As long as you're aware of the vulnerability of this technique - sender
addresses are easily forged - you can accomplish what you want with an ACL
fragment (in the rcpt acl) like this:

deny message = Your mail is unwanted
senders = lsearch;/file/of/banned/senders
recipients = user@example

Note that this doesn't devnull the mail, it denies it at SMTP time - to
actually devnull (ie accept normall then silently discard), use 'discard'
instead of 'deny'.
