I have just implemented the open source version 7 of zimbra and its honestly a wonderful product.
had initial trouble but got everything working fine.
we would be moving to the NE version but just in initial stages and letting all our users to get comfortable with
The issue i am having is not really directly related to zimbra but i would hightly apprecite n be thnkful if someone out there would advice and help me
I am running the followin for a couple of years with absolutlety no issues
with Sendmail as mta, mail Scanner, mailwatch,and squirrel mail
the same server runs Bind as my primary dns server and ofcourse on a public IP
domain name is --- example.com
Now i have implemented zimbra OPen source version on a private IP ( 172.16.10.1 ) a
sub domain name --- mail.example.com
created a couple of users and everything working perfect. users are able to send mail to one user to another and also to users on example.com and also they can reply back
I needed the zimbra mail users to send emails to outside world so i used my current sendmail server as a relay in mta setting in admin console and as a zimbra user able to send mail to yahoo perfectly
I changed the MX record from the private ip of zimbra host to the ip of my current sendmail cum dns server setup a split dns and checked.
when i send a mail from yahoo to a zimbra user ( i monitor my mail log on the sendmail server ) the mail comes but it is returned back saying no such user..
the error is obvious since there is no user present on the sendmail server.
the user is actually on the zimbra server
Now how would i get mail from outside world get to my zimbra server or basically how could i forward mail comming to email@example.com to my zimbra server
i dont want the zimbra server to have a public IP .. tried googling a lot but no much luck
would really apprecite your advice and help
