I want to set up a server rule that will auto reply to
messages and include new contact information for me.

I've tried setting up an "out of office" rule but can't
embed a vcf file in the message.

I've then tried a general rule with a template (not
addressed to anyone but with a message and vcf) and turned
it on and when I check it I don't seem to get a reply.

Can you advise how to do this so people who contact me
after I leave will get my new vcf file automatically?
