David,

sorry to disagree but the mouseover of the avast tray icon for email will never have anything to do with who an email is coming from or going to. It will only ever show the name of a server that avast is making an email connection to (either to receive email from that server or to send mail to that server).

To be clearer - if the mouseover ever shows the name of a server you have not deliberately selected in your mail client to send to or receive from then you are in trouble.

The only exception to this, as we have discussed before, is when you are using a P2P client connection to a server where you have been told to use a well known email port for the P2P connection.
