i don’t know if we’re on the same page but usually it’s the following combinations that lead to e-mail problems ( i understand that this thread is like a year ago ) :

1: incompatible antivirus and firewall (i.e. zonealarm and AVG antivirus [only once due to one of their updates])
2:two firewalls ( for some odd reason )
3: two antiviruses because if they both have e-mail scanning at the same time and conflict with each other.

cheers,
