virtual domains in Cyrus 2.2

[marc.bigler at day.com]

Hello,

Is there any documentation around on how to use the virual domains feature
which is available in Cyrus 2.2 from CVS ? If no, could maybe someone tell
me how do I enable this ?

Another question regarding this feature, from the MTA point of view does
that mean that the MTA needs to pass the account name as the full email
address (user at domain.tld) ? I am asking this because then I will need to
change my virtualuser table and such, right ?

Thanks
Regards
