Emmanuel BILLOT via Postfix-users:
Is it possible to route messages on others servers based on numbers of
recipients ?
Ex :
if number of recipient <10 then relayhost is A
if number of recipient >10 and <50 then relayhost is B
if number of recipient >50 then relayhost is C

Perhaps postfwd can do this.
Otherwise, use check_policy_service with custoim policy server
that returns FILTER commands to route the message.
postfwd works as policy filter, so it can do that.
Note that in order to know number of recipients, you must call postfwd from
smtpd_data_restrictions or smtpd_end_of_data_restrictions
Also, using FILTER from smtpd_*_restrictions overrides content_filter
settings and can be only done once, and the last will be executed.
