Hm... in one case you get one more Received/Delivered-To pair. And 
what about the envelope sender? In general, maildrop allows to plug 
any forwarding policy that may be relevant, e.g. spam-filter before 
forwarding, required DNSBLs, SPF checks, et cetera. See also:

Apparently, those issues are less relevant when configuring two or 
more synchronized servers, e.g. using courierldapaliasd and IMAP/POP3 
aggregator proxy. In such cases, any "forwarding" should probably be 
considered just a delivery mechanism. However, I'm not sure what 
happens if a message forwarded to multiple users hits quota limits for 
just some of the recipients.
