Some clown out there has configured their system send DSNs to the from header instead of the envelope from, as required per the RFCs. I'm going to fire off a note to them later. Their DSN came from 'Mailer-Daemon <[EMAIL PROTECTED]>' and as of yet I have left LIKELY_BOUNCE_SENDERS with the default values. Whichs leads to my question, how did this message make it to the list? >From the post log I have the following Nov 03 04:26:53 2001 (962) post to list from [EMAIL PROTECTED], size=262, success >From Defaults.py LIKELY_BOUNCE_SENDERS = ('daemon', 'mailer-daemon', 'postmaster', 'orphanage', 'postoffice') Another question: Where might I find the code that deals with the subject prefix, the part that determines wether to add it or not? I've seen some posts to my list which have the prefix twice, appears that the client inserted a space at the beginning, i.e. ' Re: blah' instead of 'Re: blah' and mailman inserted the subject prefix, though it was already present.
