Log4j SMTPAppender

Question

I have some problems trying to play with SMTPAppender . Here is my property file concerning the SMTPAppender:

#Email config
log4j.appender.mail=org.apache.log4j.net.SMTPAppender
#defines how often emails are send
log4j.appender.mail.BufferSize=1
log4j.appender.mail.SMTPHost=smtp.me.com
log4j.appender.mail.SMTPUsername=username
log4j.appender.mail.SMTPPassword=something
log4j.appender.mail.From=Myselft@mac.com
log4j.appender.mail.To=ABeautifulGirlWaitingForMe@SomeWhere.com
log4j.appender.mail.Subject="Application.log error occurred"
log4j.appender.mail.layout=org.apache.log4j.PatternLayout
log4j.appender.mail.layout.ConversionPattern=%d %5p [%c] %n%m%n

When I launch my program, I have this error message:

log4j:ERROR Error occured while sending e-mail notification.
javax.mail.MessagingException: Unknown SMTP host: smtp.me.com;
  nested exception is:
    java.net.UnknownHostException: smtp.me.com
    at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1389)
    at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:412)

I have to say that I'm totally new in the mail world. And as far as I'm aware smt.me.com exist, it's Apple Mobile Me service.

I wonder if there is a possibility that the problem is due to a special configuration in my work computer? Maybe they can scan and stop certain process like this one?

Answer 1

First of all, try

dig smtp.me.com

or

nslookup smtp.me.com

On the same workstation where your are running your program. If the above commands don't return a meaningful IP address then you have a DNS issues.

You will need to create an A record for smtp.me.com .
