Received Email events stopped working

[CJVann]

HS 2.2.0.76: About 2 weeks ago HS started to Error out when it checks for email. HS still sends email okay. Event is: Email received from anyone - speak. I made sure no other mail clients were running, and it still fails. The day before it quit, it started giving this error:

3/18/2008 1:13:39 AM ~!~Error~!~Unable to connect to POP server mail.comcast.net Error: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
3/18/2008 1:23:52 AM ~!~Error~!~Unable to connect to POP server mail.comcast.net Error: The requested name is valid, but no data of the requested type was found
3/18/2008 1:32:23 AM ~!~Error~!~Unable to connect to POP server mail.comcast.net Error: An existing connection was forcibly closed by the remote host


And since, has been giving this error:

Fixed!

I disabled McAfee SecurityCenter's "Inbound Email Scanning" and it's working now (Thanks Rupp!)
