On the Mac, the Mail application connects to your mailbox by IMAP: messages stay on the server and the Mac displays them, so they look the same on the phone and in webmail. You need three things: the full address, the mailbox password (not the cPanel one, nor the My MozOut one) and the server name, which is mail.yourcompany.com, swapping in your own domain.
Adding the account, step by step
| 1 |
Open Mail. If it is the first time, an assistant appears; otherwise, in the Mail menu, choose Add Account.
|
|
| 2 |
Choose Other Mail Account… and click Continue.
|
|
| 3 |
Type your name, the full e-mail address and the mailbox password. Click Sign In.
|
|
| 4 |
If Mail cannot find the settings by itself, it asks for them. Pick the IMAP type, and type mail.yourcompany.com for both the incoming and outgoing server. The user name is the full address.
|
|
| 5 |
Tick only the Mail option to sync and click Done.

Checking the ports
Mail usually gets the settings right, but it is worth checking. In Mail’s settings (the menu name changes a little between macOS versions), open Accounts, pick the account and the Server Settings tab. If the ports are automatic, untick the automatic management to see them.

For the outgoing server, under Outgoing Mail Account, choose Edit SMTP Server List…, select the server and, under Advanced, set the port and SSL as in the table.
When it will not connect
| What you see |
What to check |
| Mail asks for the password again and again |
The mailbox password was changed, or you typed the cPanel one. Reset the mailbox one in the account settings. If you forgot it: changing an e-mail account password. |
| You receive but cannot send (outgoing server offline) |
Almost always the sending authentication or port. Review the table above, paying attention to port 465 and SSL. |
| The account shows “offline” |
In the Mailbox menu, Take All Accounts Online. If it drops again, check whether webmail opens: if it does, the problem is on the Mac. |
| Old messages are missing |
IMAP shows what is on the server. If the mailbox was emptied or is in another account, it does not come by itself: see POP or IMAP. |
|
If Mail warns that the certificate is not valid, do not click Continue blindly. It nearly always means the server name differs from mail.yourcompany.com. Fix the name instead of accepting a certificate from a server you have not confirmed.
|
|
Sent messages staying “only on this Mac”? In Mail’s Mailbox menu, the Use This Mailbox For option lets you say which folders are the account’s Sent, Drafts and Trash. When you cannot connect at all, the list of causes is in why your e-mail is not sending or receiving.

Does Mail keep asking for the password or refusing the connection? Tell us the macOS version and the exact message.
