Halo experts

please help me, I first got to know the mail server and just used the hmail server. please help me how to add a ssl / tls certificate, and how do I get it? now I have added port 465 in SMTP. My email can't send mail to the Office 365 mail server (Remote server replied: 550 Requested action not taken: mailbox unavailable). And there is an issue that office 365 cannot receive emails that don't have an SSL / TLS certificate. so please help me, because I was pressured by my boss. :roll: :roll:

thanks
best regards
tomy

Unrelated to certificates. I would suggest you look at this first. "Mailbox unavailable" is probably because you are typing the wrong address but cold be because it is full. Look in your logs for SMTPC entries of the attempted delivery.

#1 connections to another server use that server's certificate, not your server's certificate

In SMTP >> Advanced >> Delivery of email
There is a check box 'use startTLS if available'.

Check that if it is not checked and that will secure your connections to outlook.com servers

#2 jimimaseye's advice is correct for the error that you posted

#3 Adding a certificate to hMailserver will ONLY impact on connections TO your hmailserver

You can make one, you can get a free one from LetsEncrypt, or you can buy one
Self signed (where you made it) will likely give you grief when connecting clients to your server.
Lets Encrypt requires some initial work, and is not for NOOBs
Purchasing a cert is an easy option

Make sure that your certificate includes a chain, and doesn't have a password

how to add ssl/tls certificate to hmailserver
Settings >> Advanced >> SSL Certificates

You then need to set up ports for encryption in Settings >> Advanced >> TCP/IP ports
