I have downloaded the source code and compiled it and installed zimbra
till then there is no problem every thing worked smoothly
all the services are also perfectly running
but when i try to open the user console it displays tomcat hompage,
but the admin console is ok,i have created users
and i opened user console using http://raghu..../zimbra then it worked well and asked for user name and password
when i send a mail i has given an error :NETWORK SERVICE FAILURE
caused by exception in javax.mail.messagingexception

and in the zimbra log file i found an error like this
