PROVIDED THAT YOU HAVE F-SECURE INSTALLED AND ENABLED, it is safe and arguably a best practice to exclude SPOOL and OUT directories from scanning. Especially OUT because the message has already been checked for viruses on the way it so why re-check the 10,000 outbound copies? But do NOT exclude TMP. On Windows and with default settings, this would disable the built-in security check!

I was referring to non-integrated scanning, particularly Symantec and similar products on Windows. I’ve seem SMTP handlers locked up when antivirus starts contending with spool files, etc. The right way to do that is with antivirus that hooks into the mail handler or uses a specific check directory but doesn’t seize up the whole works when an infected message comes through. If you have a scan-on-file-write antivirus doing a full scan of huge archive files each time a message comes in, it can (depending on the product and how it works) really mess the program attempting to do the writes. If you use the LISTSERV’s integrated F-Secure, this is not a problem, but non-LISTSERV-aware AV could cause issues. The same is true of inappropriate AV scanning of huge Exchange data store files and SQL database files. Yes, you need protection, but the wrong protection can be crippling.
