Your reverse-lookup is not installed:
mehl:/var/qmail # dig @141.1.1.1 MX alphainter.net
;; ANSWER SECTION:
alphainter.net.         12H IN MX       20 mail.uunet.ca.

mehl:/var/qmail # nslookup 209.167.138.195 141.1.1.1
Server:  ecrc.de
Address:  141.1.1.1

*** ecrc.de can't find 209.167.138.195: Non-existent host/domain


I'm sure there is somewhere a RFC. The qmailprogramme on the other site
doesn't only look at the Name-IP of our site and verify's it - it looks at
Name-IP, too. You (or your Provider) didn't install the reverse.lookup.
This is a good method of stopping other people to spoof IP's.

I want to install that somewhen, too :-)
