Re: no authorization by smtp

Please use port 587 with TLS instead, port 465 is not enabled by iRedMail by default.

Re: no authorization by smtp

You can try to enable port 465 then: https://docs.iredmail.org/enable.smtps.html

Re: no authorization by smtp

Please make sure your php script uses correct network port and secure connection:

- Port 587, STARTTLS
- Port 465, SSL

With other mail servers sending emails works, for example Gmail. I tried already ssl 443, starttls 587. The problem is not solved.

On a local network, sending via smtp through 587 works. And if you connect externally, it does not work. Checking telnet ***.***.***.*** 587 connection is.

Re: no authorization by smtp

Don't use telnet to check a ssl/tls connection. Please try it with a MUA like Thunderbird.

Smtp works in Thunderbird. But not on web resources. Moreover, the smtp connection works in the local network.
