How do I use SENDMAIL to send email from a SMTP server that uses authorization in MATLAB 7.10 (R2010a)?

I would like to send an email using a server that requires authorization. However, this server does not support SSL. How can I do this?

To send an email from a non-SSL SMTP server that requires authorization, please use the code below.

Make sure to substitute your actual email address, password, and SMTP server information in the first three lines of code. Contact your local technical support department to determine the address of your SMTP server.

mail = '[e-mail];    % Replace with your email address

password = 'l1ll1put';          % Replace with your email password

server = 'smtp.server.net';     % Replace with your SMTP server

props = java.lang.System.getProperties;

props.setProperty('mail.smtp.port','587');

% Apply prefs and props

setpref('Internet','E_mail',mail);

setpref('Internet','SMTP_Server',server);

setpref('Internet','SMTP_Username',mail);

setpref('Internet','SMTP_Password',password);

% Send the email

sendmail('[e-mail]', 'Test', 'Msg from MATLAB');

Note that the above commands are undocumented and may change in future MATLAB releases, but they were last verified in MATLAB 8.2 (R2013b). Also, note that SENDMAIL does not support servers that require username and password authentications in MATLAB 7.1 (R14SP3) and before, and hence the above commands will not work with those releases.
