When you were using Comcast servers, it most likely was from your home computer with Comcast as your service provider, and you were probably using port 25. In this situation, SSL/TLS is not required.

My local ISP is not Comcast, so I can only guess what Comcast does or what it allows. Since you are on Comcast, I will presume Comcast is not requiring SSL/TLS for connections from its own network. If you attempt to connect to a server other than from Comcast, then SSL/TLS is most likely required to prevent your credentials from being sniffed by equipment between you and the intended POP and SMTP servers. SSL and TLS are encryption standards, designed to prevent anyone from determining what data you are sending and receiving, including user ids and passwords. So far, TLS provides a stronger method of preventing your data from being sniffed out than does SSL.
If you review the Yahoo pages, you will find they require SSL/TLS connections. Here is the page to review:
Incoming Mail (POP) Server
a.. Server - pop.mail.yahoo.com
b.. Port - 995
c.. Requires SSL - Yes
Outgoing Mail (SMTP) Server
a.. Server - smtp.mail.yahoo.com
b.. Port - 465 or 587
c.. Requires SSL - Yes
d.. Requires TLS - Yes (if available)
e.. Requires authentication - Yes
Your login info
a.. Email address - Your full email address (***@domain.com.)
b.. Password - Your account's password.
c.. Requires authentication - Yes
For me at home, I use different profiles with Blat so I can choose to use SSL/TLS or not, on a per server basis. When sending to my local cable provider, I do not need SSL or TLS, so I tell Blat to send directly to my service providerâs SMTP server on port 25. When sending to any other SMTP server, such as AT&T that I use most frequently, then I use a program called stunnel to provide the SSL/TLS connections. For these other servers, I have Blat configured to send to 127.0.0.1 on different ports that I have designated for different SMTP servers. My stunnel configuration file tells stunnel on which ports to listen, and where to route traffic when anything is received on those ports it is listening to. Stunnel can run when Windows starts, it sits in the background quietly listening for any connections to ports it is configured to listen to. This program occupies less than 5 MBytes of memory, and no CPU cycles when quietly listening.
Stunnel can be freely downloaded from https://www.stunnel.org/. If you want help getting it configured to use with Yahoo, I can post my configuration file again, or you can search the Yahoo messages for stunnel and find many references to this fine program and configuration files.
