Hi Zimbra gurus,

I'm getting some messages about deferred e-mails from some servers.

Code:
... 450 4.7.1 Client host rejected: cannot find your hostname, [200.69.219.57])
I've read everything I could about this and I've reached the conclusion it was a reverse dns problem. So I asked my ISP to set it up. Today reverse dns is working ok Tools but some servers stills reject e-mail from mine.

Otro possibility I have read is a mismatch for the resolution of localhost.localdomain and my localhost ip address (127.0.0.1). When I do

Code:
 # nslookup localhost.localdomain
I get

Code:
Server:         200.69.193.1
Address:        200.69.193.1#53

** server can't find localhost.localdomain: NXDOMAIN
Do you have any ideas of what can cause this behavior?

Thank you in advance,

Pancho
