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

mail = 'myUsername@gmail.com'; % my gmail address

% 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');

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

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