I have zimbra server running perfectly for quite some time
i have recently implemented a sendmail server with antispam antivirus software and is working fine
right now I am sending mail out throgh this sendmail server
the mx record which was currently for the zimbra server i changed it to the sendmail server
now the issue i have is the zimbra server cannot receive emails.
let me explain
i have gone through the post and related wikis but i could achieve what i want.
I have tried using the mailer table but it does not help
also i have tested with the routing rule compiled in sendmail but no avail
the var/maillog log just say DSN: User unknown
if I create a user on my sendmail server and in my /etc/aliases file i add
the mail is routed to my zimbra server and works perfect
now I have about 900 users on my zimbra server
and guess it quite a pain to follow up the above for all the users individually
what I would like is any mail received for my domain... domain name say email@example.com
should be just forwarded or routed by sendmail to my zimbra server
in this case i do have to create any users on my sendmail server.
I do hope this is possible or else what would be the best way to achieve this
any link that would help
i would really appreciate your kind help and advice
thanks in advance
