Send email via MATLAB

Question

I need to send an email via MATLAB and I've read the instructions for sendmail and lots of answers around here. I've tried 3 email providers and I can't really use any of them:

• Gmail: I can only send email when I deactivate my anivirus

• Hotmail and Yahoo: Error using sendmail (line 171) Exception reading response; Connection reset

• Hotmail and Yahoo (antivirus off): Error using sendmail (line 171) Exception reading response; Unrecognized SSL message, plaintext connection?

---

Here's the code

mail = 'user@service.com'; 
password = 'passwordgoeshere';
setpref('Internet','SMTP_Server','smtp.server.com');
setpref('Internet','E_mail',mail);
setpref('Internet','SMTP_Username',mail);
setpref('Internet','SMTP_Password',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',port);
sendmail(mail,'Test from MATLAB','Hello! This is a test from MATLAB!')

I've used the following variables:

• Gmail: smtp.gmail.com port=465

• Hotmail: smtp.live.com port=465 and port=587

• Yahoo: smtp.mail.yahoo.com port=587

Since deactivating the antivirus is not a good option, can anyone help me solving this?

Thank you

Answer 1

An alternative way on linux is to run a command line that send the email.

unix('echo "message" | mail -s "subject" example@gmail.com');

A similar method should be available for windows.

Answer 2

For Gmail

Change your settings to allow less secure apps to access your account. Go to the "Less secure apps" section in My Account. Next to "Access for less secure apps," select Turn on. (Note to Google Apps users: This setting is hidden if your administrator has locked less secure app account access.)

In Matlab:

mail = 'user@otherdomain.com';
password = 'myPassword';

% Set up the preferences
setpref('Internet','E_mail',mail);
setpref('Internet','SMTP_Server','smtp.gmail.com');
setpref('Internet','SMTP_Username',mail);
setpref('Internet','SMTP_Password',password);

% The following is necessary only if you are using GMail as
% your SMTP server. 
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');

subject = 'Test subject';
message = 'Test message';

sendmail(mail,subject,message)

Answer 3

Simply declare

mail = 'user';

Drop the extension @service.com for the variable mail.

Answer 4

You can read https://support.kaspersky.com/4175 and get some IDEA about settings of your AntiVirus software then you can try to send email.

Here, I am going to explain using Gmail with port as 587 to send email.

Note: I will update the answer once I will get solutions for Hotmail & Yahoo.

I have tried sending emails in multiple ways that I have mentioned in the PDF which publicly available at Sending email(GMAIL) using MATLAB.

In Sending email(GMAIL) using MATLAB PDF, you will see the following with an excellent example codes and pictures.

1. Sending email to a single user - (Only with Header message)
2. Sending email to multiple users - (With Header and body messages)
3. Sending email to multiple users - (With Header, body messages and 1 jpg file from system)
4. Sending email to multiple users - (With Header, body messages and 2 attachments .jpg and .pdf)

Thanks.
