Hi
Apologies for the length of the email!
I'm running Exim 3.16 on Solaris 7. I have seen the following error on
my mailhost when the sending host is aliased in the dns:
<IP address> does not match any IP address for <fqdn>
Here's a real example from my mainlog:
2000-11-27 09:53:12 connection from [129.215.144.8] refused
(129.215.144.8 does not match any IP address for rhymer.cogsci.ed.ac.uk)
I did an nslookup:
[root@server log]# nslookup 129.215.144.8
Name: rhymer.cogsci.ed.ac.uk
Address: 129.215.144.8
Then, I used dig and saw that they're using aliases:
[root@server log]# dig rhymer.cogsci.ed.ac.uk
; <<>> DiG 8.1 <<>> rhymer.cogsci.ed.ac.uk
;; res options: init recurs defnam dnsrch

I looked in the exim list archive and saw that Phil Hazel suggested
testing with exim -bh <IP address>. One of the IP's will resolve OK, the
other IPs fail. Full outputs for each IP are at the foot of this
email...
There's no wildcard in my hosts_reject and rhymer.cogsci.ed.ac.uk is not
in the RBL. Is there some directive that I've missed?
Thanks
Paul
