How can I stop Amavis from generating these messages?

Sounds as if you've enabled the "warnspamsender" (or maybe the
"warnsender_by_ccat") setting in amavisd-new. This setting is
off by default.
Sending any kind of sender notices about spam or virus is a
very bad idea because the sender is frequently forged.
Fix this in your amavisd.conf file, usually located in
/usr/local/etc/amavisd.conf
If you need more help, check the amavisd-new documentation,
search the amavis-users archives, or ask on the amavis-users
mail list.
