Urgent help - exim problems

[vashti]

Hello all

For some reason, email has stopped working (sort of):

1. email from an account on the server to another account on the server can be recieved and sent without problem.

2. email from an account on the server to an email account *not* on the server results in:

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'recipient@not-on-problem-server.com'. Subject 'test', Account: 'mail.email-on-problem-server.com', Server: 'ip.ad.re.ss', Protocol: SMTP, Server Response: '451 Temporary local problem - please try later', Port: 25, Secure(SSL): No, Server Error: 451, Error Number: 0x800CCC79

3. email from an account *not* on the server to an account on the problem server is not received at all:

Final-Recipient: rfc822;user@email-on-problem-server.com
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;550-Verification failed for <sender@not-on-problem-server.com>
550-unrouteable mail domain "not-on-problem-server.com"
550 Sender verify failed

What have I done to try to remedy this:

1. Searched these Forums for hours
2. /scripts/exim4 (no change)
3. rm exim.conf and then /scripts/exim4 (no change)
4. /scripts/exim4 again (no change)

I don't know what more to do now.

I am willing to pay by Paypal for resolution to this, as I am 100% stuck. please help!

I have also tried

/scripts/restoreeximtodefaults (again no change)...

Help! Paypal not a problem!

[vashti]

I have now also rebooted the server. This has not fixed it either...

FYI, I am running:

WHM 9.1.0 cPanel 9.1.0-S73
RedHat 7.2 - WHM X v2.1.2

Sounds like a dns problem, not a mail server problem.

Make sure resolv.conf is set correctly.

Hi elleryjh, thanks for that. I have tried this and it looks good - I have two servers actually and the one that is OK (accetping/sending emails etc) has the exact same resolv.conf settings as the one that is not OK...

Any more ideas would be great please!

what happens when you run the command

That means you can't get to google. Definetly a dns problem.

Probably best to contact your data center for this problem.

Thank you for your help, I will post back when (if) I can find resolution to this.

That is probably the problem. The Server that is not OK should be using it's own Base IP, not one for another Server.

Change resolv.conf of the problem Server to look like:

nameserver 127.0.0.1
nameserver (enter Server BaseIP)

Restart Bind and you should be OK.

/scripts/restoreeximtodefaults

This is what finally fixed this for us. After 4 hours of working my way through every suggested fix for this issue '/scripts/restoreeximtodefaults ' finally did it.

This appears to be an ongoing issue. We have just updated to 9.8.0 C13 and all our clients emails started getting this 451 error, which first appeared as a Horde 'Auth.php' error.

Anyway, all is ok now.
