Mario, follow this demo on how to send an email from a gmail account using matlab. You're close - you just have to make some small adjustment.

im still getting this error msg:

Could not connect to SMTP host:

smtp.gmail.com, port: 25;

Connection refused: connect

Error in Untitled (line 49)

sendmail(destination,subj,msg);

All you have to do is copy the demo in the link, fill in your email info at the top, and make sure your gmail security is turned off. That demo includes a link to instructions on how to turn off the gmail security. I and many others have used this method with success.

If you're still having problems, copy-paste your full code in the comments below but enter fake email data to protect your identity.

Googles security turned off....

Error message:

Error using sendmail (line 171)

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

25;

Connection refused: connect

Error in Untitled (line 49)

sendmail(destination,subj,msg);

--------------------------

% User input

source = '[e-mail]'; %from address (gmail)

destination = '[e-mail]'; %to address (any mail service)

myEmailPassword = '1234'; %the password to the 'from' account

subj = 'This is the subject line of the email'; % subject line

msg = 'This is the main body of the email.'; % main body of email.

%set up SMTP service for Gmail

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

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

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

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

% Gmail 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');

% Send the email

sendmail(destination,subj,msg);

% [Optional] Remove the preferences (for privacy reasons)

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

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

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

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

Ah, this is also a common problem. I'll update that post to mention this. Thanks for following up!
