postfix per-domain transport

[edinn]

I started this previously on topic about external smtp server:

Quote:is it possible to make manual entry in postfix transport map, per domain, such as :
/etc/postfix/ispcp/transport:
domain.tld smtp:mx.google.com

(postmap that file and postfix reload after)

And ofc. to remove it from /etc/postfix/ispcp/domains

I tried that today, because mx entry was overwritten by dns template after subdomain addition, but gives me relay acc. denied.

Is there, perhaps, a list of entry types for /etc/postfix/ispcp/domains such as:
domain.tld vdmn_entry
