All emails seems to be rejected as:
sender verify defer...

Any advice? I have not done any changes to the server.

Kind regard,
Claes.


Extract from log.

Several of these log entries point to problems in DNS resolution from your server. You should probably log in through a shell and check the DNS servers in /etc/resolv.conf to see if they're actually reachable and actually can resolve the domains and the IP#s.

"Message too big" means exactly what it says.

There appear to be a few other miscellaneous errors as well, but I really don't see a pattern.

Hi Jlasman!

Thanks for your advice. The message too big, I got. It's the "sender verify defer for..." I'm worried about.

The resolv.conf file has these entries:

domain layeredtech.com
nameserver 216.39.65.6

Layeredtech is where my server is. Would this seem plausable? I certainly haven't changed these settings and it has been ok earlier.

Could network problems influence on this?

All advice appreciated, because I'm at a loss to figure this out.

Kind regards,
Claes.
 
Changed to a different IP with layeredtech. Seems they may have changed local DNS and kept it a secret.

What will have happened to receject emails? It wasn't returned to sender when I tested. Has it been lost in cyberspace?
 
You can safely remove the line that starts with "domain"; it's useless in a shared server; what it does is adds a domain name to any hostname specified without one before looking it up in DNS.

It's doubtful that if you or any of your customers tried to send something to a hostname and forgot to add the domain name, that your hosting company would be the right one. So just delete it.

You should probably specify at least two nameservers with two nameserver lines. Do you run the nameserver on your own DA system? If so you should try using it to see if it resolves external domains. Try:

dig @127.0.0.1 nobaloney.net

and if it works, then add the line:

nameserver 127.0.0.1

to the top of the resolv.conf file to use your own nameserver first when resolving names.

dig with localhost worked like a dream. I have added that to the file.

Thank you so very much for your advices! Send me your address and I'll have chocolates delivered on your door. If not, this sort of help exactly the sort of thing that will give you the upper hand on the judgment day. I'm sure.

Thanks for your great reply :) :) :) .

I love chocolate, but it's not good for me, and I discourage people from sending donations, since I'm not shy to ask for money for work when I want to :D .

If you really want to, you can pass my help forward (as in the movie "Pay It Forward").

(Note the above link does NOT pass a referral to Netflix; if you click on it you'll read about the movie but if you subscribe I won't get a cent. Which is the way I want it.)

Be creative, spend an hour on Christmas serving food to the needy or something :) .
