Implementing Email Filtering: Strategies to Block Emails Containing Specific Links or Domains

[hdstockimages]

I am attempting to configure email filtering to block all emails containing specific links or domains in the body, but the setup remains ineffective. Here are the steps I’ve undertaken thus far:

1. Copied the configuration file:
   cp /etc/mail/spamassassin/custom.cf /etc/pmg/templates/custom.cf
2. Edited the configuration file:
   nano /etc/pmg/templates/custom.cf
   I included the following:
   plaintext
   Copy code
   uri __G_DRV /\\/drive\\.google\\.com/i
   uri __ONE_DRV /\\/onedrive\\.live\\.com/i
   meta CLOUD_SHARE (__G_DRV || __ONE_DRV)
   describe CLOUD_SHARE Suspicious cloud storage links
   score CLOUD_SHARE 1.0
3. Synchronized the configuration:
   pmgconfig sync --restart 1

Despite these adjustments, the filtering does not seem to function as intended. Any assistance in resolving this issue would be greatly appreciated.

I also didn't manage to get the custom.cf to work
