The problem with that solution is that you will have already got the virus into your mail folder and you face the risk of the whole mail folder being quarantined and that will be a big hassle.

With STunnel there is just one program to download and a bit of setup work that Norm321 has already worked out for you. That way all the smarts in the avast Internet Mail scanner can be used to prevent malware making into the mail file of Outlook Express in the first place.

Bert in Chicagoland,

I suspect that the future is going to look pretty limited for you since more and more mail services are moving to secured access. One driver of this is that more and more users are adopting wireless access and coming in from networks outside the control of the owners of the mail servers where the risk of snooping significantly increases. Just an example - one of the biggest players - GMail.
