[Bug 620539] [NEW] From_ lines within the message body can confuse the archiver

[Axel Thimm]

Public bug reported:

This is on mailman 2.1.12 as shipped by Fedora 12.

The following From line in a message body caused the mail to have been
properly distributed, but was split in two in the archiving part:

=== Quote start
I think this would be a fairly common set up? Indeed I have three machines
that are setup this way (1 has 2 fans, the other 2 have 3 fans)

>From what I can see, pwmconfig does this:

pwm1_enable=0
pwm2_enable=0
=== Quote end

I'm not sure whether the From line was actually escaped or not when
mailman was processing it, as the copy I received went through exim
/dovecot-lda, and I think at least exim does fix unescaped From lines.

The mail above was split into the following in the mbox archives
(http://lists.lm-sensors.org/pipermail/lm-sensors/2010-August.txt.gz):

3 fans each)

Subject: No subject
Message-ID: <mailman.0.1281931669.3888.lm-sensors at lm-sensors.org>

pwm1_enable=3D0
pwm2_enable=3D0
=== Quote end

The html archives are truncated in a similar fashion.

I don't have the original mail, but I suspect that it was missing Lines
/Content-Length headers and therefore the possibly unescaped From line
was bogus. Still, if mailman was smart enough to ship the mail as a
whole it should be properly filing it into the archives as well. Also,
why is there an mbox splitting during archiving in the first place?

Thanks!
