[Bug 3302] New: Dynamic IP and Squirrelmail

http://bugzilla.spamassassin.org/show_bug.cgi?id=3302

           Summary: Dynamic IP and Squirrelmail
           Product: Spamassassin
           Version: 2.63
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Rules
        AssignedTo: spamassassin-dev@incubator.apache.org
        ReportedBy: japs@adm.ku.dk


We use Squirrelmail where a PC client through a web interface is able to submit
mail from the Squirrelmail server. No SMTP transport direct from the client.

However, Spamassassin assumes that the mail is generated by the client, which 
may have a dynamic IP address. Thus RCVD_IN_DYNABLOCK is set for the mail.
This is incorrect, the SMTP transport starts ar the Squirrelmail server.

The headers:

Spamassassin is running on proxy2, and I would expect it to check the IP
address of the sending server (and not a previous server).
