And I must add that in newer versions (>= 4.5) unless it is explicitly specified in the avast4.ini (by ImapListen=127.0.0.1:143, PopListen=127.0.0.1:110, SmtpListen=127.0.0.1:25) avast’s Mail Scanner listens on other (non default ports).

So, check your avast4.ini and if the lines mentioned above are not present please use the followinG setup.

IMAP server: 127.0.0.1
IMAP username: NAME#imap.aol.com
IMAP port: 12143
SMTP server: 127.0.0.1
SMTP username: NAME#smtp.aol.com:587
SMTP port: 12025

:-[ I don’t know correct setting for POP3. Does AOL provides such an access to the mailbox?
