Transport map

Hi all. Is it possible to have a transport map with a regular expression? What I want is to use an external relay server for all the emails to be delivered on Yahoo domains (eg, yahoo.com, yahoo.co.uk, yahoo.es, ecc). If it is possible, how can I implement this? Thanks. -JK

I would like to reduce the mysql transport retry time (or perhaps the proxymap retry time?), is there a variable that I can tweak down to reduce the time between retries of mysql transport connection losses? I'm using mysql for transport_maps and virtual_mailbox_maps. transport_maps = proxy:mysql
