Hi,
I have to route mail by /sender/ domain.
I found out about
sender_dependent_relayhost_maps =
pcre:/etc/postfix/sender_dependent_relayhost_map
with:
/.*@domain.de$/ special-mailgw
Works.
But: I observed postfix falling back to the MX for "domain.de" if
"special-mailgw"
is not feasable (down, timeout, responds with 5xx).
On the other hand I have two target mail gateways available.
I'd like to accomplish the following behaviour:
Dispatch mail from *@domain.de to special-mailgw .
If this doesn't work out,
dispatch mail from *@domain.de to special-mailgw-nr2 .
If this doesn't work out either,
enqueue and retry later .
(And never use the MX records for those addresses/domains).
TIA, Chris
