Description Alexandre Oliva 2003-10-22 03:27:42 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031014

Description of problem:
Since the upgrade to -8, fetchmail started rejecting some e-mails that it used
to get perfectly well from a remote imap server.  It prints messages like this:

reading message aoliva@emilia.lsd.ic.unicamp.br:1 of 7 (2077 header octets)
..fetchmail: message delimiter found while scanning headers
 not flushed

and the message remains in the remote mailbox, while I get a message from
FETCHMAIL-DAEMON in my local mailbox.  This is a bad regressions.

The fetchmail configuration file says:

set daemon 900
set postmaster aoliva
set no bouncemail
   protocol imap
   auth ssh
   # mda "/usr/bin/procmail -d aoliva"
   to aoliva
   expunge 0
poll oliva@lsd
   via emilia.lsd.ic.unicamp.br.
   plugin "ssh -x -a -l oliva emilia bin/imapd"

imapd on the remote end is imap-2001a-18 (from Shrike).

I'll attach the contents of the remote mailbox after that fetchmail session was
completed, with the not-flushed message by itself.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.store the attached e-mail in your /var/spool/mail/box
2.set up fetchmail to do imap over ssh from there
3.run it

Actual Results:  the message isn't fetched.

Expected Results:  it should.  the previous release did.  fetchmail-6.2.0-3,
that I still have handy, does as well.

I have the same problem. This is related to the patch
fetchmail-6.2.0-reply_hack.patch. In my case the message is silently
flushed from the server despite the error. The problem is that linelen
is modified by reply_hack(), but its value is used elsewhere to
decrement a char counter in the mainloop. Does this patch work for you ?

Comment 3 Alexandre Oliva 2003-11-20 02:21:46 UTC
Thanks, I can confirm that the patch fixes the problem, apparently
without introducing any ill effects.

Comment 4 Fabrice Bellet 2003-12-11 15:21:46 UTC
Maybe an updated package could be released for Fedora Core 1 (as this
bug also applies to FC1) ?

Comment 5 Alexandre Oliva 2004-02-13 15:04:32 UTC
Any reason why this patch didn't make it even to FC2test1?

Comment 6 Alexandre Oliva 2004-02-24 13:40:14 UTC
Patch still applies cleanly atop of 6.2.0-10, and avoids the
unfetchable-message problem we've had since 6.2.0-8.  Could you please
oh please merge the patch in?  I've rolled my own RPMS to fix the
issue, and I could provide diffs to spec files if you'd like.

Now you don't have any excuse not to close this bug. ;)
