    Hi --

    I'm trying to get masquerading to work with Sun's sendmail 8.11.7p1+Sun/8.11.7, Solaris 8.

    It works fine when I use any existing name for host.domain -- except of course the name I want to use -- using the following statements in sendmail.mc:
        MASQUERADE_AS(`host.domain')
        FEATURE(`masquerade_envelope')
        FEATURE(`allmasquerade')

    I want to masquerade as biocomp.doit.wisc.edu. The machine name is biocomp2.doit.wisc.edu. (I want to be able to have a biocomp3.doit.wisc.edu someday, and continue masquerading as biocomp.doit.wisc.edu.)

    But what I see when I trace it in verbose mode (sendmail -v) is:

    >>> MAIL From:<jwinkle@biocomp2.doit.wisc.edu>

    biocomp and biocomp2 resolve to the same IP address. Receiving mail addressed to biocomp.doit.wisc.edu works fine by using /etc/mail/local-host-names.

    Any ideas how to get this working as desired? I will summarize if/when I get it working. Other info that might be useful:

    My /etc/hosts looks like:
        #
        # Internet host table
        #
        127.0.0.1 localhost
        128.104.22.200 biocomp2 biocomp2.doit.wisc.edu mailhost loghost

    Here's the output of '/usr/lib/sendmail -bt -d0 </dev/null':
        Version 8.11.7p1+Sun
         Compiled with: LDAPMAP MAP_REGEX LOG MATCHGECOS MIME7TO8 MIME8TO7
                        NAMED_BIND NDBM NETINET NETINET6 NETUNIX NEWDB NIS NISPLUS
                        QUEUE SCANF SMTP USERDB XDEBUG

        ============ SYSTEM IDENTITY (after readcf) ============
              (short domain name) $w = biocomp2
          (canonical domain name) $j = biocomp2.doit.wisc.edu
                 (subdomain name) $m = doit.wisc.edu
                      (node name) $k = biocomp2
        ========================================================

        ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
        Enter <ruleset> <address>

    Thanks!
