu-smtp2.br.de" is the hostname of our smtp-server. i use this header_check: /etc/postfix/header_checks: /^From: (?!.*\<root).*\@itmu\-smtp2\.br\.de\>/ REJECT seems to be spam, isn't it? /^From: .*\@.*/ WARN the first line should reject all spammails as described above, the second line should log all "From: " lines in the maillog with a warning from all mails, which passed the first line. What i see is, that the second line works as expected, the problem is the first line. None of the spammails with this or similar "From:"-Lines gets rejected and I see no message in the message-log. When i try local with telnet or a mailclient the header_check works as expected and the testmail gets rejected. I have no idea whats wrong, any ideas from you would appreciated. We use Postfix 2.11 on RHEL6 64bit.
