#5 Valid characters for the local-part of the address

[moxlotus]

We only consider thes charcters to be valid:
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_-.0123456789"
But saw here [http://en.wikipedia.org/wiki/E-mail_address], that those carcaters wher good too :
! # $ % & ' * + / = ? ^ ` { | } ~

From same reference [http://en.wikipedia.org/wiki/E-mail_address]:
Notwithstanding the addresses permitted by these standards, some systems impose more restrictions on email addresses, both in email addresses created on the system and in email addresses to which messages can be sent. Hotmail, for example, only allows creation of email addresses using alphanumerics and . _ - and will not allow sending mail to any email address containing ! # $ % * + / ? | ^ { } ` ~

--> E-mails to addresses containing characters not handled by user's SMTP server will fail to be delivered. This is not acceptable. I recommend setting the list of acceptable characters in the BulkMailer configuration file.
