Hi,

I have got this error message "warning: 192.168.1.2: address not listed
for hostname margoullat.memoria.fr"
I read in "http://www.postfix.org/faq.html#paranoid" that this error
message is due to wrong DNS entries. I checked my DNS and I do have a
PTR and an A record for that IP address.
so what could be wrong in my config?

Cheers
