    Default Issues getting Zimbra to receive email

    Hello all,
    I recently install Zimbra on my Ubuntu 7.04 box at home. I have a high-speed connection to the house, with a linksys wrt54g (w/dd-wrt) in between the ubuntu box and the internet. My domain name is Zimbra, and I've created MX record and an A record referring to mail.maximumhobopower.com on godaddy's DNS page. I've forwarded port 25 from the outside to my Ubuntu box, and configured my hosts file like so:
    127.0.0.1 localhost.localdomain localhost
    192.168.1.106 mail.maximumhobopower.com mail

    # The following lines are desirable for IPv6 capable hosts
    #::1 ip6-localhost ip6-loopback
    #fe00::0 ip6-localnet
    #ff00::0 ip6-mcastprefix
    #ff02::1 ip6-allnodes
    #ff02::2 ip6-allrouters
    #ff02::3 ip6-allhosts
    In my very limited experience with DNS and from what I've read on the Zimbra forums, this works for most people. It almost works for me, I can send emails all day long, but receive none. Here is the message that appears every time I send myself an email from another account:

    Aug 2 13:34:23 mail postfix/lmtp[29792]: 687D2914D06: to=, relay=none, delay=1868, status=deferred (connect to mail.maximumh
    obopower.com[69.62.216.28]: Connection refused)


    I'm out of ideas, this is my third time installing and day 2 of all-day nerding on this but I can't figure it out. Does anyone have any ideas for me? Thanks in advance,

    Stuff

    BTW, great job zimbra, you even made alt+s the shortcut for send!

    My provider is Surewest Broadband, and from work I can telnet to my computer via port 25 and issue helo commands. I thought it might be that too, but luckily that's not the case.

    dom@dom-desktop:~/incoming$ telnet mail.maximumhobopower.com 25
    Trying 69.62.216.28...
    Connected to mail.maximumhobopower.com.
    Escape character is '^]'.
    220 mail.maximumhobopower.com ESMTP Postfix
    ^]quit

    looks fine to me, does /var/log/zimbra.log show any connections?

    your mx records are a bit funny:
    maximumhobopower.com. 3600 IN MX 0 mail.maximumhobopower.com.
    maximumhobopower.com. 3600 IN MX 10 maximumhobopower.com.

    really you should just have a single record, priority 10:
    maximumhobopower.com. 3600 IN MX 10 mail.maximumhobopower.com.

    but both A records are set correctly so should work.

    Okay, I deleted the second MX and changed the priority of the first from 0 to 10. Now we wait... Thanks for the help!

    Dijichi - do you think there's any chance that my MX settings could have caused this issue?

    highly unlikely, the A records were set correctly, it's just a strange setup that's all.

    try sending an email to test@mail.maximumhobopower.com and see what shows up in /var/log/zimbra.log

    Here's what comes up when I send an email to test@mail.maximumhobopower.com:

    Aug 2 15:48:21 mail postfix/smtpd[17368]: NOQUEUE: reject: RCPT from mail.mywork.com[xx.xx.xx.xx]: 550 : Recipient address r
    ejected: mail.maximumhobopower.com; from= to= proto=ESMTP helo=
    and again, here is the log entry for when I send something to a legit account on zimbra:

    Aug 2 15:47:43 mail postfix/qmgr[19974]: 1EBD8914247: from=, size=3250, nrcpt=1 (queue active)
    Aug 2 15:47:43 mail postfix/lmtp[17153]: 1EBD8914247: to=, relay=none, delay=1486, status=deferred (connect to mail.maximumh
    obopower.com[69.62.216.28]: Connection refused)
    My work email, domain and IP were redacted.

    Thanks,

    Shawn

    where are these logs coming from, the sending server or the receiving server? you need to look at logs on your home machine, the one you want to receive on.

    These are on my home machine, running Zimbra. The text came from /var/log/zimbra.log. I just sent these from my work exchange server, so I removed the important addresses.

    oh right that explains things. mail is coming in to your server but your server can't deliver it locally as you haven't yet setup the wonder that is split-horizon dns (search on the forums). your router/isp doesn't support talking to your external ip from inside your home. zimbra (or rather postfix) is trying to talk to itself using the illegal external ip.
