Numerous backlogged bug fixes have been applied as well as +# Ruby 1.9 compatibility and a swath of documentation to boot. +# +# TMail allows you to treat an email totally as an object and allow you to get on with your +# own programming without having to worry about crafting the perfect email address validation +# parser, or assembling an email from all it's component parts. +# +# TMail handles the most complex part of the email - the header. It generates and parses +# headers and provides you with instant access to their innards through simple and logically +# named accessor and setter methods. +# +# TMail also provides a wrapper to Net/SMTP as well as Unix Mailbox handling methods to +# directly read emails from your unix mailbox, parse them and use them. +# +# Following is the comprehensive list of methods to access TMail::Mail objects. You can also +# check out TMail::Mail, TMail::Address and TMail::Headers for other lists. +module TMail + + # Provides an exception to throw on errors in Syntax within TMail's parsers + class SyntaxError < StandardError; end + + # Provides a new email boundary to separate parts of the email.
