 mail.resent_from #=> ['[email protected]']
 mail.resent_from = 'Mikel <[email protected]>, [email protected]'
 mail.resent_from #=> ['[email protected]', '[email protected]']

Also allows you to set the value by passing a value as a parameter

Example:

 mail.resent_from ['Mikel <[email protected]>']
 mail.resent_from #=> '[email protected]'

Additionally, you can append new addresses to the returned Array like
object.
