Milter-greylist

Hello,


I have some troubleshootings with some sub domain.


For example :

Jan 15 11:29:07 messagerie sendmail[14116]: l0FASuun014116:
ruleset=check_mail, arg1=<stardieu@...>,
relay=mail.reprox3.com [195.25.249.156], reject=553 5.1.8
<stardieu@...>... Domain of sender address
stardieu@... does not exist

When you try to do a dns report on this domain you have that answer :

http://www.dnsreport.com/tools/dnsreport.ch?domain=orbite.toshiba.fr

However toshiba.fr exists and is correctly define.

Have you got an idea to correct this without whitelisting this toshiba
address or declare orbite.toshiba.fr in my host file (or on my DNS
server) ???

I know that the domain's checking is to avoid spam but for some sub
domains, it's not spam. So, should we try to disable anti-spam
Milter-Greylist control on sub domain with regExp ?? Or is there a
best solution ?

Thanks.
