Once upon a time, I had a Perl script I used as a Mutt hook that did 
exactly this (well - it always said "yes").  Unfortunately, I can't seem 
to find it now.  I'll look at old backups, but I've been using a 
calendar for a while now.

As far as I remember, it wasn't all that difficult: read in the original 
ics file and send it back with your name filled in, as Sam wrote.  I 
seem to recall that Microsoft Exchange was quite picky about the MIME 
type of the attachment but other than that, it was straightforward.

I'll see if I can find my script somewhere.  It should not be too 
difficult to turn it into a MailMate bundle.  Might be quicker to just 
write a new script.
