Re: Strange mail with number in subject line and body

I'd received this kind of emails in waves.
I receive it for a couple of days and don't receive it anymore for weeks 
or moths, but isn't the first wave we receive in our company.
I support the opinion of Rusell that maybe is a mechanism to check email 
addresses.
