Apple Mail Not Working

I am with Comcast and have several apple mail accounts set up. They all suddenly stopped working today. I kept getting a message that there was no outgoing server selected. They are all POP accounts and have been working fine until a few hours ago.

MacBook Pro, OS X El Capitan (10.11.1)

Hi Nancy,


Thanks for using the Apple Support Communities. I know it's important to keep your email working to keep in touch with friends and family, so I'm happy to provide you with some direction to fix that outgoing server.


First, make sure you've got all of the correct settings for your email account. You can find out what things you may need here:


Mail settings you might need from your email provider


Once you've got the settings from your email provider, check that they are in your Mail app correctly by opening Mail and then using the menu bar to open Mail > Preferences > Accounts. Select your email account from the left, and verify that all settings are correct.


Cheers!

EDIT SMTP SETTINGS


In Accounts window > Outgoing Mail Server SMTP: select to Edit SMTP Server list... from popup.


Select account in the list.(It's not uncommon to find extra SMTP servers listed. When you remove account, Mail does not delete the smtp info. You might need to do some clean up in the list to remove the extras.)


Under Advanced Tab:


Apple defaults to the default ports (25,465, 587) but some servers prefer a custom port. Check to see what port they recommend. Gmail for example likes 465, Outlook.com 587, Comcast 587.


Verify if your server require SSL. (Comcast does require SSL)


User Name. Enter full email address eg. UserName@gmail.com

Add password if it is blank.


Open Connection Doctor under Window in the Menu bar.

Do you see green light now for your account SMTP?


If you have green symbols for your Comcast POP account, go back to Accounts window and select your Account and then select the correct SMTP server from the list. You might be able to select "always use this server".

Is the POP account also Comcast?


For the longest time Comcast only offered POP. Now you can setup as both POP and IMAP. I highly suggest you move to IMAP.


Apple Mail will want to default to setting up as IMAP. See Barney's post on how to configure as POP.


Configuring a POP email account in El Capitan Mail


Comcast settings for POP. Note you must use steps in link above to make it setup as POP.

Incoming: mail.comcast.net

Use SSL


Outgoing: smtp.comcast.net

Port: 587

Use SSL

PW required: full email and password
