Overview

Only one Message-ID field may appear in a header.

Note that parsed Message IDs do not contain their enclosing angle brackets which, per RFC, are not part of the ID.

mail = Mail.new
mail.message_id = '<[email protected]>'
mail.message_id    #=> '<[email protected]>'
mail[:message_id]  #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::MessageIdField:0x180e1c4
mail['message_id'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::MessageIdField:0x180e1c4
mail['Message-ID'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::MessageIdField:0x180e1c4

mail[:message_id].message_id   #=> '[email protected]'
mail[:message_id].message_ids  #=> ['[email protected]']
