We are running WSS 3.0 SP2 on Windows Server 2003 R2 x64. We had recently upgraded our Sophos Endpoint Protection from version 9.7 to 10.0. Immediately, our alerts stopped working (although it wasn't noticed immediately). When you tried to create a new alert on a library the page would just hang once you pressed Ok. No workflows that used email would complete. (See http://community.sophos.com/t5/Sophos-Endpoint-Security-and/sophos-10-and-sharepoint-2007/td-p/20119) None of the fixes mentioned in that post worked for us, so we uninstalled Sophos 10 and reinstalled 9.7 which immediately allowed new alerts to flow.
My question is... are all of the alerts that were blocked by Sophos gone forever, or are they queued somewhere that we just need to kick some process to send? I've tried restarting the server, restarting the timer service, clearing the config cache... I'm not sure where else to look. Any tips appreciated!
EDIT: Workflow emails apparently did queue and send. Alerts did not though.
