Hello,

I am running clam-av on postfix. When there was some problem with email
checking, I went to log file and found that the MESSAGE-ID of email in
question was changed as it got to clam-av.

How can I make postfix not to change MESSAGE-ID (the same way as sendmail
does not change it)?
In the logs below, the email had Message-ID 15BC014F1, and when checked by
spamd, got new ID 92C152443.
