header encoding issue causes qmail to choke
|
|
hello all,
I'm running net-qmail 1.06.
over the past few years I've seen situations where qmail will not process
emails where the "From" header contains special characters. I've been told
from a reliable source the the RFC's defining this (rfc2047 and rfc5322)
have been changed over time to include new encoding rules.
for instance an email containing the header:
From: "\"Firstname Lastname\"" <firstname.lastname [at] blah>
(Note that is only one example, it seems that any "special" characters will
cause this)
will cause qmail to not process this email correctly and it remains in the
queue. Eventually if enough of these pile up (happening more frequently)
qmail will crash.
finding the offending emails in the queue and editing them as such...
From: "Firstname Lastname" <firstname.lastname [at] blah>
then issueing a qmailctl flush command allows the email to process and
deliver just fine.
This is happening more and more lately, about once a week actually and I'd
like to know if there is any patch or solutions for this.

Thanks,
Jeff
