I too use multiple applications to provide security but I don’t feel it necessary to disable outbound scanning for the reason I gave in my last post and it isn’t about scanning inbound email but outbound email.

This function could provide an early warning of a trojan spambot installed on your system.

This perhaps wasn’t clear enough you/r system could be sending out spam that would otherwise not be detected. By having the Internet mail set to High and outbound email being scanned. This finds multiple identical emails in a short time, now these spam emails aren’t viruses or spyware but spam so they are unlikely to be detected by the other programs.

But it is your system and your choice.
