           Summary: [RFE] tweak to improve trusted_networks guessing
           Product: Spamassassin
           Version: SVN Trunk (Latest Devel Version)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P3

        ReportedBy: quinlan@pathname.com


In addition to looking at the IP address, if the header matches certain
formats (especially QMQP and LMTP), then it should be possible to assume it is
internal.  NNFMP might be similar -- I'm not sure what protocol that is, it
only appears to be used by Yahoo, so I assume it's local-only.  QMQP is the
local protocol of qmail and LMTP is the local protocol used in postfix (and
maybe other stuff too, there's an RFC).  HTTP is another one to consider.

Some examples (I don't have many since I only see them for outgoing mail,
not incoming mail since I use exim which doesn't do this).
