Check /var/log/maillog, it's very possible that some user's password was cracked and used to send spams.

Hi Zhang,

Thank you for reply.

Already checked the infected emails and changed the password at the same stopped queued emails.

Any other suggestion how to fix this issue and avoid in the future?
