Check your pointer records. You can also start here testing you mail server to make sure nothing is wrong.

Hi Victor,

Your first step was the correct, disable IPV6 in Exchange 2010.

Please make sure that your sending IP has a PTR record (i.e., a reverse DNS of the sending IP) and it should match the IP obtained via the forward DNS resolution of the hostname specified in the PTR record.

Regards
Valentina

HI Victor,

You are using MX record or a smarthost to send emails?

If you are sending with MX record, you should be sure that you have static IP.

Hi,

Mx records are used to receive mail and pointed to external spamfilter.

I don't use smarthost, the vm server is located in a datacenter and uses dns to find other mail servers.

Strange problem.

Commented:
HI Victor,

Yes very strange.

After you disable IPV6.

Did you restart the server?

No, it was during the day that i made de registery change.
I send a test mail to my own gmail and it worked fine so din't think about it anymore.

I give it an reboot and let you know.

Commented:
HI Victor,

Please tell me after rebooting the server.

It looks that a reboot fixed the problem.

It's logical that you need a reboot after reg change but not mentioned in the instructions desabling ipv6, so i dint try that one.... :-(

Many thanks

Best regards
