Q: Mail server in El Capitan not working from iPhone
I made a clean install of El Capitan 10.11.2 and then Server 5.0.15 on my local network. Then I started the mail server from Server to use it as my IMAP mail server.
It works just fine från all my Mac's (Apple Mail or Thunderbird) and PC's (Thunderbird).
But when I try to read my e-mail från an iPhone or Android, it doesn't work. My iPhone complains that "Logins are disabled for "xxx" where "xxx" is one of the users that I created from Server. The mail.log file doesn't get any new entries when trying. One thing that disturb me is that the status line in the Mail screen in Server says "Available on your local network at Server.local" instead of "Available at montan.biz" at it was in my previous installation that worked.
What can be wrong?
Mac mini, OS X El Capitan (10.11.2)

****, now I'm, blushing from shame.
I've solved it. Now with your help, but all your advice has made me look in the correct direction.
When I tried to connect to port 143 from my phone it said "can't connect with SSL, should I try without SSL" and I said "yes". Then it can't connect as my mail server seems to require SSL for the authentication.
Then I changes to SSL in my phone, but then it changed port to 993, which was not opened in my router's firewall.
I just feel like an idiot. My only excuse is that I was focusing too much on the error message.
Thank you very much for all your help. It has at least given me a lot of knowledge that I can use in the future.
