iOS: Configuring additional outgoing mail servers

When you configure your email account on your iPhone, iPad, or iPod touch, you may want to add additional outgoing mail servers.  Depending on your ISP, you may not be able to use the default outgoing SMTP server when using certain Wi-Fi or cellular networks. This article outlines how to setup additional outgoing SMTP servers.

If you need to add an email account on your iOS device, see adding an email account.

To add outgoing mail servers to an existing email account:

  1. Tap Settings > Mail, Contacts, Calendars.
  2. Tap the Mail account for which you would like to change the settings. If you configured your account using any of the built-in presets, IMAP, or Exchange, you may need to tap Account Info on the following screen.
  3. 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 Other SMTP Servers.
  4. Tap Add Server… under Other SMTP Servers.
    SMTP settings
  5. Enter the additional SMTP server information then Tap Save.

Note: The Host Name is required. The Host Name is usually the outgoing server name. If you are unsure of the Host Name, or additional entries, please contact the email service provider you are attempting to add.

You can use the same steps as above to either turn on or off or remove an existing SMTP server by tapping the SMTP server you wish to adjust instead of tapping Add Server….

  • Not all email service providers support additional outgoing mail servers on iOS devices.
  • If an SMTP server is being used as a Primary SMTP server by any account, you can't delete it without removing that account. Instead, disable the server.
