    Default (Solved)Zimbra will receive incoming email

    I am not sure what is causing it so I am looking for another pair of eyes.

    Zimbra is able to send mail out with out any issues it has issues receiving email I checked the bind settings they check out find the first server is itself the next to two internal dns servers that forward to Google dns.

    Below is any information you may need

    # dig hilltopchurchnet.net any

    Zimbra is running on Centos 6.3 using webmin for the dns provider as well it is running in hyper-v behind a NAT that has port forwarding set for email.

    If anyone can give it another pair of eyes I am pretty sure I missed something.

    You need to look in the log files to see if there are any connection attempts for a server you know is having problems. Does this happen for all inbound mail or is it from specific servers?

    It serves no useful purpose to have two DNS A & MX records for you server (on the LAN or external), why are you doing that?

    I looked a the mailbox.log file and it showing that it is purging email not sure why, and it is for all inbound mail.

    The two nameservers are both internal as the mail server is running on a domain and the server itself and then if it can find it internally it will look out to the internet for the information. And the dual mx records are for back up just how I do my mx records for mail.

    Is this inbound mail that you're expecting? You didn't answer the rest of my question and you're going to have to provide some information about what's in the log files.

    I didn't ask about those records and I understand why they're there.

    The dual MX & A records don't act as any sort of backup when the point to the same server and therefore superfluous, just remove the extra records.

    Those messages are nothing to do with connection attempt from another server, they are normal messages for cleaning mailboxes. You need to look in /var/log/maillog to see what's happening when a server tries to connect. You need to send an email from an external account (such as gmail) not from your client, while you're doing that you should tail the log file and see what happens - for how long have you not been receiving mail?

    I just attached the zimbra log file this has been since the server died last Friday!! Cause of the Zimbra update it took and ubuntu's update I had to rebuild the server as it corrupted itself so I am now trying to get back up and working.
