    Default Problem in sending mail from Zimbra to Internet

    Hi,

    I am using Zimbra opensource ed Release 5.0.10_GA_2638 on Ubuntu server. I have a static IP. I am able to send mails to external corporate mail ids but I could not able to send mail to GMAIL, YAHOO & HOTMAIL. I am getting the following message from them. If any body had come across this issue please help me out in resolving it.

    Regards
    Richard

    This error message from google would indicate what your problem is:


    'The IP you're using to send email is not authorized...'

    In order to prevent spam, Gmail refuses mail when the sending IP address does not match the sending domain. To send mail from your server to Gmail, we suggest using the SMTP relay provided by your ISP. Please note that we are unable to whitelist IP addresses or otherwise make exceptions at this time.
    I would guess from that response that your DNS records aren't correct.
    Regards

    Check your DNS records and see if your MX & A records match the IP address that you're actually sending mail from.

    My DNS look like this
    mail.domain.com MX mail.domain.com 0
    mail.domain.com A xx.xxx.xxx.xx

    But My Server is behind the router. The static IP is set my router. I am using the split DNS. If u have any idea about this please help me out.

    You need to post the exact details of your domain name and public IP or post a link to a test of your domain (such as pingability.com) you can find plenty of DNS test sites with a search. I can't tell anything from that information.

    Refer to the link you pointed out in your post :-

    'The IP you're using to send email is not authorized...' - Gmail Help

    Seems gmail is doing a reverse lookup for your IP. Would you mind having a PTR record ?


    > set type=PTR
    > 61.246.236.78
    Server: MBMUMXXXXD001DNS005
    Address: 124.124.5.140

    Non-authoritative answer:
    78.236.246.61.in-addr.arpa name = ABTS-TN-Static-078.236.246.61.airtelbroad
    band.in

    236.246.61.in-addr.arpa nameserver = dnsblr.mantraonline.com
    236.246.61.in-addr.arpa nameserver = dnsglobal.mantraonline.com
    236.246.61.in-addr.arpa nameserver = dnsbom.mantraonline.com
    236.246.61.in-addr.arpa nameserver = aaadel.mantraonline.com
    236.246.61.in-addr.arpa nameserver = dnsdel.mantraonline.com
    aaadel.mantraonline.com internet address = 202.56.230.6
    dnsbom.mantraonline.com internet address = 202.56.240.5
    dnsdel.mantraonline.com internet address = 202.56.230.5
    dnsglobal.mantraonline.com internet address = 202.56.230.52

    Hi,

    I am on the learning curve on DNS setup. I am using everydns for setting all my DNS. It would be very helpful if you can tell how and were I can set the PTR.

    You need to ask your ISP to set-up a reverse DNS for your IP and it needs to be in the correct format for you domain, details are here:

    Men & Mice | DNS Q&A
    Reverse DNS lookup - Wikipedia, the free encyclopedia
    PTR Record - A DNS Pointer Resource Record | ItsyourIP.com
