9998 doesn't work either, only 17017 works

I tried completely uninstalling RDWEB and ISS and then reinstalling SmarterMail and it still doesn't work 9998 even after changing to 80 bindings 80 doesn't work. I will not create Let Enscrypt certificates without 80

It's the first installation on server 2022, so I don't know if it's IIS 10 or AD, I can already rule out RDWEB

I sell pictures

17017 ok

9998 not work

80 not work

after completely uninstalling RDS, the situation is the same.

Clean installation of SmarterMail does not work

RDS none!

Youre doing it wrong. :)

Bind port 80,443 to your local servername in IIS.
Bind port 9998 to localhost in IIS.

On 443 bind your local certificate to your servername.

It doesn't work

I deleted the default website and the Smartermail website,

uninstalled smartermail, deleted the folders after installation, and after reboot started a new clean installation

localhost:17017 - OK

localhost:9998 - doesn't work

error

I don't understand the exact recommendation of what to do

do you have a link with a description or pictures of exactly where I should set it?

I need to have a functional RDS, so I have to have an Active directory.

RDS - RDWeb has * 80 and * 443 connection under Default web server

After SmarterMail is installed, the SmarterMail website is added to IIS with binding *9998

Its not recommended to have RDS installed on a service running a mailserver.

Loads of cybersec issues in that constellation

I know this is a kindergarten level question, but since SM was installed when there was another IIS instance running...... is the Smartermail site (as shown inside IIS manager) in the stopped or running state?

We've hit that snag a few times over the years.
 

Security 101: STEP1: Do not run IIS and non-AD required websites on a DC.

STEP2: See step 1.

HI !  

1) Are you using a Firewall in front of the 2022 server, or is the 2022 servers exposed directly to a public IP Address ?  If you are using a firewall then do you have the ports open in that firewall ? If you do not have a firewall, I would recommend pfSense in front of that server.

2) Just FYI, When Zach is referring to a "site" he is talking about the "sites" inside of the IIS Settings. When I first heard sites i thought they were talking about websites. When Smarter Mail is installed, you may have to manually create an IIS "Site" called "webmail" or "SmarterMail". On our server with an older version of SmarterMail, the "Sites" were not automatically created and i had to manually create them.

Opnsense is a lot better than pfsense in the current state.

Just FYI. Much better support and a real opensource project.
