Re: [fetchmail-devel] Re: [fetchmail-users] Incorrect header line and lost mails

[Matthias A. <mat...@gm...>]

Greetings,

I think we'll shelve this problem and revisit in 6.4.X. I've thought
about it again, and there is no good solution. It is unclear whether
some mailer spoiled the blank line between header and body, and the
incorrect header line delimits header from body, or whether it's just
broken folding as observed by you.

I am very much in favor of Rob MacGregor's suggestion of putting the
message in a message/rfc822 container, and if user addresses have been
figured from the header, forward there, else to the fallback postmaster
(usually the calling user, literally "postmaster" if run as root, or
whichever is configured in the rcfile), and I'd be more comfortable if
such major changes can get testing first before being deployed. If it
works well, it might get backported to 6.3.X depending on how fast those
evolve.

I hope that's acceptable. If you want messages passed on in spite of
problematic headers, and let other parts of the mail system sort things
out, try the attached patch. It's highly experimental, may cause older
bugs to reappear that were masked (which please report, particularly
segfaults!), and isn't suitable for application in production or
distributions.

Regards,
