dovecot - Nov 2010 - Problem with excel and word attachements ?

Hello

We are in (random) troubles with some emails that contains
word and excel attachements ( others attachements are OK )

I don't really think Dovecot is implied in this trouble but I want
to be sure ...

The problem is users cannot open attachements from their clients
( thunderbird 3.1 ) it stays in "download" mode until timeout.

Maybe there is a Dovecot's workaround to solve that boring problem ?

Thank you

last time i had that trouble with pdf it was a network problem with a
nic adapter on windows, try test with another imap client from another
computer on another network i.e some imap webmail client on the server
for verify
also check all relevant antivir solutions and/or proxies that may involved

hint, we dont allow *.doc directly as attach etc for security, such
stuff must
compressed , easy rule with postfix body check

There are known problems with Thunderbird 3.x and attachments. Many have
been solved with 3.1.x, but some still persist.

Setting the following prefs in user.js helps a lot:

user_pref("mail.imap.fetch_by_chunks", false);
user_pref("mail.server.default.fetch_by_chunks", false;
user_pref("mail.imap.mime_parts_on_demand", false);
user_pref("mail.server.default.parts_on_demand", false);

You'll need to restart Thunderbird then 'repair' the folder holding
the
affected messages (usually the Inbox) after setting these.

Don't think so...
