[Mimedefang] Sendmail config (slightly OT)

    Yes.  I have one master incoming MX which then forwards to the final 
servers:

    Master MX: serpico.pcraft.com        )
    Recipient1 server: spool.pcraft.com  ) - These three are different
    Recipient2 server: swiri.yeehaw.net  )   machines on the network

    On the MX server:
    =================
       Sendmail's configured with:
          local-host-names, virtusertable, mailertable
          genericstable, generics-domains, access
          blacklist_recipients, milter
          bl.spamcop.net, relays.ordb.org, list.dsbl.org, multihop.dsbl.org
          MIMEdefang, SpamAssassin, ClamAV

       And there's no local delivery on this machine other than cron 
sending mail to root, which automatically gets forwarded to the actual 
spooler.

        /etc/mail/mailertable
           pcraft.com      esmtp:spool.pcraft.com
           yeehaw.net      esmtp:swiri.yeehaw.net
           ...

        /etc/mail/local-host-names
        /etc/mail/generics-domains
           these files have ONE entry in them, and that's the MX's FQDN

        /etc/mail/virtusertable
           this file contains TWO virtual users, both are for root.  ALL 
incoming e-mail gets denied or accepted based on each individual 
(recipient) server's virtusertable.  This way I don't have to maintain 
one master file for everyone's server.  They can do that themselves.

        /etc/mail/relay-domains
           Contains every single domain hosted across our entire network

        /etc/mail/access
           this file contains blanket domains and other addresses that's 
been blocked everywhere.  For example, all the recipients servers at 
some point blocked 'hongkong.com', so I put it in the master MX so it 
gets stopped at the door instead of traversing the network back and forth.



    On spool.pcraft.com
        Sendmail's configured pretty much the same exact way, except for 
milter, MIMEdefang, SA, and ClamAV.  The files are just used differently 
(or not used at all.)

        /etc/mail/mailertable -> empty

        /etc/mail/local-host-names
           This file now contains all the possible domains this machine 
accepts (final) e-mail for

        /etc/mail/generics-domains
           One entry, the machine's FQDN.

        /etc/mail/genericstable
           This contains all the translations for each user on the 
server, so that outgoing e-mail will have the proper domain name 
attached to it.

        /etc/mail/relay-domains
           Contains the local domain, and people outside our network 
that use this machine as an [E]SMTP machine for outgoing e-mail (only 
because I've been too lazy to setup pop_auth or any other mechanism to 
authenticate through.)
