Hi,
I have a set of domains for which I am relaying mails through my
server. The final destination server for some of these domains are
always available (connected to the internet all the time and powered
on) for which I would like to implement recipient address
verification. There are some other destination servers which are not
available all the time (switched off during the nights and weekends)
for which I would like to maintain relay_recipient_maps so that I can
accept and queue the mails till the host is back online.
I have successfully configured both types of recipient verification
individually. Now I would like to have these working on the same server.
I've been using smtpd_restriction_classes and check_recipient_access to
apply different rules to different domains.
You place the domains that are always online in one group, the domains
that are not always online in a second group, and then place
check_recipient_access at the bottom of your smtpd_recipient_restrictions.
smtpd_restriction_classes =
always_online_domains,
sometimes_online_domains
smtpd_recipient_restrictions=
...
check_recipient_access hash:/etc/postfix/domain_to_classes_mapfile
/etc/postfix/domain_to_classes_mapfile:
example1.com always_online_domains
example2.com sometimes_online_domains
Unless someone comes along and says its a terrible thing to do to a
server, it works for me!
