I get the following error when using sendmail.m (R2010b):
IOException while sending message:
Connection reset by peer: socket wrtie error
This does not happen all the times, but very frequently when I try to send consecutive emails through an automated script.
Example code:
% send 3 email with attachments
for email_counter=1:3
recipient = 'example@gmail.com';
message = [' ' 10 'Docs attached'];
subject = 'docs';
sender = 'example@gmail.com';
psswd = 'password';
attachments = {'doc1.pdf', 'doc2'};
setpref('Internet','E_mail',sender);
setpref('Internet','SMTP_Server','smtp.gmail.com');
setpref('Internet','SMTP_Username',sender);
setpref('Internet','SMTP_Password',psswd);
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');
sendmail(recipient, subject, message, attachments);
end
Typically, by email number 2 the script would crash and throw an exception.
Any help?

Hello,
Since you are observing the above error only when you call the ‘sendmail’ function in a loop, try the following steps:
1) Disable anti-virus.
2) Include a pause of 5s after the ‘sendmail’ call in each iteration of the loop to ensure that one call is completed before the next one is invoked in the following manner:
pause(5)

Hi Varun, thanks for your reply.
The problem occurs also, sometimes, for single instances of sendmail.
I had tried to use the pause command before without luck.
Instead, disabling the anti-virus seems to reduce the problem. I wonder why?
