No, that's your Domain Name and is incorrect as the FQDN for your server. Your hostname would be mail plus the domain name and that gives you the FQDN (Fully Qualified Domain Name) of mail.lsnet.in Check the Zimbra Documentation.

That's the cause of your poblems, the hostname can't be resolved. My suggestion would be to uninstall Zimbra then delete the /opt/zimbra directory (I'm assuming this is a test system with nothing important on it).
When you removed Zimbra, change the hostname to mail.lsnet.in and also modify your DNS records as I mentioned in the last post. Once that's done you can reinstall Zimbra, during the install you'll be asked if you want to change the Domain Name - you answer yes to that and set the Domain Name to lsnet.in. You will then have the correct domain name in your email.
You are advised to have a reverse DNS for your server as some receiving mail servers will reject your mail or tag it as possible spam.
