Problem sending e-mail
On my ipad I can't send any mail as long as VPN is turned on. As soon as I turn it off, the mail is sent. Receiving mail is no problem. The errormessage says the server doesn't recognize the receiving address. Can you help me?

You will have to open a support ticket to get this done, or to get a better explanation of how and why they do this.
How do other people do this, since everyone sends mail?
Sorry I was not clear enough when I replied the first time.
You're right, this should be published where prospective users can find it before signing up. Like so many other things (still waiting for advanced crypto options for use without official client for over a year!).
The common providers could be whitelisted, but you might have to use certain IP addresses instead of the hostnames. Support should be able to tell you about specific providers (but lately their default answer seems to be "go to the forums, we don't know").
An easy and usual blocking rule is to block port 25, because 25 is where SMTP is spoken between MTAs, and it's usually understood between sysadmins/postmasters that end user systems have no business talking to anyone but their ISP's/provider's mailservers. Regular users usually follow this rule, either by using their ISP mailservers from their ISP networks or using different ports for authenticated connections. Old school spammers just pretend to be another MTA and will try to connect via port 25.
All other port blocks should be dropped, but obviously someone at PIA knows better so the blocks are here to stay.
I apologize, but your mail servers are configured such that whitelisting is not possible.
When I asked them what should I reconfigure, they didn't say anything usefull again.
You will need to contact your mail client to find out that information, as it is not something we are able to support with.
The first request is dated June 3, 2017 and ticket numbered 363882..
Please respond Mr. Jason Q, or anyone, please.
