I can probably find many more articles about what you're encountering, but you get the gist ;)

This isn't related to wildduck.

I’m currently facing an issue with my SMTP server even though port 25, 456, 587 is open for both inbound and outbound traffic — confirmed on both my firewall and ISP side.

My repository: [https://github.com/Pharmastock/kohinoor-SMTP.git]

I’m seeing these errors repeatedly in my logs:

ERR! Sender/default/27416[2] id=4eezluxenuodo5r3 19a2b757543000eeb3.001 CONNFAIL domain=gmail.com local=Avinix-Solutions[0.0.0.0] remote=74.125.24.26:25 error=Network error when connecting to MX server gmail-smtp-in.l.google.com[74.125.24.26] for gmail.com: Connection timed out

ERR! Reverse resolve for 212.132.96.229: getHostByAddr ENOTFOUND 212.132.96.229

In short:
Port 25, 456, 587 is open (verified at firewall and ISP level)

Still receiving connection timeout errors when connecting to Gmail’s MX servers

Also seeing reverse DNS lookup (rDNS) errors for IP address (212.132.96.229)

We are not using any cloud server.
Our setup runs on a self-hosted physical server (OS: Windows Server 2022).

also my ip is not black listed.
https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a43.249.233.137&run=toolpage

Also my ip is :-
IPv6: 2001:4860:7:505::da
IPv4: 43.249.233.137

Please help me
can we connect on google meet ?

I feel like there's so many things wrong with this config. You didn't follow the installation instructions (You forked zone-mta instead of using zone-mta-template like it says in the readme), your pool has no ip addresses in it, and the config contains nonsense values probably generated by AI.

I'd advice you to just do the setup again, follow the instructions, do it properly this time.

can we connect on google meet ?

For me personally I'd have to bill at a freelance rate for that.

In your nameservers config you have a name instead of an ip. Do you actually use nameservers? If not, then disable the corresponding config. The ip in pools.toml, are you sure you can use it? Double check just in case. Please check zone-mta-template for original config again and follow it as well as you can and all should work fine.
