2.2a and postfix, what to put in virttable?

[Jev]

Hi again,

When using postfix to deliver to virtual mailboxes what should I put in 
the left hand data position?

If I do:



jev at example.com			jev at example.com
^-cyrus mailbox-^		^-postifx virtual-^


or

jev at example.com			jev at example2.com
^-cyrus mailbox-^		^-postifx virtual-^



As I understand it, postfix will attempt to resend any mails sent to 
jev at example2.com to jev at example.com, instead of attempting to deliver 
them locally to cyrus.

Slightly confused here,
TIA,
