PeopleSoft SMTP issue

While sending mail from workflow message, I was facing the issue. Appserver log says:


SendMailException: Detail Message:JavaMail Error: DNS error.\nStack Trace:\njavax.naming.CommunicationException: DNS error [Root exception is java.net.PortUnreachableException: ICMP Port Unreachable]; remaining name 'tbrl.in'
at com.sun.jndi.dns.DnsClient.query(Unknown Source)
at com.sun.jndi.dns.Resolver.query(Unknown Source)
at com.sun.jndi.dns.DnsContext.c_getAttributes(Unknown Source)
at com.sun.jndi.toolkit.ctx.ComponentDirContext.p_getAttributes(Unknown Source)
at com.sun.jndi.toolkit.ctx.PartialCompositeDirContext.getAttributes(Unknown Source)
at com.sun.jndi

I turned on the SMTP trace from appserver and found the error as:

com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.1 Client was not authenticated


the actual issue was with Exchange server:


You can telnet the server from you application server ans try to send the mail using command

telnet xxx.xxx.xxx.xxx 25 
EHLO <your appserver IP>   
MAIL FROM: <sender mail address>   
RCPT TO: <receipient mail address>
DATA   
Subject: Test message   


Test message body   
.   
quit

if it gives the error it means the issue is with exchange server and ask you mail admin to provide required access.
