The only other concern is to make sure that the table in question
is (typically indirectly) listed in $proxy_read_maps.
Everything in main.cf worked out of the box with proxy:mysql:/
However when i tried to add it to master.cf for submission i got the
error you talking about.
127.0.0.1:submission inet n - n - -
smtpd
...
-o
smtpd_sender_login_maps=proxy:mysql:/etc/postfix/mysql_sender_login_matching
I checked postconf -d and the map is included, but it looks like when
running under submission that default isn't carrying over. I tried to
add it to the submission trying both of
-o proxy_read_maps=$smtpd_sender_login_maps
-o
proxy_read_maps=proxy:mysql:/etc/postfix/mysql_sender_login_matching
And neither worked. I still got the error saying request unapproved for
table. What is the correct way when using proxy in a master.cf
submission line?
