SpamAssassin Razor2 Notes (SME Server)

Sometimes logs include messages like:

razor2 check failed: razor2 had unknown error during get_server_info

Razor2 is a collaborative spam detection service used by SpamAssassin.

What it usually means

Most often:

• DNS trouble
• temporary network reachability issue
• Razor servers unreachable

It usually does not stop mail delivery.

Quick checks

DNS test:

dig +short a razor.cloudmark.com

Network reachability:

ping -c 2 8.8.8.8

Options

• Ignore if mail is working and spam filtering is acceptable
• Investigate DNS/network if you see lots of related errors
• Disable Razor2 if it is consistently failing and you do not need it

Note: Disabling spam checks may reduce filtering quality. Change conservatively.
