How to config Thunderbird client?

[Q3tNHn]

Hi all, after I enable TLS option, the PMG only expose port 25 to public. How do I config Thunderbird then? Just indicate port 25 and no tls?

Erm… you usually connect Mailclients to appropiate MailSERVERS, not MailGATEWAYS ;-)

Sorry i should be more specific.
I am selfhosting an internal domain zone, Postfix+Dovecot+LDAP as backend mail servers and Proxmox Gateway. I want both internal and external email go through the mail gateway...

You would configure your backend mail to send mail out through the Proxmox gateway and then you would configure Thunderbird to send mail via the backend mail server.

To allow your backend mail server to send mail through your PMG you would add the backend mail server's IP address on the Mail Proxy -> Networks screen of the PMG admin interface.

I will try that. Thank you!

Hi I did that but it is still not working.

jchamb2010 correctly said to route backend server mail through PMG. But he missed that Thunderbird should connect to the backend mail server (Postfix), not PMG. The PMG should only handle mail from servers, not end-user clients directly.
Configure Thunderbird to connect to your Postfix server on port 587 with STARTTLS. Ensure Postfix allows authenticated connections from clients on port 587. Postfix then forwards mail to PMG, which handles filtering and external delivery.

I missed no such thing:

You're right! My mistake for misreading your reply earlier. Thanks for clarifying!
