How do I select a new SMTP "Primary Server"?
On my iPhone (iOS 11.2.5), I had to change the SMTP server for my e-mail account. I was able to add the new SMTP server, which appeared under "OTHER SMTP SERVERS". I was also able to turn off the old SMTP server (which is shown under "PRIMARY SERVER", so I only have the new SMTP server active. I am able to send mail successfully.
My question is: How do I switch my Primary Server to be the one that is active? Does it even matter?
Solution 1:
I haven't figured out a way to rearrange the servers so that a different one is the Primary, but I was able to work around it by simply tapping on the Primary server entry and change the details so that it points to the server that I want. That way, the one I am actually using is the Primary.
As Christian said in the comments, it doesn't matter, because if I only have one server actually turned on, that is the one that Mail will use.
