To set up your mailbox on an Apple iPhone or iPad, you can need to:
- Open Settings > Mail > Add Account > Other > Add Mail Account, then you'll need to fill the right configurations for you mailbox:
Name: Anything
Email: example@yourdomain.com
Password: Mailbox Password
Description: Work, Business...etc
IMAP:
Incoming Mail Server
Host Name: mail.yourdomain.com
Username: example@yourdomain.com
Password: Mailbox Password
Outgoing Mail Server
Host Name: mail.yourdomain.com
Username: example@yourdomain.com
Password: Mailbox Password
Once you've finished setting up the mail account, click on save and then edit the account, press on advanced and turn off the SSL.
Finally, go back and press on SMTP under "Outgoing Mail Server". Primary Server > Use SSL should be also turned off.
