I'm running Exim 4.34 on a Debian Woody Linux box.
The ACL that tries to verify the sender address always returns "remote
host address is the local host".
deny ! verify = sender
For example,
2004-05-28 15:42:17 H=nl-mail5.internet.com [64.62.164.185] sender
verify defer for <newsletter@???>: remote host address is
the local host
2004-05-28 15:42:17 H=nl-mail5.internet.com [64.62.164.185]
F=<newsletter@???> temporarily rejected RCPT
<mdm@???>: Could not complete sender verify
If I lookup in DNS - nl-mail5.internet.com, I get 64.62.164.185
If I lookup MX records for nl.internet.com, I get
nl-mail1.internet.com.
nl-mail2.internet.com.
If I look up the A record for nl-mail1.internet.com, I get
64.62.164.181
I can ping 64.62.164.181 ok.
That looks legitimate and coupled with the fact that every email
defers, leads me to believe that the problem is not on "their" end.
My DNS resolver seems to be working (I can ping other domain names and
my email gets delivered to other machines), and the Exim error message
is "remote host address is the local host" seems to indicate that my
DNS resolver is at least doing something other than timing out.

This Exim configuration simply drops email into a queue, where
Mailscanner verifies things and moves it to another Exim queue for
delivery.
If I comment this stanza out
deny ! verify = sender
delay = 59s
things work normally.
Scanning the mail archives, I don't see where anybody else has ever
complained of this error, so I must have screwed things up fairly
uniquely.
My understanding is that verify = sender will make sure that I can at
least return a bounce message to the envelope sender address.
I've tried some other variations like require verify = sender, without
any improvement.
Does anybody see where I am going wrong ?
Thanks
