To clarify, have you tried changing the incoming port number in Outlook?

Also, another suggestion is to alter your user ID in outlook to look something like, “yourname#pop3.yourisp.com@localhost” or “yourname#mail.yourisp.com@localhost

Are you using Outlook or Outlook Express?

And another suggestion is to look in directory C:\Program Files\Alwil Software\Avast4\Data for the Avast4.ini.

open the file using notepad and the section [MailScanner] and add “:1110” (exception the quotation marks) to the end of the line “defaultpopserver”

Example: DefaultPopServer:1110=mail.yourisp.com

This will change the defaul port 110 to 1110 for Avast email scanner.
