Using java to validate outlook email address
Background:
There are some invalid email adress in our system. I want to find all these invalid addresses. Some of these address are outlook address and some are instant message (IM) address.
Issue:
I have meet an issue when use SMTP to validate email address.
SMTP works when validate outlook address like ab1234@outlook.com.
However, SMTP failed to validate instant message (IM) address like bob.archer@corpration.com which does exist.
Is there a method using java to validate instant message (IM) address.
Hope for your reply,
Thanks.

It means this e-mail address could not receive mail. In my company, we use outlook as work mail box. Some email address is removed and couldn't receive mail any more when its owner was left from our company.

In another word, this address doesn't exist. (Could be removed, or never created).

Apache commons provides a solid validator that can help you:

Besides checking the email format (one or more alphanumeric and/or special characters followed by @ with several more alphanumeric characters separated by at least one "."), the only way to validate anything is to actually attempt to use it, be that for email or for IM.
