permissions in sendmail

Hi

I have set sendmail up and the error I am getting is

fredm@nowhere.co.uk... Connecting to homer.nowhere.co.uk via relay...
220 homer.nowhere.co.uk ESMTP Sendmail 8.9.3 (PHNE_18979)/8.9.3; Fri, 21 Jul 20

Sounds like pitstop.nowhere.co.uk doesn't like mail emanating from fredm@nowhere.co.uk because this last address is not a valid subdomain. i.e. shouldn't it be from
.nowhere.co.uk?
Hence sender domain must exist!

Hope this helps
John

Thanks John

But I think the problem is in the relay server HOMER using DNS to resolve my new server and not being able to do so

Thanks

You might want to set up your relay server to have nowhere.co.uk defined in the /etc/hosts table; also if you are not using dns, rename /etc/resolv.conf ; and if you are using dns, you might want to set your nsswitch.conf as:

hosts: files [NOTFOUND=continue] dns

also make sure that your /etc/mail/sendmail.cw only contains the short hostname of your server and not its domain.

good luck
