When I try to make a rule to have certain email moved to the Junk Basket....I am given the message:

" Unfortunately, we can't make a rule for an email address that is this long."

The email addresses are like: RAByAC4ATwB6AC0ARQBuAGQA?==?UTF-16?B?bwByAHMA?==?UTF-16?B?ZQBzAC0ARwBhAHIAYwA=?==?UTF-16?B?aQBuAGkAYQBDAGEAbQA=?==?UTF-16?B?YgA=?==?UTF-16?B?bwBnAGkAYQAtAA==?=
