we're not blocking any ports.
problem with email sending can be caused by your provider's outgoing email server (SMTP), if you are using it.
they usually restrict access to their email server from their networks (eg. you as their customer).
using secureline, all your traffic is going through tunnel and comes to their server from the "outside world", and they are probably blocking it.
my suggestion is to set the route to provider's mailserver manually, not to go through vpn tunnel (secureline).
