>Description:
Use OPTIONS feature in Makefile, therefore changed MESSAGEWALL_ALLOW_MULT_RCPT to
WITH_MULTI_RCPT but port stays backword compatible.
Added some useful patches from http://www.mulliner.org/collin/patches.php as
new options. Applemail vendor patch needs special handling because of new
"broken parameter" patch.
Port maintainer (opr at bsdaemon.be) is cc'd.
Generated with FreeBSD Port Tools 0.50

++.I Example:

++.I fakedbighost_reject=1,hotmail.com
++.br
++The value of a
++.B fakedbighost_reject
++line should contain a domain/host name. Incoming mail from this
++domain (the domainname is taken from the sending address) is checked against
++the "Received:" header fields. If NO match is found the assigned score is added.
++Use this with extreme care! And only use this for big sites that have their
++mail servers host name in the Received header line. If only the ip address
++is shown in the Received header (which is ok with rfc821) this feature is
++worthless. Many small sites are
++virtual which means the host name of the actual domain the mail belongs
++to isn't shown in any of the Received lines. Instead the name or ip
++address of the ISP hosting the virtual domain is in the Received line.
++And don't forget nearly all header lines can be forged.
++There can be multiple
