Error 200 when trying to send emails with SMPT

[petrik]

Anyone having the same problem: When trying to send emails, always same message "Error 200" nothing else.
-> I have tried SSL/ TLS and without security in SMTP settings, but server refuses to send the smtp-mail messages.
(Fetching emails using IMAP works fine).

Is there somewhere a list or error codes? like what 200 happens to mean?
More importantly, what should be checked first?
Problem started already with earlier version of 5.6.0 and after installing 5.6.1 -> 5.6.2. no change on this.

Br, Petri

Hello.
If you are using the shared email host, try to find in its documentation the proper configs for the SMTP and IMAP connections.

Hi Maximus!
Funny thing is that the mailing did work nicely earlier, but simply stopped by giving the "error 200" . Any idea what error 200 means in EspoCRM?

The error 200 is not returns by EspoCRM. It returns by a server. If this error was returned by the email server so here is the list of the SMTP reply codes https://www.greenend.org.uk/rjk/tech/smtpreplies.html.

Thx Maximus, I discussed with the SMTP server provider. They said that they changed the SSL to TSL -> and espeially to TSL 1.2 (newer). They asked if the espoCRM supports TSL 1.2 encryption. Any idea of that? Or where I could check that?
