Yaws source has a functional SMTP client module...

For me the main problem is the flat module namespace - it is very
hard to find the correct module. This could be solved even without 
any real changes by adding a "category" header to modules.

-module(foo).
-category([bar]).

Now just make all documentation generation tools look for it and 
most of the problem is solved. As for various small usefull things
a standard way of creating hex presentations of strings/binaries 
would be nice like:

hex(Bin) when binary(Bin) -> hex(binary_to_list(Bin));
hex([]) -> "";
hex([H|T]) -> 
	[A,B] = if 
		H == 0 -> "00";
		H < 16 -> [$0,element(H,{$1,$2,$3,$4,$5,$6,$7,$8,$9,$A,$B,$C,$D,$E,$F})];
		true   -> erlang:integer_to_list(H,16)
	end,
	[A,B|hex(T)].

Yaws has something similar too.

Sha1 checksums would be nice.
