Greetings,

I am trying to configure email on iPhone but am getting a message that "server is not responding"
but when you try to send email from the phone it sends but not receiving.
Tried to set IMAP & POP with vail.

Please use port 587 with STARTTLS secure connection for smtp service.

FYI: Https://docs.iredmail.org/#mua

Buy me a cup of coffee ($5) to support iRedMail:

Re: Cannot Configure IMAP/POP on iPhone

iPhone has a generic "USE SSL" to be set on, but you can change the port from 465 to 587 (submission).
when sending mail, you'll see in maillog that it uses TLS1.3 protocol, not SSL.
Just checked now with an old iPhone SE, updated to IOS ver. 14.7.1

For incoming mail, in a working device, my configuration is the same as yours.
You have to check dovecot log files.
