# Apple Mail

These instructions show how to add an SMTP server to an existing Mail account, but you can also add these settings at the account creation stage.

## Adding SMTP settings

Go to Mail -> Preferences (⌘,). On the account you want to edit, click the tab that says **Server Settings**, then click the **Outgoing Mail Account** dropdown and select **Edit SMTP Server List...**.

Next, click the **+** under the list of SMTP servers, and add a new one.

Then enter the server details:

* **Description:** SendGrid
* **User Name:** `apikey` (use the string `apikey` not your actual API key)
* **Password:** Set your password to the API key generated
* **Host Name:** smtp.sendgrid.net
* Uncheck **Automatically manage connection settings** if you want to specify Custom Ports, Encryption Type and Authentication
* **Port:** Specify the port
* **Encryption:** Check or uncheck Use TLS/SSL
* **Authentication:** Password

Now the SendGrid SMTP Server can be specified on the **Accounts** tab of the **Preferences** window in the **Outgoing Mail Account** dropdown. Once this is selected, mail sent out of Apple Mail going forward will use the SMTP server chosen until specified otherwise.

## Attachment Compatibility

Mail will sometimes attach images in a way that is incompatible with other email readers. However, this behavior can be changed so that Mail will send more traditional non-inline attachments.

1. Open Terminal (found in Finder > Applications > Utilities).
2. In Terminal, paste the following: `defaults write com.apple.mail DisableInlineAttachmentViewing -bool yes`.
3. Press return.
4. Restart the Mail app.

If you wish to restore the normal behavior of Mail, repeat the steps above while using the following command: `defaults write com.apple.mail DisableInlineAttachmentViewing -bool no`.
