The POP3 mail is not getting through with build 5.0.167

This is my first trial with any Avast 5 beta (Version 5.0.167). Previously 4.8 worked fine.

When the mail shield is on, no mail is being fetched from the Compuserve provider imap.cs.com. All others such as http based mail is properly received. If suspending Avast for 10 minutes (great feature), mail is received into MS Windows Mail Live v 2008 (build 12.0.1606) on Vista 32 bit, SP1+all patches since. The mail is not mangled or anything since it it can be seen when logging in via webmail.

Ports set are #110 for income and port 25 for outgoing, the seeming defaults for Pop3 looking in the Redirect Settings area.

Any suggestions how to convince Avast to let mail through without compromising security?

thanks.

edit: oops, wrong forum, and see a topic there on mail which I will visit now.

Any error message ?
