A massively important feature of most IMAP clients - leaving messages on the
server UNTIL/UNLESS they are deleted locally from the offline-copies - seems
completely unsupported by the mail client.

Typical reason for wanting to do this:

 - Usually use IMAP from home PC
 - When out of house (PC still at home, collecting email) I want to check my
inbox, and perhaps reply to some messages I saw earlier. Borrow friend's PC,
collect email locally, do my stuff, go home.
 - ...and carry on using my home PC.

I've gone through all the preferences and Mail/News preferences menus from the
Edit menu several times, and haven't been able to find anything relating to this.

Most IMAP gui clients (Outlook express, certainly, IIRC also Sylpheed and
various other X11 GUIs) have an extra checkbox for IMAP "Keep mail on server
when collecting email" or "Don't delete emails from server when collecting mail".

Often checking this box enables a further drop-down list of "Delete messages
from server when deleted locally"/"Delete messages more than XX days old from
server"/"Never delete messages from server".
WFM[20020710]. IMAP-files remain on the server until I delete them locally.

What is the build Id you are using?

To me it sounds like you want a POP mail option (which we currently have):
  "leave messages on sever" and 
  "Delete messages on server when they are deleted locally"

for Imap, which I don't think we will ever do.

Also this sounds like a request for enhancment rather than a bug.
And i think there maybe a similar bug/enhancement out there already.

Karen or David could answer better than me.

this sounds very confused - that option is for those clients when configured to
download messages with POP3, not IMAP. With IMAP, if you delete, you're saying
you want to delete it from the server.

Apologies; experimented further and found that the first comment was correct -
my IMAP server was moving the mails that had been collected by mozilla to a
different folder, and I misinterpreted the unexpected disappearance of all mails
as being deletion.

If the original bug report had been correct :) it would IMHO have been a bug,
but it was wrong, and IMAP mail is indeed remaining on the server as expected.
