I have installed the Avast! Version 9.0 on my Mac Book Pro running OSX 10.9.3 and running the Mail version 7.3
When the Mail protection in Avast is activated several of my email addresses are completely blocked.
These are my POP type email addresses at the 1and1.com email server. The one IMAP address (Gmail) I am running is unaffected.
Problem Analysis:
Avast leaves a single smtp address online running but puts all the other smtp server addresses, which are the same smtp address but used by different emails, to 'offline' status thus blocking all usage, in or out, of these email addresses. Avast leaves only one primary smtp address online and working.
Even when one resets the email addresses in the Mail program itself back to online status, Avant blocks these and resets them back to offline.
Since I have several POP email box addresses at my 1and1 account, each for different purposes I cannot use avast email protection until this problem can be solved.
