I have a mail system on Postfix+dovecot+amavisd+spamassassin+clamav. Now there is a task, an easy one, actually, but I still cannot find a solution. I need to change headers in emails according to several rules. For example,
IF (<TO> CONTAINS 'ALIAS_1' AND <TO> CONTAINS 'SOMEONE FROM ALIAS_1') OR (IF <TO>='ALIAS_1' AND <CC> CONTAINS 'SOMEONE FROM ALIAS_1') THEN (DELETE 'THIS SOMEONE FROM ALIAS_1' FROM <TO> AND DELIVER TO OTHERS) or IF <FROM>=ANYBODY_FROM_ALIAS_1 AND <TO>=ALIAS_1 THEN DELETE 'ONE_EMAIL_ADDRESS_FROM_ALIAS_1' FROM <TO> AND DELIVER TO OTHERS. or if such requirements could not be met at least some tool would be nice that can add another TO_header or remove some for some conditions. For example in EXIM MTA it can be done with exim.filter, smth like: if FROM contains A then deliver to B,C,D and so on. I have lurked through <http://www.postfix.org/addon.html> http://www.postfix.org/addon.html but could not find anything useful there. Header_checks internal feature of Postfix has limitations that make it useless in my case, IMHO. Any help would be most appreciated!
