Oggetto: [Exim] [sleclerc@actionweb.fr: Bug#119747: Problem with host_reject_recipients and mysql]
I folks!

I'm directly answering on this.

I made the try again. I'm using v3.32.

Yes, my host_reject_recipients list contain a mixture of IP and full name
host. I don't want host_lookup because too many hosts haven't reverse DNS
entry.

It seems that the +allow_unknown is not validated with this function and the
MySQL lookup is stopped.

From my understanding, I should have:

Message from 1.2.3.4  -> host_reject_recipients (1.2.3.4, ns.netkobe.gr.jp)
                      -> refused


With +allow_unknown, it should pass the test. Or in fact, no.

What do you think of that?

Stef...




1.2.3.4 and ns.netkobe.gr.jp are in the mysql database...


This first one is without host_reject_recipients setup:
# host_allow *
# host_reject_recipients = "+allow_unknown : mysql;MYSQL_REJECT_HOSTS"
