[exim] Null Message in client MUA

Hi all,


Some clients have problem with the mail downloaded from my EXIM server.

Those mails (in their MUAs) have the following characteristics:

1) empty subject and empty body. It has _nothing_ to show.

2) not exists in Maildir. i don't know where those mail comes from.

3) not shown in Webmail.


wonder if anybody experienced this problem before?

I'm running exim4.50 + MySQL + ClamAV + SA on sarge

Thx in advance.
