Zimbra Forums

My zimbra servers are configured to do DNS checking. As long as their is a ptr record of some kind it will accept. I agree that the ideal solution is the ptr record should match the A record. However, if the HELO response doesn't match the A record then the mail is rejected. It surprises me how many...

zone files show you have a domain called mail.domain.com. It appears to me that your domain is actually domain.com. But if you did not change your zimbra install it probably set up a domain called mail.domain.com. Did zimbra create a domain called mail.domain.com in the mail server? Is it listed in ...

the first time you ran - dig mail.domain.com any instead of dig domain.com any. This responded as though you have a zone file somewhere that has a domain called mail.domain.com. Of course your domain is domain.com. I don't know what DNS server has this but it would be the DNS server that is being us...

IMHO. I think you have a DNS problem and not an LDAP problem. I have tried my best to explain my take on the issue and I'm sorry that we aren't understanding one another. But I'm 99.9% sure it is in your DNS. But I could be wrong.

I'm saying zimbra tries to use mail.domain.com as the domain instead of domain.com. And that it appears that your original dig response shows you have a domain called mail.domain.com instead of domain.com. So it looks like your local DNS has a domain called mail.domain.com. Of course this is the ser...

Zimbra will try to use the FQDN of the server as the domain instead of just the domain name. This is why I ask. I have always had to change the domain on a clean zimbra install. Example. If the FQDN of the server is mail.domain.com Zimbra tries to use that as the domain instead of domain.com. In you...

did you tell it to change the domain from mail.domain.com to domain.com?

you don't have a DNS server on the local network that Zimbra is using to resolve its local IP. Which is paramount for split DNS. Are you running the Dig commands on the Zimbra server?

Why in the world would you set mynetworks to 0.0.0.0/8 ? You've practically opened up your server so world + dog can send mail through it. Actually I'm not sure any networks begin with 0. Maybe no one can send? Odd configuration either way.

config will generally have an internal DNS server that is probably not authoritative for your domain and that will contain only the private LAN IP's that Zimbra will use to resolve itself, including the NS records. Then you will of course have your authoritative DNS server that will have your public...
