#5 Spamcup for mailsc.spamcop.net without code= logon.

[andrew morton]

As per the discussion at:
http://sourceforge.net/tracker/index.php?func=detail&aid=990590&group_id=85670&atid=576915

Here's my version of the spamcup script. Changes include:
* removing the old password-less code logons.
* adding a -m switch to select the mailsc.spamcop.net
server.
* code tidy-ed by perltidy.
