I cannot connect 587 port for Contact Mails

Hi everyone,

I cannot associate my mail via 587 port on my VPS -Cyberpanel Server. However, I can login my mail via 25 port. But this time, when someone uses the contact form, I recieve the text and an e-mail from “MAILER-DAEMON@server.example.com” how can I fix this? Can someone help me? :confused:

Many thanks for this help… I have my own SSL from GoDaddy, I had added it to my website but, I couldn’t delete it, before that how can I delete my own SSL? Because it does not support mail services…

You don’t need to delete your old SSL. Basically, this article will solve your first problem (“MAILER-DAEMON@server.example.com” )

It will set the domain as mail server hostname, here you need to choose the domain which is also set as RDNS. I would suggest you to first create a website such as mail.yourdomain.com, then issue mail server SSL.

Then also set this domain as RDNS, and the second article is to help you solve your 587 issue.

I have done this, sir. However, I am still using GoDaddy’s SSL, and because of this, I cannot login my mail via 587 port. Because my own SSL does not support mail services. If I can remove my SSL, and then I can associate let’s encrypt ssl, it will work :s

As I recommended setup a subdomain and issue SSL for it, for the main domain you can keep Godaddy SSL.
