Mac OS X Mail lets you set up many, many outgoing mail servers. This is good, and it is flexible. In Mac OS X Mail 1.3 and later, it's also easy to remove any server you have added.

Delete an Outgoing Mail Server in Mac OS X Mail

Mac OS X Mail 1.3 and later

To delete an outgoing mail server in Mac OS X Mail:

  • Select Mail | Preferences... from the menu.
  • Go to the Accounts tab.
  • Click on the Outgoing Mail Server (SMTP): drop-down list.
  • Select Edit Server List... from the menu.
  • Highlight the SMTP server you want to delete.
  • Click - (beneath the server list) or Remove Server, depending on the Mac OS X Mail version.
  • Now click OK or Done.
  • Close the Accounts preferences window.

Mac OS X Mail 1.0-1.2

In versions of Mail prior to 1.3, things look differently. There seems to be no obvious way to remove an SMTP server from the list.

Fortunately, Mac OS X Mail keeps its settings in easy to edit XML files, though. While you can't delete an outgoing mail server from within Mac OS X Mail, you can delete it from the settings manually.

To delete an outgoing mail server from Mac OS X Mail 1.0 to 1.2:

  • Close Mac OS X Mail.
  • Open ~/Library/Preferences/com.apple.mail.plist in TextEdit.
  • Search for "DeliveryAccounts".
  • Delete the SMTP servers you want to get rid of.
    • The host name is in the string following Hostname.
    • Make sure you delete all of the account, starting with the <dict> tag and ending with </dict>.
