Recently, I received a lot of virus email. I usually delete them. But a administrator send an email telling me my server send out virus email. I checked the email message, it seems some guys using a reply email address which host in my server to send out the virus email.
Is there any software to check virus in linux? How can I know if my mail got any problem?
Depending on the MTA(Mail Transport Agent) you are using, there are a variety of open source virus scanning solutions available. ClamAV(http://www.clamav.com) is one of the best, an it is constantly being updated with new definitions.
Unfortunately the newer viruses are forging the reply-to address as an address of another user on a completely different domain, when the e-mail is sent out from the infected computer.
I would not worry too much about receiving bounces claiming that a virus was sent from a domain you are currently hosting.
Hope this helps,
