Zmail and Gnu Emacs rmail interoperability

[shirley@parc.xerox.com (Mark Shirley)]

Has anyone successfully used both Zmail and Gnu Emacs rmail on the same babyl
file (e.g., by running Zmail on your workstation at work and rmail on a
terminal from home)?  I have tried this in the past and have been bitten by
slight differences in the file format so that Zmail couldn't parse all of the
message headers saved out by rmail.  Is some incantation necessary on either
side to get them to work together?  
Thanks,
