Can't receive email from GMAIL

[rayot]

Hi all, btw i'm new here.

I installed Zimbra on my CentOS 5 machine and I'm able to send / receive email from my domain. I can also send email from yahoo, gmail etc. but the problem is I can't reply from my GMAIL account to my local domain account.

Here's the message from GMAIL:

Technical details of permanent failure:
DNS Error: Domain name not found

Here's my system info:

cat /etc/hosts

# that require network functionality will fail.

host `hostname`
paulocabalo.com mail is handled by 10 centos5.paulocabalo.com.


I apologize for the long post. I hope someone could help me with this one.

Thanks!

That error would seem to be correct, according to the following output you have no DNS records for your domain (I'm assuming that you've posted the real domain name above?):

Thanks for the reply pheonix.

My current setup would be:

ISP -> Dynamic IP -> Router -> CentOS machine.

The domain posted is the one I created locally for my test server. Is there any workaround on my current setup? I am really a newbie on this one. sorry for the trouble.

You need public DNS records for your domain and they should point to your server. I must, however, caution you that a dynamic IP address is not the best environment to run a mail server as you may get 'listed' as a spammer.

I see. So I don't have any choice then? heh.

I'm just testing Zimbra on my home network just to play around with its features.

Very well then. Thanks for the info.

No, not if you want to receive mail at that server.
