sendmail: Sender domain must resolve

[Roberto Gallis]

Hi all,
I use a smart relay to send out mail from my hp-ux 11 system.
But, when I have to receive mails, my sendmail return the following error:
Sender domain must resolve
and the mail is not sent to the final mailbox
Anyone can help me to configure sendmail?
Thank you all
Regards

Roberto

Hello Roberto,
this is not a problem of your sendmail, but of the receiving mail-server. Some are configured to reject mails where an reverse AUTH request fails.
Most times this query is not very intelligent. You should put in a valid E-Mailadress as a "From:" field, and it should work.

Hmm, just re-read....

I missunderstood. Can you set up DNS-client on this box, so it can resolve the e-mail-adress to the sending host ?

I unfortunately do not know the switch to disable this auth-behavior.

Sorry

Hi,
I think is not a problem of the sender (which use dns).
I tried to
telnet myserver 25
and give manual command to send a mail... the response is Sender domain must resolve
So I think is my sendmail have to resolve destination (that are all local mail to user)
