Thanks for replying..........All services show running in zmcontrol status, I am able to telnet to port 25, no SELinux or firewall enabled, OS/WhiteBox Linux Enterprise 4, Zimbra version 4.0.1_GA_324.RHEL4. AS/AV also show running. Any other info needed will be happily supplied upon request.
As noted earlier; I am able to send email fine and access the server via my mail client. The issue is all incoming mail is not being distributed to the mailboxes but placed in the Deferred queue and it shows the server refused the connection. |
