[ale] Which /etc/services to allow for secure web browsing & email ?

[courtneycthomas at bellsouth.net (Courtney Thomas)]

My services file has thousands of entries. I assume those
without # at the beginning are enabled.

What I was thinking was to make a copy of it and edit out almost everything 
or
possibly better yet,.... create a new minimized one rather than trying to 
digest
the myriad entries .

What minimum should remain to permit secure web browsing and email  ?

What services am I overlooking with this idea that would possibly be a 
mistake  ?

Appreciatively,

Courtney
