iOS: Configuring additional outgoing mail servers
To add outgoing mail servers on your iOS device:
- Tap Settings > Mail, Contacts, Calendars.
- Tap the Mail account for which you would like to change the settings. If your account is configured using any of the built-in presets, IMAP, or Exchange, you may need to tap Account Info on the following screen as well.
- On the Account Info screen, locate the Outgoing Mail Server section and tap the existing SMTP entry.
- A list of SMTP servers will appear, with the Primary Server and then Other SMTP Servers. Tap Add Server…under Other SMTP Servers.
- Enter the additional SMTP server information. Host Name is required. Contact customer support for the SMTP server you are adding to determine if you need to enter information in the User Name and Password fields if you are unsure.
- Tap Save.
You can use nearly the same steps as above to either turn on or off, or to remove* an existing SMTP server, selecting the SMTP server you wish to adjust instead of selecting Add Server.
Additional Information
* If an SMTP server is being used as a Primary SMTP server by any account, it cannot be deleted without removing that account. Instead, disable the server.
