New Post: Email authentication

There is another point to keep in mind.

There are 2 types of SSL authentication

1. Implicit SSL
2. Explicit SSL
   

MCEBuddy ONLY support Explicit SSL (.NET limitation) - that is it expects the server to support the STARTLS command

Yahoo SMTP Mail default SSL with port 465 is Implicit SSL and will not work with MCEBuddy

Instead use Yahoo SMTP mail WITHOUT SSL and on port 587 and that will work.

Gmail uses Explicit SSL so that works perfectly. Google Implicit SSL for more details.
