Sending an email in Matlab

I have figured out “sending an email in matlab” from https://www.mathworks.com/help/matlab/import_export/sending-email.html

https://www.mathworks.com/help/matlab/ref/sendmail.html

and some web searching.

 

% setting up an email address and SMTP server information with ‘setpref’ Matlab function.

 

mail = ‘xxxxx@gmail.com'; % gmail address

password = 'xxxxxxxx';  % gamail password

 

% outgoing SMTP server address

% setpref('Internet','SMTP_Server','mail.server.network');

setpref('Internet','SMTP_Server','smtp.gmail.com');

 

% setting up my email address and password

% setpref('Internet','E_mail','youraddress@yourserver.com');

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

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

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

 

% using ‘sendmail’ command

% Because ‘sendmail’ does not support HTML format messages, we can send HTML

% message using attachment option

 

% According to Matlab manual, ‘sendmail’ function does not support email servers that require

% authentication.  

% User need to change system setting and set preferences for the SMTP user name and password

props = java.lang.System.getProperties;

props.setProperty('mail.smtp.auth','true');

 

props.setProperty('mail.smtp.socketFactory.class','javax.net.ssl.SSLSocketFactory');

props.setProperty('mail.smtp.socketFactory.port','465');

% I am not sure what the above line means but maybe find some information from

% https://support.google.com/a/answer/176600?hl=en

 

% recipient email address

sendmail('xxxxxxxx@hotmail.com','Hello From MATLAB!');

 

When I ran this code, I’ve got the following error message.

Through web searching, I found a kind guy explained why there is an authentication error when using ‘sendmail’.

Need an additional setup in my gmail account to resolve the authentication error. Please see the following website for further information.

We need to turn on to allow less secure apps at the following address https://myaccount.google.com/lesssecureapps

I could check the authentication error in my gmail account. When I tried to send an email without allowing less secure apps, I’ve got the following message from google.

Finally, everything works fine after turning on the less secure apps, and I can check the email.

There are some options in Matlab such as using multiple recipients and attaching files. But I may not use Matlab often to send emails.
