Host Name: send.one.com
Username: your email account

Tap Next to continue.
Step 8 - Save the account
Tap Save to create the account. Note that syncing of notes is not supported via IMAP, so we recommend disabling the option.

You need to select the following folders on the server:

Sent mailbox: Sent
Deleted mailbox: Trash
Archive mailbox: Archive
If no folder, or a different folder, is selected, tap the mailbox and select the correct folder on the server. (The name of the folder is in English.)
Note: If the folder you are looking for is not listed, log in to Webmail and place an email in the folder that is missing. Then try again, it should now show up in the list.
Step 13 - Enter IMAP Path Prefix
Scroll down to the bottom of the screen and enter INBOX as the IMAP path prefix, all in capitals.
Step 14 - Done!
Your email account is now set up correctly on your iPhone.
