Hi DU Admins
We have a central mail server and all our other machines are running
as sendmail null clients. The problem is that with sendmail 8.9.1's
anti relaying feature the server refuses to relay mail from the clients.
The null clients don't add the domain to the sender's address
and the server rejects messages with this error:
... reject=553 <user>... Domain name required
I tried adding the option `FEATURE(always_add_domain)' but this
doesn't work for a null client. The domain is added by ruleset 5
which doesn't apply to null clients.
At the moment I'm using `FEATURE(accept_unqualified_senders)'
on the server to get around this problem but I'm worried this might
open a hole for relaying.
Does anyone know of a way to get the domain appended to sender
addresses from a null client? Is the accept_unqualified_senders
feature a serious risk?
Just to avoid any possible confusion:
All the null clients are listed in the servers sendmail.cw file.
I've set `FEATURE(relay_entire_domain)' in the server's config.
I also know about the relay domain file and the access_db file but
I don't think they're relevant in this case since the error being
reported is no domain on the sender's address.
Thanks
Ian
