How do I use SENDMAIL to send email from MATLAB 7.2 (R2006a) via the GMail server or Yahoo server?

63 ビュー (過去 30 日間)
I would like to send an email from within MATLAB via the GMail/Yahoo server. If I try to do this using a script such as the following:
Using Gmail Server:
setpref('Internet','SMTP_Server','smtp.gmail.com');
setpref('Internet','E_mail','an.example.email.address@gmail.com');
sendmail('an.example.email.address@gmail.com','Test email', 'Test');
Using Yahoo Server:
setpref('Internet','SMTP_Server','smtp.mail.gmail.com');
setpref('Internet','E_mail','an.example.email.address@yahoo.com');
sendmail('an.example.email.address@yahoo.com','Test email', 'Test');
I receive the following error: ERROR: ??? Error using ==> sendmail 530 5.7.0 Must issue a STARTTLS command first b19sm1973874ana

This change has been incorporated into the documentation in Release 2011a (R2011a). For previous releases, read below for any additional information:
To send email using SENDMAIL via the GMail/Yahoo server, you can execute the following in the MATLAB Prompt:
Gmail Server:
% Define these variables appropriately:
mail = 'sendemail.example.mathworks@gmail.com'; %Your GMail email address
password = 'testing1234'; %Your GMail password
setpref('Internet','SMTP_Server','smtp.gmail.com');
Yahoo Server:
% Define these variables appropriately:
mail = 'sendemail.example_mathworks@yahoo.com'; %Your Yahoo email address
password = 'testing1234'; %Your Yahoo password
setpref('Internet','SMTP_Server','smtp.mail.yahoo.com');
Gmail/Yahoo Servers:
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');
% Send the email. Note that the first input is the address you are sending the email to
sendmail(mail,'Test from MATLAB','Hello! This is a test from MATLAB!')
In R2013a, the following command might also resolve the issue:
props.setProperty('mail.smtp.starttls.enable','true');
Note that the above commands are undocumented and may change in future MATLAB releases. Also, note that SENDMAIL does not support servers that require username and password authentications in MATLAB 7.1 (R14SP3) and before and hence the above commands will not work with those releases.

HAI... I AM USING MATLAB R2013a
I TRIED SENDMAIL CODING BUT I GET THE ERROR....
530 5.7.0 Must issue a STARTTLS command first. 5sm29774614pfn.46 - gsmtp
I SOLVE THIS ERROR BY USING COMMAND IN COMMAND WINDOW
JUST TYPE THIS COMMANDS
props = java.lang.System.getProperties;
props.setProperty( 'mail.smtp.starttls.enable', 'true' )
then run your sendmail coding ,it was worked....
Coding
mail ='123@gmail.com'; % Your mail id
password ='hai@123'; % Yore password
host = 'smtp.mail.com';
port = '587';
setpref('Internet','E_mail',mail);
setpref('Internet','SMTP_Server',host);
sendmail({'kalai@gmail.com',... 'kalai1@gmail.com'},'Matlab',... 'hai',{'C:\New folder\license.txt',... 'C:\New folder\j.pdf'}) % Receiver mail id and also send many more receiver ... send also files like doc,pdf,image,rar files
if u use any sender mail id just open and close sender mail in your using system ....because it solve authentication error by using this .

Hi,
I'm having trouble with running this code. I tried the suggestion above:
%
% parameters
mail = 'mymail@gmail.com'; % my gmail address
password = 'mypassword'; % my gmail password
host = 'smtp.mail.com';
% 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');
% Send the email
sendmail(mail,'Test from MATLAB','Hello! This is a test from MATLAB!')
But I get this error:
%
Error using sendmail (line 171)
Authentication failed.
Any ideas what might be causing this?
Thanks
