Common Questions
Why can't I receive emails while the VPN is active?
If you are using IMAP (Internet Message Access Protocol) for your Incoming mail settings, it is recommended that you use POP3 (Post Office Protocol) instead. Contact your e-mail provider for more information about your POP3 settings.
My email client is not listed above, what should I do?
If your email client is not listed, changing your Outgoing Server Port is very similar in other apps. Contact our support team or your e-mail provider for further assistance.
