I must admit I do not like formmail at all.
At one side I try to get rid of spam (and help others to get rid of their spam)
At the other side I help people creating their mail forms - and formmail can be 
quite an
obstacle:
- many versions include a referer check which would not really prevent a spam 
engine
from abusing it, but has a high probability of preventing flash-based mail 
forms to work.
- allowed recipients is a great feature if the users are happy with it, but it 
definitely breaks
any attempts at sending a confirmation mail

Now that allowed recipients is saved either in a text file on the respective 
domain, or in
a database populated by a control panel, I would probably change the script to 
disallow
cc and bcc transmitted from the web  - unless the site owner states the 
contrary in the
same file or database
A different point: I have been quite annoyed by people "testing" contact forms 
and typing
rubbish text and email into them, so I have made it a habit to verify that 
email addresses
are valid: no spaces, umlaut or accent characters, and a domain with an MX or 
at least
A record. Adding this feature to formmail might help all sites on a server; it 
does not really
prevent spam, although it might stop a few attempts ... but it does not block 
legitimate use
of formmail either
