Virus Scanners
Although the currently held belief is that Linux is immune to email viruses
targeted at Microsoft Outlook users, it certainly makes no sense for UNIX
mail servers to permit infected email to be sent through them. Although
Ubuntu does not provide a virus scanner by default, some of the popular
scanners are available in the Ubuntu repositories. Take a look at ClamAV as a
popular example.
Autoresponders
Autoresponders automatically generate replies to received messages; they are
commonly used to notify others that the recipient is out of the office.
Mercifully, Ubuntu does not include one by default, but you can find and
install an autoresponder like vacation or gnarwl from the Ubuntu
software repositories. If you are subscribed to a mailing list, be aware that
automatic responses from your account can be very annoying to others on the
list. Please unsubscribe from mail lists before you leave the office with your
autoresponder activated.
