webmail url not working...also cannot creating mail lists in virtualmin

Hi guys,

one of my virtual servers did not have email enabled (first one in the virtual server list).
EDIT…I have since checked all the virtual servers and https://webmail.diomain.com url isnt working on any of them. (ERR_NAME_NOT_RESOLVED)

  1. Added the virtualmin suggested dns records at my registrar.

  2. Virtualmin>Features and Plugins> Mail for domain (checked/enabled)

I then navigate to Virtulamin>Services>“Virtual mailman mailing list” is missing from the list here

also,

when i attempt to navigate to https://webmail.mydomain.com in browser it produces following error

This site can’t be reached
webmaill.mydomain.com’s server IP address could not be found.
Try:

Checking the connection
Checking the proxy, firewall, and DNS configuration
Running Windows Network Diagnostics
ERR_NAME_NOT_RESOLVED

My browser at one point was changing url to use port 20000. Should it be doing this???

redirecting to https:mydomain.com:20000

This site can’t be reached
adamjamesedgar.com.au took too long to respond.
Try:

Running Windows Network Diagnostics
ERR_CONNECTION_TIMED_OUT

finally, mxtoolbox lookup…

pref 5 mail.mydomain.com xx.xxx.xx.xxx Google Inc. (AS15169) 24 hrs
DNS Record Published DNS Record found

Revers PTR is working correctly.

I can also send and receive emails from this server (I cannot receive emails with server admin user email, however after setting up a new user with email and an automatic reply this new account is working)

I have it sorted…what i did not realise was that Usermin url is as follows:

https://webmail.mydomain.com:20000 (the port 20000 is the important part…i had not allowed port 20000 on my server)

All that is required now is to get thunderbird working so that my incoming is using encryption.

Virtualmin>server configuration>manage ssl certificate> copy to dovecot and usermin. (done all sorted now)
