Hi, not exactly this.. i'll write more details...

I've 2 mta and 2 backend servers with cyrus.
On mta i'm using virtual_maps to expand aliases, forwards and so on,
ale relay_domains which shows me which domain in on cyrus, and which
mail should by send by relay_transport to backend. Any other mail is
send through smtp to internet.

In case of big systems where are thousends of domains on backend is it
difficult and slow
to keep all in relay_domains file or in some kind of database, as
PostgreSQL or MySQL.

Is it possible to such construct configuration to use query used by
virtual_maps to match mail as to be relayed throught relay_transport ?

Thanks
AK
