I was just playing with the Zimbra desktop client - at least in Linux,
it's a Java app that can do IMAP as well as zimbra, gmail etc.
When trying on my test account, it hangs while syncing.
It seems that it wants to download everything, not just subscribed
mailboxes. I have various unavoidable non-mailbox files like .procmailrc
and .vacation.db, but also some other cruft.
One of which is a broken mail file of some kind, another is a virus
sample, which cause imapd to bomb
As zdesktop won't run in plaintext mode I can't check the commands, but I
can reproduce the effect, viz.
$ imapd
1 list "" "h*"
* LIST (\NoInferiors \UnMarked) "/" head1
1 OK LIST completed
2 select head1
* 1 EXISTS
* BYE [ALERT] IMAP4rev1 server crashing: header size inconsistent
Aborted
syslog contains
Fatal error user=xx host=yy [a.b.c.d] mbx=/x/y/z/head1: header size
inconsistent
zdesktop reports this as
Failure communicating with remote server. Please try again later.
and can't get past this point
I was wondering why imapd does not merely return BAD to the SELECT
operation, and continue. Or is the thread too screwed up at that point to
safely do so ?
