Very annoying IMAP problem (cyrus + Outlook)

#1 08-22-2008, 05:01 AM

Hello,

We have 50 people using Outlook on our IMAP cyrus server. It's
wonderful : fast, efficient, no problem, easy...

But for 4-5 days I have a strange problem only on one PC :
* Outlook has to reconnect to the server every 5 minutes because of
"Fatal error: word too long".

As far as I understand, the cause of the problem is :
* "Outlook is sending either a token or quoted string that is longer
than 8K bytes."

But how could I correct this problem either in Outlook or cyrus ???
* Can I simply delete the "offending" email in Outlook, but how to
find which one ?

Thanks a lot in advance for your help !

1) Break into Microsoft's corporate headquarters

2) Steal the source code for Outlook

3) Find the bug

4) Fix it

5) Install the fixed version of Outlook on your machines

Hope that helps.

Look at the IMAP traffic (e.g. with Wireshark or ngrep) and see what
command it is that causes the error. If you're using SSL you'll have to
disable it temporarily to see the traffic (or find a program that can
look inside SSL connections with the server's private SSL key).
