Hi All!
Today, I tried to send an e-mail and found that Mail.app could not send it because the outgoing server list (SMTP list) was blank.
Unfortunately it is blank for all ten of my e-mail accounts.

Rather than finding my list of server settings and typing my brains out, I did a Time Machine restore from a time when I knew Mail worked. (Restored User Name/ Library/Mail/V3)

Unfortunately, the outgoing server list was not filled back in.

Do any of you know where it is stored and how to import it (OS x 10.11.6 El Capitan).
Or... Am I out of luck on this adventure & have to re-enter them individually?

Thanks For Your Advice!
Paul
