I have a Centos 7 server setup with Postfix, Spamassassin and procmail. It works fine, it receives and sends email , it passes it to the spam filter and delivers it to the required user or external email address.
The problem is, if I have a procmail recipe that processes mail, and then forwards it to an external address, this does not happen. On my previous Centos 6 server (with sendmail) this worked fine. The type of procmail recipe I am using is:
:0H * ^X-Spam-Score: * (\*\*\*\*\*\*\*\*\*\* /dev/null :0H * ^X-Spam-Score: * (\*\*\*\*\ $HOME/mail/Spam :0 !firstname.lastname@example.org
