smtp-auth from exim4 client to exim4 server

[Rainer Dorsch]

Hello,

I am not sure if this is a knows exim4 issue, therefore I mail before I open a 
bug report.

I am running smtp-auth from an exim4 client to an exim4 server. The issue is 
on the client side.

I found in the man page of exim4-config_files, that hostnames in passwd.client 
need to have a reverse dns entry. But even with that, I do not get 
authenticated correctly:

From the server (exim4) log:
2007-09-16 00:22:37 H=f051098206.adsl.alicedsl.de (silverboxy) [78.51.98.206] 
F=<root at bokomoko.de> rejected RCPT <rdorsch at web.de>: relay not permitted


When I use the hostname with a reverse dns entry as smarthost (I use debconf 
to modify the smarthost value), I get it working:

2007-09-16 00:25:10 cram_md5_server authenticator failed for

I was debuging here for some hours until I found that out. If it is known 
(what I assume), what about adding it to a prominent place 
at /usr/shar/doc/exim4 ?

Many thanks,
Rainer
