[ic] same pgp key for multiple users on mail list?

[interchange-users@icdevgroup.org (Dennis Chen)]

Hi all,

Good thing is I got the gpg to work on my 4.8.6/7.3 Redhat to work on MY
machine.
I created the keys on my local windows box and imported into the server so
this part
works fine as I get the email and can decrypt the credit card info.  The
thing is our
order_fulfillment@mysite.com gets directed to 4 people from our exchange
server so 
I thought importing the key for order_fulfillment@mysite.com onto their
windows box 
and they sign it will work....but it does not.  They imported the key and
signed it, but 
still says that the order_fulfillment@mysite.com key is invalid when they
get the order email.  
I've read through the docs and followed directions but am kinda stumped.

I believe it's not necessary to create another route in catalog.cfg as the
email this is just 
a single email but is being redirected to the people on that email list.

Thanks!
DC
