IMP+scan4virus

[Roman Serbski]

Hello everybody!

Sorry for offtopic (maybe =)), but I hope someone here had experience with
implementing qmail-scanner (aka scan4virus -
http://qmail-scanner.sourceforge.net) with IMP?

I use Qmail 1.03, Vpopmail 4.9.7, scan4virus 0.94, Horde 1.2.4, IMP 2.2.4.
So, I edited imp/config/defaults.php3 file and changed sendmail to
qmail-inject:

// Where does sendmail live? We need this to send email.
$defaults->path_to_sendmail = '/var/qmail/bin/qmail-inject';

Everything works fine. Any incoming/outgoing messages are filtered by
scan4virus.
Now I would like to scan all outgoing (via IMP) messages.
As I see from message source, those messages which came through IMP were not
scanned by scan4virus.

Any hints?
Thank you.
Roman
