[Dovecot] mbox empty messages in Sent folder

[Diego Liziero]

I'm talking about mbox Sent folder, where some mailers append through
imap server
a copy of each message they send.

Sometimes, just three header lines got appended instead of the whole
mail message, such as:

>From xxxxxxxx at xxxxxx.xxxxxx.xxxxx.xx.xx  Fri May 23 12:30:14 2008
X-UID: 2852
Status: RO

This happened in the past (dovecot-1.1-beta/rc with Evolution and with
Thunderbird), and happened last week
with dovecot-1.1-rc5 (+ last week hg patches).

Anyone had a similar issue?

Regards,
Diego.
