Hi all,
i've set in my exim.conf host callback:
sender_verify_hosts_callback = *
sender_verify_callback_domains = *
I've noted that exim try to verify incoming mail back to the same host
where have received it...
exim_mainlog:
2002-04-22 09:27:42 16zYEf-0004Fj-00 <= user1@???
H=(mail5.cs.interbusiness.it)
exim_rejectlog:
2002-05-20 17:54:22 179pUM-0000jc-00 rejected from
(mail5.cs.interbusiness.it) [151.99.250.40]: temporarily unable to verify
sender address <user1@???> (try later)
see DNS mx query:
> qnt.it
Server: ases01.ases.it
Address: 192.168.200.1
Non-authoritative answer:
mydomain.it MX preference = 10, mail exchanger = mail.mydomain.it
mydomain.it nameserver = dns2.nic.it
mydomain.it nameserver = dns.mydomain.it
mail.mydomain.it internet address = x.x.x.x
dns2.nic.it internet address = 193.205.245.8

Why exim is calling back the sending host? It should callback host in DNS
MX query....
I can use one mail server for incoming mail and another one for outcoming mail.
