I have already installed Zimbra open source 5.X version. Now i need to make this server as a backup mx. So i stop zimbra and configure postfix for backup mx and start only separate postfix server. Its now working but after starting postfix, it sends mails to email@example.com at every 2-3 minutes frequently.
Can you tell me why this mail is sending and how it stops?
I try to view these mail in zimbra but cannot see so can i view these mails?
Sorry i don't understand where to put my post so i put here in administrator. Sorry if i was wrong.
Help would be really appreciated.
