Subject:[courier-users] DNS lookup Failure on 0.35.1Actions...

Hi all,

We used since now ten month Courier on a Solaris 8 system (release 0.35.1). All run fine since because we only use courier to send out message to recipient.

Recently, we would like to use it to receive message from outside. And we discover it don't accept to receive mail if in the from field of the message, the domain part of the sender's adresse can't be resolve on the DNS.

Below a dump of log :

Apr 4 17:58:36 S0003010 courieresmtpd: [ID 702911 mail.error] error,relay=10.0.161.19,from=<thie@free.fr>: 417 DNS lookup failure: free.fr. Try again later.

The server we have act as a mailhub from a subdomain. It's configured to resolve on DNS to send and if it can't, to relay to the main mailhub in front of us.

Does it is normal, and could we bypass this problem. I hope so, may be it's a configuration mistake of us ? Does anyone have an idea ?

Thanks in advance for your help
