Thank-you for your reply Kevin. Here is the result:
Code:
[zimbra@parshwanath ~]$ host `hostname`
parshwanath.domain.net has address 192.168.1.12
parshwanath.domain.net mail is handled by 0 parshwanath.domain.net.
[zimbra@parshwanath ~]$ zmhostname
domain.net
[zimbra@parshwanath ~]$ telnet `hostname` 389
Trying 192.168.1.12...
Connected to parshwanath.domain.net (192.168.1.12).
Escape character is '^]'.
Connection closed by foreign host.
[zimbra@parshwanath ~]$
Yes, I have iptables, but they aren't blocking these ports. I haven't made any changes to rules in many days. (I checked this again right now). Telnet to port 389 works. I haven't done any thing new except adding 4 more domains yesterday - so, in all I have 7 domains and 20 users spread over these domains.
phoenix: This problem is not 4 days old - this instance of Zimbra was installed 4 days back and it was functioning well until today afternoon... when nothing happened... and I noticed that my connection to mail server was refused. So, I decided to check and noticed, Zimbra had died.
