Setting up iPhone
From HostBaby Wiki
This should work for iPhone and iPod touch (incidentally same settings will work for Google's Droid phones):
1. Select settings on your iPhone
2. Select Mail, Contacts, Calendars
3. Select Add Account
4. Select Other
5. Select Add Mail Account
6.Make sure the IMAP tab is selected, then enter the following:
(1) Name: Your Name
(2) Address: Your FULL email address. (ex: joejoe@hostbaby.com)
(3) Password: The password you chose when setting up your email account, or your default HostBaby password if this is the default email account we created for you.
(4) Description: Whatever you wish.
7.Click Save
8. Now enter the following:
Incoming Mail Server (IMAP):
(5) Hostname: yourdomain.com
(6) username: Your full email address (joejoe@hostbaby.com)
(7) password: Your email password
Outgoing Mail Server (SMTP):
(8) Hostname: yourdomain.com
(9) username: Your full email address (joejoe@hostbaby.com)
(10) password: Your email password
If it asks you if you want SSL the answer is yes.
9. Click Save. The initial setup process will begin. It may take a minute or so to complete.
You may get one or more secure server warnings (image below). Just click Continue.
The Port numbers should change automatically, but if not, or to double-check, the default SSL ports are (or should be):
* Incoming POP3 (SSL): 995 * Incoming IMAP (SSL): 993 * Outgoing SMTP (SSL): 465
That should do it! Go ahead and test it out.
