Newly installed 9511 - Need help enabling webmail on port 443
Problem reported by David Short - 1/24/2026 at 9:48 AM

Upgraded to 9511, moved away from hosting IIS to service the webmail, enabled "Force all traffic over https" on general settings but can't connect to https://localhost or actual URL for webmail.

Anyone else experience this?  Chatgpt tried to tell me to create a new binding for the IP address but there is no http option for bindings...

On windows, turn the require https feature off.   Webmail connects to IIS, where you can require https.   Then IiS relays the traffic internally over http to SmarterMail on port 17017.  Ensure that your firewall prevents non-local access to 17017.

Hopefully you can connect locally to port 17017 to fix the setting

Thanks for the response. I was actually able to utilize the features built into build 9511 and sunset the IIS portion of this installation.  Everything is back working again. I appreciate your guidance.

FYI do not run 9511 run 9518 there are critical security bugs in 9511

@Jade - the auth bypass is against builds 9504 and lower.

Build 9511 has a seperate "unknown" vulnerability that exists but it is not documented anywhere.

The link I shared is the aftermath post the patch releases in 9511.

The op should run only the latest version of smartermail.

In 9511 the built‑in web server must explicitly listen on 443.
In Settings → Bindings → Ports add/enable an HTTPS binding on port 443 for your IP and assign the certificate.
Make sure IIS (or any other service) isn’t still using 443 and allow it in Windows Firewall, then restart.

Do not use 9511 and upgrade
