Common causes and fixes:
- Wrong settings. In cPanel, open Email Accounts ’ Connect Devices to see the exact incoming/outgoing server settings for your address, and match them in your mail app.
- Mailbox full. If your inbox has hit its quota, new mail bounces — delete old messages or increase the quota in cPanel.
- Wrong password. Reset the mailbox password in cPanel ’ Email Accounts.
- Domain still propagating. If the domain is new or recently moved, email may not flow until DNS settles (up to a day).
If mail still will not send or arrive, WhatsApp us and we will look at the mail logs.
