HMAIL Email Server SSL Setup Diagnostics Failing on Port 443 - Do I also need Port 25?

I have setup my Hmail Server.  I have changed my TCP ports to all use my SSL Certificate.

The Diagnostics now fail as it still looks for port 25.  If I add Port 25 it works fine.  Does this affect my SSL security or is it needed to receive mail from unsecured users that only use port 25??

Do I need to have an Unsecure Port 25 open for it to work?

Is the security then managed by the Email application on the users computer being setup to SEND and RECEIVE using the SSL port?

My Hmail TCP IP Address Settings - Only for SSL
The Image below shows the diagnostic result.. If I add Port 25 for the same IP it WILL work.

You normally keep port 25 open for unencrypted emails and create a secondary port, check "Use SSL" on it and then configure the email clients to send email using the new port.

And yes, it's the email client's job to use the encryption.

But do not use the same port for POP, IMAP and SMTP. That's asking for a lot of trouble. I recommend using the standard ports: 995 for POP3, 465 for SMTP.
They'll be automatically selected on the email clients when your users check "Use SSL" and you'll have one less thing to go wrong.

Thankyou Dan.. that helps clear things up a bit.  I have the SSL using port 443 through the IIS8 server which runs my mail.domain.com.  Will the SSL certificate still "see" SMTP and POP3 using those default ports or is not restricted by which port it is assigned to in IIS?  Do the settings I have look like all that should be present?

New Hmail TCP Settings
The following settings from outlook 2013 do not work and prevent send receive.  I even turned off windows firewall at both ends and tried many combinations with no success.  If I turn off SSL settings and use standard 25,110 ports in outlook it all works fine.

443 is the standard port for https. That's what IIS uses.

For email you should use different ports: 995 for POP3, 993 for IMAP, 465 for SMTP.

So remove the 443 port from Hmail, add 993 only if you use it (ie you have users using IMAP).

Did you restart your Hmail Server after switching ports? These are the steps:

1. Start hMailServer Administrator
2. Navigate to Settings->Advanced->TCP/IP ports
3. Select/create a port
4. Select "Use SSL" and the certificate.
5. Save the changes
6. Restart hMailServer

Hello Dan...
pls note i found my solution here  HMailserver Forum Fix SSL issues

I ended up using openssl to discombobulate the ssl certificate and make a private and public key which is then referenced by hmail.

Now outlook 2013 works with full ssl settings turned on whereas before it would not authenticate with the server.  There are probably other solutions but the one from 'minimalist' worked.
