SpamAssassin Network Ports

Question / Problem

Do I need to open any additional ports for the integrated SpamAssassin?

Answer / Solution

In case the required ports are not open, SpamAssassin scans will take much more time - which may cause a timeout.

The integrated SpamAssassin uses DNS (target port 53, TCP and UDP) for blacklist (RBL) requests. You also need to allow requests to target port 2703 (TCP) for Razor2. Otherwise spam scans may last longer than a minute. Alternatively, you may disable Razor2:
- Create a CF file like "XMySettings.cf" (text files) and put "score RAZOR2_CHECK 0" in it.
- Put this file in "C:\ProgramData\JAM Software\spamdService\sa-config\"
