Ruby

A library for setting up Ruby objects as test data.

Mail::Message#reply_to

Returns the Reply-To value of the mail object as an array of strings of
address specs.

Example:

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

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

Example:

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

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

Example:

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