Mail Handler should better handle messages that are rejected due to recipent not matching catch mail list

When you specify an email address in the Catch Email Address field of an Incoming Mail Handler, and an email message's recipent(s) does not match the Catch Email Address field, the following message is logged:

2013-05-28 06:44:48,156 INFO [POP Mail for TKN] QuartzWorker-1 ServiceRunner    
Create Issue / Comment for Project TKN The message has been rejected: The messages recipient(s) does not match catch mail list.

The problem here is that the mail handler does not remember that it has already "read" this email message. Everytime the mail handler scans the email account, it will see this email message and continue to output the INFO in the log files until the email message is removed.

This can become a headache when there are many email messages like these that cannot be processed. The log files will quickly be flooded with the INFO message.

JIRA should include this kind of INFO message in the Forward Email functionality, where messages that cannot be handled will trigger an email indicating this problem.
