Hello Roelof,

TBS>> I dont advise it.

Yes, I know.

TBS>> 1. Compress on exit checked in Inbox properties

As  you see, I advise USE the manual compression. 100%, again: 100% of
the  users have lost their mail in cases 1 or 2. None has lost emails,
because  they  did not compress mails. Believe me, they would complain
immediately.  I am sure, when closing TB there must be rare cases when
you  can  lose  mails.  And  I  have  contact  with a lot of users, so
statistically I see these things happen. If I see well so far, the bug
is  between  the  creation  of  the  new,  compressed  file  with some
temporary  name  and  the  deletion of the old, uncompressed TBB file.
That  is  why  I  wanted  to  take  a look at that code closely. But I
accept, Ritlabs does not want to show me that.

When  I will have time, I will setup a Bat on an other machine and run
some  batch that would start TB, import a mail to the Inbox, close the
program   with   Compress   at   exit  and  start  the  whole  routine
automatically.  If  I  observe  mail loss, I will do this on different
machines, maybe have some observation coming out of this experience.

RO> However,  we  were  discussing IMAP folders and I don't think that

Sorry,  I  should  have  mentioned,  that  I just wanted to write this
precaution  stuff  FYI, only. When I started to caution users for this
fact,  I  dont  have  complains anymore :))) I just wanted to share my
experience with the group.
