    Default Domain Problem

    I must preface this question by saying other then the problem I am having now, I love zimbra. The interface is very clean and it runs pretty well. So here is my problem. I have a the server setup on FC3 and under my server settings when I have "DNS Lookup enabled" I can not receive any email, but I can send to all domains. So, when I disable "DNS Lookup enabled" I can recieve all email and I can send to most domain's but I can't send to hotmail.com for example. In the zimbra.log I get the following error....

    07C388B4238: to=<xxxxxxxx@hotmail.com>, relay=none, delay=33809, status=deferred (connect to hotmail.com[64.4.33.7]: Connection timed out)

    So it looks like I am resolving the domain name, but I don't know if I am looking the their mx record correctly. This error is not caused by a busy server on their end because when I am setup like this I can never get through.

    When I have "DNS Lookup enabled" I get the following error...

    Oct 13 06:38:20 mail1 postfix/lmtp[11677]: D059D8B4223: to=<xxxxxx@grassyassamoeba.com>, relay=none, delay=190, status=deferred (connect to mail1.grassyassamoeba.com[68.76.xxx.142]: Connection timed out)

    Any help would be greatly appreciated. Thanks

    Default

    Seems like you have an incorrect Mx or DNS rocord for your domain. Does DNS (not just your /etc/hosts) have the correct IP pointing to your Zimbra box.

    My guess on hotmail not working when you disable DNS is that you send the internal IP of your server rather than the internet IP. So Hotmail drops your connection(or don't reply) when they try to do the reverse DNS on you SMTP chat. I think Yahoo and AOL also do reverse DNS on SMTP chat so you could try sending to one of them to validate or disprove my theory.

    Default Rundown of my setup

    When I send an email to any of those domains it never gets through. Here is a little more info. Maybe I have something set up wrong, but I used to run postfix with squirrelmail as a frontend without any problem. For DNS I am using a third party called domain direct and my setup is as follows....

    A record
    grassyassamoeba.com
    68.76.252.142
    *.grassyassamoeba.com
    68.76.252.142
    mail1.grassyassamoeba.com
    68.76.252.142

    Mail Exchanges (MX Records)
    mail exchange ---- hostname ---- Preference
    grassyassamoeba.com ---- grassyassamoeba.com ----- 10
    mail1.grassyassamoeba.com ----- grassyassamoeba.com ----- 20

    Under zimbra
    -------------
    servers
    mail1.grassyassamoeba.com

    service hostname
    mail1.grassyassamoeba.com

    webmail mta
    mail1.grassyassamoeba.com

    enable dns lookup - disabled

    domains
    grassyassamoeba.com

    Once again thanks for any help.

    Default Update

    From what I have found the problem either has to do with a PTR record or SPF, has anyone ever set up either of these that could give me a little help. It looks like this is AOL's attempt to block spam.

    Thanks

    Does your maildomain have a valid DNS record that can be reversed in DNS? Is there any error in the logs that provides more detail?
