This causes problems on my company's mailserver, because connections aren't
claused correctly on the server (TIME_WAIT etc ...)

Current dump of netstat (build 2001110903, Windows NT, only showing relevant
tcp-connections) :

Proto  Local Address          Foreign Address        State
TCP    ktpc494:1048           bemail03.net.alcatel.be:143  ESTABLISHED
TCP    ktpc494:1232           bemail03.net.alcatel.be:143  CLOSE_WAIT
TCP    ktpc494:1233           bemail03.net.alcatel.be:143  CLOSE_WAIT
TCP    ktpc494:1234           bemail03.net.alcatel.be:143  CLOSE_WAIT
TCP    ktpc494:1268           bemail03.net.alcatel.be:143  CLOSE_WAIT

At this moment, there's no mail-window open, but there's still a connection to
the imap-server bemail03 for mail-checking (the first one). But the other ones ?
I've seen them in either ESTABLISHED state or CLOSE_WAIT state, but they're
*never* cleaned up. I know that the first one is used for biff-checking, becuase
there's traffic on them every 5 minutes. The others ones stayed like this for
over an hour.

Note that as a workaround, you can close the connections by clicking the
online/offline toggle in the right corner. This seems to really close the
connections, and they're put in a TIME_WAIT state.

I've also added a comment in bug 87825 , but that bug wants to remove all
connections when the mail-window is closed.

I am wondering to know whether you mean "quit for whole Mozilla or not"? 

Since BEFORE I close Mozilla from browser, I got:
 
carbuncle.143        h-10-169-108-247.nscp.aoltw.net.1925  8760      0  8760    
0 ESTABLISHED                                      

AFTER I close/exit Mozilla from the browser, it has been cleaned up. 
I don't know whether you are using different IMAP server as me or not? 
( I am connecting IMAP Messaging server)
Can you retest again or provide more info here? Thanks.

I'm not seeing the CLOSED_WAIT states anymore in build 2002072104 (Mozilla
1.1b). But we're not still sending the LOGOUT command.
