Desktop clients.
WHAT YOU NEED
The same settings as any device.
From cPanel, connect devices.
THE APPROACH
Manual configuration.
Automatic detection frequently configures the wrong thing.
WHAT TO ENTER
Account type: IMAP
Server hostname, for both incoming and outgoing Full email address as username Encrypted ports Outgoing authentication enabled
AFTER SETUP
Test sending and receiving.
WHAT TO CONFIGURE
Which folder sent mail is saved to, so it matches the server's Sent folder Whether deleted mail goes to the server's Trash
THOSE TWO
If misconfigured, your sent mail does not appear on other devices.
A common and confusing problem.
FOR SEVERAL ACCOUNTS
Each configured separately.
Check which account is used when sending, to avoid sending from the wrong address.
WHAT TO BACK UP
If you have years of mail stored locally, that is a single point of failure.
With IMAP it stays on the server too.
WHAT TO CHECK
That all folders synchronise.
