Have you got the proper reverse DNS and MX records set up in the public DNS for your mailserver? A lot of things can result in a refused connection but that's definitely a common reason.

I have two entries in /etc/hosts file:
127.0.0.1 localhost.localdomain localhost
192.168.1.167 mail.centroviaxes.com mail

i have all ports open in my router (25, 110, 80, 143, 7025, 443, 7071) redirecting to 192.168.1.167

i have opensuse 10.2 and firewall is off. My zimbra is 5.0.5 open edition.

i send mail to my gmail account without any problem. But if i send a mail to my admin@centroviaxes.com account, in my zimbra's server mail queque appears that message as error (connection refused my public ip).

i have this entries in my domain:

centroviaxes.com MX 10 mail.centroviaxes.com
mail.centroviaxes.com MX 10 mail.centroviaxes.com
centroviaxes.com A my public ip
mail.centroviaxes.com A my public ip

what is the problem?

You do not have any reverse DNS and that's likely causing you a problem.

nslookup 212.170.101.12
Server:         192.168.1.6
Address:        192.168.1.6#53

** server can't find 12.101.170.212.in-addr.arpa: SERVFAIL

and this report:

ou will probably have to contact your ISP and get them to create a reverse DNS for your IP address.

I have been looking this and my isp doesn't support reverse dns because spam.

How can i configure zimbra without reverse dns?

That is nothing to do with Zimbra configuration. It's other mail servers that check if you have a reverse DNS, if you don't they give your mail a spam weighting or refuse to accept mail from you.

If this really is your problem then the only alternative would be to relay mail through your ISPs mail server.

Huh? That makes no sense. Reverse DNS is the world's way of double checking that if they get mail from somedomain.com, the IP address from which the mail came really belongs to somedomain.com. Spam usually doesn't come from valid ips on valid domains so it's a pretty reliable check. I can't think of any reason that implementing RDNS would increase spam; if that's the position of your ISP perhaps you need to consider a different one. . .
