Email Access From PC Email Client After Terminationg AT&T DSL Internet Service

I currently have a AT&T DSL internet service account and using an email address "[email scrubbed]" but will be terminating service. 

I use a Windows PC bases email client and have 10 years of emails on this account. The PC based email client is configured to send and receive email to the AT&T email address "[email scrubbed]" with the following configuration.

   Incoming POP3 Server: pop.mail.yahoo.com   Port: 995   TLS Server Authentication

   Outgoing SMTP Server: smtp.mail.yahoo.com Port: 465   TLS Server Authentication

Here is my question. Will I still be able to send and receive emails using my existing [email scrubbed] email address with the same Incoming and Outgoing Email servers as described above after my AT&T service is terminated?

Thanks in advance for any guidance.
