sending mail from gmail using sendmail()

Hi,

This code below used to work for me in the past (~2 years ago), but now it doesn't. Any ideas why?

Has something changed in Google's settings? Or in MATLAB?

I can tell you that my less secure apps are enabled on gmail - so that's not the problem.

Thanks, Iddo

% parameters
mail = '[e-mail]'; % my gmail address
password = 'myPassword';  % my gmail password 
host = 'smtp.gmail.com';
sendto = '[e-mail]';
Subject = 'test subject';
Message = 'test message';

% preferences
setpref('Internet','SMTP_Server', host);
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','465');

% execute
sendmail(sendto,Subject,Message)

Does it give any error message?

Check for interference with your antivirus program(s) and firewalls. These are common problems (see comments in that link).

Sorry for not posting the error message initially. Here it is:

Error using sendmail (line 175)

Could not connect to SMTP host: smtp.gmail.com, port: 25;

Connection refused: connect

Adam - thanks a lot! It was indeed the anti-virus :))

After pausing it (https://www.getavast.net/how-to/disable-turn-off), it worked.

Thanks

This appears to be a java based error. I can only suggest to go through the trouble shooting steps discussed in the comment section of the link I provided in my answer (open the link, read through the comments under the answer).

Common problems are

• Not setting up gmail correctly
• firewall
• antivirus programs
