       Net::SMTP::TLS - An SMTP client supporting TLS and AUTH


       Version 0.12


        use Net::SMTP::TLS;
        my $mailer = new Net::SMTP::TLS(
               Hello   =>      '',
               Port    =>      25, #redundant
               User    =>      'emailguy',
               Password=>      's3cr3t');
        $mailer->datasend("Sent thru TLS!");


       Net::SMTP::TLS is a TLS and AUTH capable SMTP client which offers an interface that users
       will find familiar from Net::SMTP. Net::SMTP::TLS implements a subset of the methods
       provided by that module, but certainly not (yet) a complete mirror image of that API.

       The methods supported by Net::SMTP::TLS are used in the above example. Though self
       explanatory for the most part, please see the perldoc for Net::SMTP if you are unclear.

       The differences in the methods provided are as follows:

           The mail method does not take the options list taken by Net::SMTP

           The to method also does not take options, and is the only method available to set the
           recipient (unlike the many synonyms provided by Net::SMTP).

           The constructor takes a limited number of Net::SMTP's parameters. The constructor for
           Net::SMTP::TLS takes the following (in addition to the hostname of the mail server,
           which must be the first parameter and is not explicitly named):

               NoTLS - In the unlikely event that you need to use this class to perform non-TLS
               SMTP (you ought to be using Net::SMTP itself for that...), this will turn off TLS
               when supplied with a true value. This will most often cause an error related to
               authentication when used on a server that requires TLS

               Hello - hostname used in the EHLO command

               Port - port to connect to the SMTP service (defaults to 25)

               Timeout - Timeout for initial socket connection (defaults to 5, passed directly to

               User - username for SMTP AUTH

               Password - password for SMTP AUTH

TLS and AUTHentication

       During construction of an Net::SMTP::TLS instance, the full login process will occur. This
       involves first sending EHLO to the server, then initiating a TLS session through STARTTLS.
       Once this is complete, the module will attempt to login using the credentials supplied by
       the constructor, if such credentials have been supplied.

       The AUTH method will depend on the features returned by the server after the EHLO command.
       Based on that, CRAM-MD5 will be used if available, followed by LOGIN, followed by PLAIN.
       Please note that LOGIN is the only method of authentication that has been tested. CRAM-MD5
       and PLAIN login functionality was taken directly from the script mentioned in the
       acknowledgements section, however, I have not tested them personally.


       This module will croak in the event of an SMTP error. Should you wish to handle this
       gracefully in your application, you may wrap your mail transmission in an eval {} block
       and check $@ afterward.


       This code was blatantly plagiarized from Michal Ludvig's script. See
       <> for his excellent work.
