Pretty self explanatory, Avast Free Antivirus is blocking Windows Live Mail from sending an email to Bigpond’s SMTP server at mail.bigpond.com.
I get the error message:
An unknown error has occurred.
Subject 'TROUBLE ENTERING ’
Server Error: 421
Server Response: 421 concurrent connection limit in avast! exceeded(pass:15, processes:ccsvchst.exe[49], wlmail.exe[1])
Server: ‘mail.bigpond.com’
Windows Live Mail Error ID: 0x800CCC67
Protocol: SMTP
Port: 25
Secure(SSL): No
Would like some help to fix it so I can send emails again.
