BCC header false read as mail

Postby webservice » Wed Feb 15, 2012 1:34 pm

Running version: 2.1.1(11364)

After upgrade from 2.0.x one of our clients suddenly couldn't receive any mails anymore.
Reason was that a Exchange-server had a visible BCC-header in the mail. (I don't read in the RFC anything that it may not appear in the header)
So, assp blocked the mail falsely (the BCC-emailadres was not one of the recipients, and would not be sent to the BCC by us)

We changed $removeForeignBCC from 0 --> 1 in assp.pl, however assp should not read this header at all, why can't this header be threated as CC?

Feb-15-12 13:11:55 [RelayAttempt] <xxx_FROM_NON-LOCAL_xxx> to: yyy_LOCAL_yyy [spam found] ('relay attempt blocked for non local BCC recipient -xxx_BCC-NON-LOCAL_xxx ') -> /var/qmail/assp/discarded/3542.eml

The header of that mail:
