[pkg-fetchmail-maint] Bug#480851: fetchmail: fails to fetch some messages from gandi.net (dovecot)

[Christian T. Steigies]

Package: fetchmail
Version: 6.3.6-1etch1
Severity: normal

fetchmails fails to fetch some messages from my gandi.net mailbox, see the
log below for a message from the debian-kernel mailinglist:
Message-ID: <20080511230838.11224.90105.reportbug at xerces> 

This has happened for several mails that I received from debian and other
mailinglists. When I have one unfetchable message in my mailbox, fetchmail
can not retrieve any other mail from that server, unless I limit the size of
the messages to mails smaller than the stuck message, or I mark the message
as read through the webmailinterface, so that fetchmail skips this message.

This also happens with the lenny version of fetchmail:

fetchmail: Query status=2 (SOCKET)
fetchmail: normal termination, status 2

retchmail, however, has no problem downloading these messages.
