I'm almost positive that this is NOT a valid rfc822 compliant email address:

The spec states that the local-part is:

local-part  =  word *("." word)             ; uninterpreted
                                                          ; case-preserved

Where a word is an ATOM or QUOTED STRING. An ATOM is a string of ASCII  
characters EXCEPT ()<>@,;:\".[].  The *("." word) part indicates that  
one or more occurrences of a period FOLLOWED by a word are compliant.  
In other words, the local-part cannot end with a period.
