[exim] RCPT ACL & local_parts

Hello,

I'm currently trying to reject mails that have specific, multiple local
parts and I wonder how to use multiple local_parts that are not used
alternatively?


While this matches any specified user:

 deny    message       = Message refused
         local_parts   = user1 : user2
         domains       = example.net

This could work if exim accepted two local_parts statements :-)

 deny    message       = Message refused
         local_parts   = user1
         local_parts   = user2
         domains       = example.net

Any hints?
