[imp] IMP with amavis

[David Brachet]

I have another question: when i send a mail from my local network, to a user
of my local network, with a virus, the message is detected as a virus (with
amavis / clamAV) and deleted. But when i do the same thing from imp to a
user of my local network, postfix doesn't seem to send the mail to amavis,
and the virus arrive to the recipient without checking. An idee from the
origin of this problem?

Thanks
