[comp.mail.misc] How can I learn more about SMTP?

andy@garnet.berkeley.edu (Andy Lieberman) (06/17/89)

Is there some sort of spec available with all the details
of SMTP?  I am interested mostly in the protocol itself,
but would also like to learn more about how it fits into
the whole world of e-mail (i.e., how widely is it used,
what are some competing protocols, etc.).

Thanks in advance,
