Hello All and John,

Yes this is the same response I got from dns.uleth.ca and
dns2.uleth.ca ,
>So 142.66.73.2 isn't identifiable as being part of *.resnet.uleth.ca (or,

Where can I find the relevant information about this in the Exim
Docs ?

I think that I will implement this as soon as I get the basics
working again.

Okay this is certainly very good to know. But it seemed to work
up till yesterday. Hmmm ... maybe the DNS admin has done something.

Nope didn't do anything different from yesterday.

Nope same answer as above.

Probably where the problem lies. I wonder why it took so long
before Exim gave me this error message as its been working fine before with
this same naming issue.
Unfortunately I am not the DNS admin (I wish I were) but it seems
that you all are right, I checked these settings against an internal dns
server and it seems to find the IP address and the associated information
correctly. I have e-mailed the DNS administrator about this stuff,
hopefully he will respond soon. Here is what it should look like, no ? Or
somewhat like it. It was the correct information before they tinkered with
DNS a few weeks ago. I hate it when the rest of us aren't told what is
happening.
Server: ratbert.online.uleth.ca
Address: 142.66.33.100
Name: rez256.reznet.uleth.ca <---- exim gets H= (rez256.uleth.ca)
[142.66.73.2]
Address: 142.66.73.2
So something is wrong DNS wise. Thanks to all those who did
respond to my problem.
Cheers,
Aly.
