Email connectivity issues for Comcast customers
If you are having issues with email lately and are a Comcast user please read:
Comcast has changed the settings on your modem / router for connecting to email. If you have a computer wired to the modem / router you will need to change your outgoing SMTP port to 597. Generally the port should say 26 for POP and 465 for IMAP.
Changing this setting should get you back up and running with no issues.
