Do you authenticate your customers before accepting their emails for
sending? If you do this, it should stop virus infected computers from
sending emails through your server.

Dear All,
We are running postfix mail server and open relay for our clients to
send mail out. We use amavisd-new and spamassassin to filter spam
mails before allow to send it out.
In some case the messages are spam but spamassassin can not detect
that so our clients spread the spam mails to the internet.
My idea is to solve the problem is to limit the number of mail send
in second for each customers, this is the correct way? or any advise
on this problem?
How to limit number of mail send in postfix / second for each customers?
Thank in advance for all advises.
