Destructively set the to field of the "Bcc:" header to equal the passed in string.

TMail will parse your contents and turn each valid email address into a TMail::Address object before assigning it to the mail message.

Example:

mail = TMail::Mail.new
mail.bcc = "Mikel <mikel@me.org>, another Mikel <mikel@you.org>"
mail.bcc_addrs #=>  [#<TMail::Address mikel@me.org>, #<TMail::Address mikel@you.org>]
