One way to bypass spamassassin based on the envelope-sender (i.e. the return-path), is to use amavisd-new.
An interface between mailer (MTA) and one or more content checkers: virus scanners, and/or Mail::SpamAssassin Perl module. http://www.ijs.si/software/amavisd/ Thats my lines for real bypassing THIS list for spamassassin: /etc/amavisd.conf ### ENVELOPE SENDER WHITELISTING / BLACKLISTING - GLOBAL ### (RECIPIENT-INDEPENDENT) @whitelist_sender_maps = ( new_RE( ### ONE LINE --> qr'^users-return-[0-9] [EMAIL PROTECTED]'i, ### <-- ONE LINE qr'^...........$'i, qr'^.......... $'i, ), Don't use SENDER SOFT-WHITELISTING in amavisd because thats the same as in SA. It's only affect the score but don't bypass SA. Maybe someone helps this. On SuSE Linux amavisd-new can setup with Postfix in YAST. Ciao Marco.
