Anti-virus overview

You can define separate anti-virus policies for inbound, outbound, and internal mail. See Inbound, outbound, and internal mail in the Key concepts section.

You can specify what action is to be taken when PureMessage for Microsoft Exchange encounters infected mail or mail that is encrypted (e.g. S/MIME or PGP encrypted message) or an encrypted attachment (e.g. password protected file). You can also specify exceptions from that rule, which have a policy of their own.

Click Configuration > Transport (SMTP) scanning policy and then click Anti-virus.

The screen displays types of event and the associated actions.

There are three types of events:

  • Infected mail which includes mail with a virus or other malware.
  • Encrypted message. Example, S/MIME or PGP encrypted.
  • Encrypted attachment. Example, a password protected file.

All events have the following actions: no action, delete message, quarantine message, quarantine message and deliver, and deliver message. The events On infection, and On encrypted attachment also have the action Replace attachment with text.

By default, anti-virus scanning for inbound, outbound, and internal mail is enabled. The menu bar for each direction of mail will be blue, and the associated icon will display a check mark and the word ON. If any menu bar is red, scanning for that direction of mail is disabled. Click the associated OFF text or circled alert icon to enable scanning.
