Hi all,
Currently have my IredMail server ports 993, 587 and 25 directly behind my router.
I do have the IredMail ports 80/443 behind a Ubuntu22LTS nginx proxy server that also serves Letsencrypt certs.
Would it be recommended to move 993, 587, and 25 behind same proxy? If so, Would someone have a sample proxy nginx config file that I can use to create mine?
Regards
This is okay to do. Port Forward 80/443 for Nginx Reverse.
Port Forward 25. 587 and 993. I would not bother with Proxying SMTP & IMAP. You wouldn’t really gain much from this.
If you have one Static Public IP then I would suggest creating a separate VM for Nginx and configure it as a Reverse Proxy should not really run a Reverse Proxy on the same server it defeats the object.
Don’t neglect PTR (Pointer Record) for rDNS. This needs to be set by the ISP.
You also mentioned that your IP is Dynamic. I would not bother hosting a mail server with a Dynamic IP. Sending mail would require a PTR Record, sending mail would just get bounced back. I mean you could use DDNS & a SMTP relay service but no point.
Regards
