I am using sendmail as MTA, and I am looking for free anti virus.
About the milter, where can I download it?
Thank you

I don't think all of this is available via the the conventional centos
mirrors but I'd bet they're on Dag's as well as a few others. find one
you trust.
I am pasting the following from this website
http://www.be4mind.com/?q=node/190
I gave it a once over and it looks fairly complete. This write includes
adding greylisting as well.
PLEASE COPY CONFIGURATION FILE OPTIONS FROM THE ATTACHED DOCUMENT
(NEWLINES PROBLEMS IN HTML) OTHERWISE SOMETHING COULD GO WRONG
(EXPECIALLY WITH SENDMAIL).
