If you have created an e-mail address and want to add it to an e-mail client such as Microsoft Outlook or Mozilla Thunderbird, you will need the SMTP data from the server.
Here are the details:
IMAP (incoming server)
Server: yourdomainname.com
SSL port: 993
Non-SSL port: 143 (do not use it in principle)
SMTP (outgoing server)
Server: yourdomainname.com
SSL port: 465
TLS port: 587
(one of these ports is good)
Non-SSL port: 25
POP3 (incoming server)
Server: yourdomainname.com
SSL port: 995
Non-SSL port: 110 (do not use it in principle)
