+##### SMTP UUCP Mailer specification
+#####
+##### This mailer sends UUCP traffic over an SMTP connection.
+##### Obviously, we only want to do this with UUCP hosts with
+##### whom we have SMTP connectivity. The idea here is to
+##### avoid having to double queue (once for sendmail, once
+##### for UUCP) when there's no need. Since we need to
+##### preserve uucp-ness (e.g., bangs), we use the UUCP mailer
+##### rewriting rulesets.
