Q: Cannot send mail-

Hello Norqualj,

Thanks for using Apple Support Communities.

To troubleshoot this issue where you cannot sent email from your AOL account in Mail because it does not have an outgoing mail server, please delete and add your AOL account back.

 

Remove an account

When you remove an email account from Mail, the account’s messages are deleted and no longer available on your Mac. Copies of messages remain on the account’s mail server and are still available (from webmail, for example).

Important:   If you’re unsure whether messages you want to keep are still on the mail server, move or copy them into a mailbox stored on your Mac (the mailbox appears in the On my Mac section in the Mail sidebar) before you delete the account in Mail.

1. Choose Mail > Preferences, then click Accounts.

2. Select an account, then click Remove .

Mail (Yosemite): Set up Mail with your email accounts

 

Set up Mail

When you first open Mail, you're prompted to set up your email account if you haven't already. 

Choose your email provider from the list. If you don't see your email provider, click "Add Other Mail Account." Then click Continue.

Mail asks for your name, email address, and email password. Fill in this information, then click Create. 

 

Mail completes your account settings based on the email address you provide, and in Yosemite, Mail automatically maintains them.

• If Mail doesn't recognize your email provider, it might ask you for additional settings.
• If you need to add more than one Mail account, start with your primary account. Then use Internet Accounts to add more accounts.
