Not Receiving Mail

[Surf3rDud3]

I used mxtoolbox.com to check my SMTP Status and i get this.

Code:

Connecting to xxx.xx.xxx.xx 220 cp.domain.tld ESMTP [657 ms] EHLO PWS3.mxtoolbox.com 250-cp.domain.tld 250-PIPELINING 250-SIZE 20480000 250-ETRN 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN [625 ms] MAIL FROM:<supertool@mxtoolbox.com> 250 2.1.0 Ok [625 ms] RCPT TO:<test@example.com> 454 4.7.1 <test@example.com>: Relay access denied [625 ms] PWS3v2 3282ms

First off, I believe you need to be using mail.domain.tld instead of cp.domain.tld
That's what your MX records should be bound to and what Sentora configures all mail functions with.

I have mail.domain.tld set in for my mx record in my registers dns panel. If I need to change it somewhere then i will look for it.

Code:

It tells you what the problem is:

Code:

Relay access denied

Make sure:

Code:

smtpd_recipient_restrictions = permit_sasl_authenticated

(Change 'mydomain.com' to whatever yours is, also change 'my.servers.ip.address' to your server's external IP)

You will also need to remove the SSL certificate stuff if you are not using one.

Some settings I am sure are different as I am using a Let's Encrypt certificate for my mail.mydomain.com

Let's sort out your DNS issue first, then come back to this.

[Me.B]

Main issue if you can't receive email is either DNS not setup or ISP is blocking port 25. Postfix default config is fine.

[Surf3rDud3]

Thinking my DNS isnt setup correctly i already checked port 25 and its open. Ill have to mess with my DNS when i get home later today. Actually working at the moment. I have another thread open for my DNS problems.

[Me.B]

If you are having trouble setting up DNS in sentora you can still setup dns on your registrar or use cloudflare and it would work fine.

[Surf3rDud3]

Now that my DNS problem is sorted i still receive the Relay error when using mxtoolbox.com. Its not a major issue since i can still tecieve mail but programs like mailbird and outlook cant be used.
