multipart/alternative majordomo command processing

I just installed majordomo and it appears to be working well, with one
exeption.

Gmail sends a "multipart/alternative" message.  This is forwarded fine to my
list "playgroup".  However, when this is sent to majordomo@, majordomo tries
to act on everyline from "------=_Part_9009_6375454.1144880578766" as a
command.  In the reply it says invalid command.

I have tried installing stripmeme.pl.  This looks like it will work well but
can't seem to get sendmail to actually pipe through stripmeme.pl.

I've searched for some time now and am now ready to call for help.
(Most search results related to turning off html in list messages rather
than command processing.)

Any ideas?
