I am new to cPanel and e-mail setup so I might be making a fatal error somewhere, but I cannot setup my webmail anywhere else than the Roundcube webmail app in the cPanel package. I can send and receive without any issues so the mail account itself appears to be correctly configured.

However, I've tried to set it up on Windows Mail and a couple of apps for Android on my mobile without success. I am using the suggested mail client settings as shown in the webmail settings in cPanel but still no luck. Windows Mail claims setup was successful but then tries to sync for a long time only to come up empty. I've tried disabling the firewall but that doesn't help. On the mobile app it says it fails to connect to the host due to timeout when trying to connect.

Can anyone figure out what I am doing wrong here?

Cheers!

Hey there! There are some tests you can do from your local machine to see if there is a port issue between your network and the server. If you have the "telnet" command installed in your Windows machine, you can try and telnet to the mail pots to ensure they are open.

I would start here: https://social.technet.microsoft.co.../38433.windows-10-enabling-telnet-client.aspx

and then run the following commands from your Windows machine:

Code:
telnet yourdomain.com ###
Where ### is the port number you are trying to connect to with the client. For example, if you are using port 25 for mail, you would run this:

Code:
telnet yourdomain.com 25
If that connects, the port is working. If not, the port is likely closed by your internet provider.

@cPRex Thank you for your reply. The telnet procedure couldn't connect to any port at all. After doing some more investigations, I found that the IP number which I get when I use the ping command doesn't actually match the IP number which GoDaddy lists as being linked to my domain. This should go far in explaining why I couldn't set my e-mail address on any client. I am contacting GoDaddy tomorrow to ask why the IP numbers don't match.
