The best knowledge comes from practical experience.
Install a protocol analyzer (Ethereal
<http://www.ethereal.com/> is free) and look at real
world data. If you don't have access to a business
network to examine, use your home network, or you can
get sample packet captures
<http://www.ethereal.com/sample/> to start with.
That being said, in my opinion, the second best
knowledge comes from O'Reilly books. Take a look at:
Internet Core Protocols: The Definitive Guide
<http://www.oreilly.com/catalog/coreprot/>
TCP/IP Network Administration, 3rd Edition
<http://www.oreilly.com/catalog/tcp3/>
Building Internet Firewalls, 2nd Edition
<http://www.oreilly.com/catalog/fire2/>
You might want to think about a Safari
<http://safari.oreilly.com/> membership to save some
money on the cost of the books.
Many community colleges offer low cost classes in
networking and computer security, usually taught by
people with experience in the industry. Many colleges
also offer Cisco Network Academy classes
<http://cisco.netacad.net> as well.
Hope this helps, best of luck to you.

I'm sure they
exist, I simply haven't stumbled across them yet. It
took me several
tries with Google to find an explanation of SMTP; even
then it wasn't
obvious from the search results. Perhaps if somebody
would make a
website or (inexpensive) book dedicated to topics such
as these, more
geeks/professionals would have a knowledge of it.
And that concludes my outsider's view. :)
