You would like to exclude multiple email domains from being scanned for spam.
Sophos product and version
PureMessage for Microsoft Exchange 3.0 and above
What to do
- Create a .txt or .csv file containing a list of :
- ip addresses
- ip address ranges
- specific senders
Note: we recommend that you only add specific senders to this list (firstname.lastname@example.org); using a wildcard to add the entire domain (*@domain.com) increases your chance of receiving spam.
- Open PureMessage and click Configuration, Transport (SMTP) scanning policy, Anti-spam, Allow specific senders
- Import the text or csv file.
