Email Domain not accepted

I have problem with the following domain:

If I set for outgoing IMAP then accepted,
but beside I set it for SMTP the it just SAVE for apprx.
5 minutes and then nothing saved.

If I set for email incoming it works, but if I set for OUTGOING on the same form
is not saving at all.

I can’t set IP DNS address, it changes rapidly.

Please help me out on this.

In the mean time found out
The Smtp
Tsl port not accepted.

The tsl port number is: 465

Do this port 465 not alloved by default in ERPNext?

imap is inbound and smtp is outbound krnkris

To troubleshoot http, https, smtp, pop3, imap etc service connectivity, first identify the port that the tcp service runs, then confirm that the port is open. So for example

frappe@erpnext:~/frappe-bench$ nc -vv 587
Connection to 587 port [tcp/submission] succeeded!
220 ESMTP l22sm30607654pfi.2 - gsmtp

frappe@erpnext:~/frappe-bench$ nc -vv 993
Connection to 993 port [tcp/imaps] succeeded!

You will find more checks here

@clarkej , appreciate taking your time!

~$ nc -vv 465
Connection to 465 port [tcp/urd] succeeded!

The problem is maybe because the connection is tcp/urd ???

I made yesterday a backup/restore and from this point ERPNext can’t handle the SMTP.

If I fill out the “new” domain, for the

Everything is fine, only if I check the TLS + write the 465 port then it cause problem.

OMG !!!

I made mistake !!!

I should not fill out the port, because the port 465 is STANDARD for TLS.

Now everything works fine,.

Thank you!
