# = In-Reply-To Field
#
# The In-Reply-To field inherits from StructuredField and handles the
# In-Reply-To: header field in the email.
#
# Sending in_reply_to to a mail message will instantiate a Mail::Field object that
# has a InReplyToField as its field type. This includes all Mail::CommonMessageId
# module instance metods.
#
# Note that, the #message_ids method will return an array of message IDs without the
# enclosing angle brackets which per RFC are not syntactically part of the message id.
#
# Only one InReplyTo field can appear in a header, though it can have multiple
# Message IDs.
#
# == Examples:
#
# mail = Mail.new
# mail.in_reply_to = '<F6E2D0B4-CC35-4A91-BA4C-C7C712B10C13@test.me.dom>'
# mail.in_reply_to #=> '<F6E2D0B4-CC35-4A91-BA4C-C7C712B10C13@test.me.dom>'
# mail[:in_reply_to] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::InReplyToField:0x180e1c4
# mail['in_reply_to'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::InReplyToField:0x180e1c4
# mail['In-Reply-To'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::InReplyToField:0x180e1c4
#
# mail[:in_reply_to].message_ids #=> ['F6E2D0B4-CC35-4A91-BA4C-C7C712B10C13@test.me.dom']
