Do you allow SMTP (email) whilst connected to IVPN?
We do not allow SMTP port 25 traffic to be sent through our servers. As this opens up the possibility to spam millions of people from behind our VPN servers, we have decided to block SMTP port 25 as a way to keep the reputation of our IP addresses in a cleaner state.
To send email while connected to our VPN servers, consider using a secure email connection. When email is sent over a secure connection, there may be a higher level of trust and the email may be accepted by the email service provider. Port 25 is the default outgoing email port, but this offers no security. Ports available for secure SMTP are 465 and 587, which include SSL or TLS. Check your email provider’s support documentation for details about which ports are available for secure outgoing messages.
