I've just discovered that my signed messages don't make it through to
my colleagues crackberries. Apparently something in the gateway drops
messages with attachments, or something.

Can EPG be configured via gnus-posting-styles so that I can turn it on
and off on a per-group basis?

Failing that, or may be irrespective of that answer, has anyone yet
constructed a tool that will send mail using the proprietary protocol
that Exchange uses?

                                        Be seeing you,
                                          norm
