I send a bunch of data from jsp to my email.
There following code is pieces from jsp.

It compiled with no error.
It runs successfully sent email to my email address, BUT sometimes it cannot.

Here is the message from console :

nested exception is:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
javax.mail.SendFailedException: 554 The IP Address of the sender (60.xx.22.oo) was found in a DNS blacklist database and was therefore refused.

String subject = "This is subject ";
String message = "";
 
String to = "[e-mail]";

        try {
 
        Properties props = new Properties();
        props.put("mail.smtp.host","mail.asiam.com.my");

you might wanna try http://member.dnsstuff.com/pages/tools.php

In IP tools you have spam database lookup and you can check which databases list your server. Then you can take actions... My guess is that all you need to do is send them a mail declaring that you've fixed the spam problem (but if you didn't chances are they'll list you again).

Maybe better option would be to switch server if possible...


May the source be with you!
