Hi,
According to exim4_passwd_client(5), my configuration should not work, but it
does (which is nice). I have the following router:
| xxlweb:
| debug_print = "R: xxlweb for $local_part@$domain"
| driver = manualroute
| senders = xxlweb.owsiany.pl
| domains = ! +local_domains
| transport = remote_smtp_smarthost
| route_list = * mail.xxlweb.owsiany.pl byname
| host_find_failed = defer
| same_domain_copy_routing = no
| no_more
And the following data in passwd.client:
| mail.xxlweb.owsiany.pl:porridge at xxlweb.owsiany.pl:my-secret-password
Where mail.xxlweb.owsiany.pl is an A record:
| ; <<>> DiG 9.4.1-P1.1 <<>> mail.xxlweb.owsiany.pl
| ;; global options: printcmd
| ;; Got answer:

But this IP addresses' reverse record is something else:
| ; <<>> DiG 9.4.1-P1.1 <<>> -x 81.169.178.178
| ;; global options: printcmd
| ;; Got answer:

The manpage says this will make the /etc/exim4/passwd.client lookup fail,
because it will look for alpha349.server4rent.eu, which is not there. But it
does work, and it seems exim looks for the name specified in the router.
This is with exim4 4.67-5build1 (ubuntu gutsy).
Is this just a "lucky" corner case? Or has something been changed recently, and
the bug can be closed?
