In config, I've defined allowed relay_domains
/main.cf
...
relay_domains = DDDD1.com
DDDD2.com
...
DDDDn.com
and also use
transport_maps=lmdb:/usr/local/etc/postfix/tranports
where currently, each relay domain is
/transports
...
DDDD2.com relay-vpn:[internal.DDDD.com]:12345
DDDD1.com relay-vpn:[internal.DDDD.com]:12345
...
DDDDn.com relay-vpn:[internal.DDDD.com]:12345
...
Can the relay_domains array itself be correctly used as a lookup in a lookup
table?
I'd 1st guess that some form of regex table could be amenable, in effect
/transports.pcre
...
/$relay_domains/ relay-vpn:[internal.DDDD.com]:12345
...
?

body patterns can certainly be referenced as match variables ( ${1}, ${2}, etc
), but I've so far missed any mention of use of main.cf data.
Of course there are other ways at this ... putting the relay_domains in an SQL
DB, and using an SQL lookup , etc.
The reference to 'flatfile' main.cf's data would simply be, in this case,
convenient.
