I'm trying to setup load balancing across a cluster of relays for a

Hi,
Stuck again.
Using
smtpd_end_of_data_restrictions = check_policy_service inet:127.0.0.1:8822
smtpd_policy_service_default_action = DUNNO
I get:

table inet:127.0.0.1:8822 has entry with lookup table:

Hi all,
I found that check_policy_service works (maybe*) in
`smtpd_end_of_data_restrictions =`. So I'm guessing it might work in
any *_restrictions configuration.
(*still having some issues getting this to work as expected, but I'll
come back here if I get stuck)

Hi,
I want to provision load balancing for my relays. The catch is that
there is already some customized routing in place based on recipient
domain and large block lists. These are currently handled by a
transport map.
I would prefer not to implement 2 layers of relays. If this were

I think you really need to look at multiple log entries to discover that, e.g.

Hi,
In my previous question [1] Viktor Dukhovni suggested

as a means of preventing active queue congestion.
This took me down a bit of a rabbit hole looking at SMTP Access Policy
delegation and tcp_tables

Hi,
I look after a SAAS site where customers can send emails to their own
domains. At times some of our customers can initiate sending of large mail
volumes - which can swamp the active queue.
