Hello,

I am running 1.0RC2 (upgrade from a beta, so I haven't tested RC1 unfortunately). I sometimes get empty messages in my inbox folder. Mails are stored using Maildir. Here is an output of a ls -la ~/Maildir/cur

-rw------- 1 n users 0 Jul 18 09:31 _CFC+Y5IvEB.gandalf.llorien.org:2, -rw------- 1 n users 0 Jul 18 09:28 _bEG+A2IvEB.gandalf.llorien.org:2, -rw------- 1 n users 0 Jul 18 09:54 _ezF+eOJvEB.gandalf.llorien.org:2, -rw------- 1 n users 2246 Jul 18 08:10 msg.f23:2,RSa

There is one real message (the last one). All messages seems to have strange file names names, even the real one. Messages delivered by the MTA generally have a name like 1152736772.H956194P17632.mail.llorien.org:2,RS

There is nothing in the SMTP server logs that could suggest these empty mails are delivered with SMTP and only dovecot version has changed. So I guess this is dovecot related. My IMAP client is thunderbird on Linux, but I have also seen the problem with sylpheed on OpenBSD.

Any help or hint appreciated.
