Hi, my server works great with Windows and Android clients. Unfortunately, the iOS mail client says: "Cannot verify server identity". It shows the server certificate, but there is no option "Trust". Please, could anybody help me with the issue?

Get a free ssl cert from LetsEncrypt to make all clients happy:


Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

Re: Login problems with iOS

Thanks a lot ZhangHuangbin. Unfortunately, it's just part of the solution. Apple removed "Trust" option from their certificate settings options. Finally, I was able to solve it like this:

1) Install LetsEncrypt certificate ( on other hand it doesn't matter, which free certificate )
2) Send ti to another account on an Apple device with the newest iOS ( fullchain.pem file from LetsEncrypt )
3) Click the certificate in the email on the Apple device => install it -> add it to trust ones

After this, it started to work.
