I am with White-Note, reply #44
Fresh 10.8.2 and Office2011, using Outlook. My mail server does NOT use SSL, and the shield was already active in Avast, yet I got these annoying pop-ups. So I disabled the shield in Avast, and within seconds I received all mails that were queued up in the mail server.
Hope to get information when there is an update on Avast that fixes this.
