dovecot - Dec 2007 - Problem downloading mail with "large" attachment using Thunderbird....

We have a user that is using Thunderbird on Windows to read mail over IMAP and
it works ok, except for downloading mail with
"large" attachment.. When opening a mail with a attachment with a size
of 14-15MB, TB downloads the attachment seemingly ok, but
TB stops when reaching 99%. After TB has stopped, if the user tries to select
another mail, TB just hangs and it has to be closed
and started again to work again...
I have checked the dovecot log, but I can't find anything there... We have
also tried to create a log in TB but everything looks
ok there also... 

Is there a known problem with TB and "large" attachment or does anyone
know how to fix this, if possible?


Regards,

BTJ

It happens to me too sometimes. The progress bar just runs to 99%
instantly, you just have to wait longer. Try downloading that attachment
with Outlook and see how much it takes.

And yes... it is a TB issue...

v1.0.8 fixed this for maildir, v1.0.9 for mbox.
