when I run the code I get my sending email is not a valid base code

Please provide the full, copy-pasted error message and show the line that is throwing the error.

Note that virus software and firewalls are common problems as discussed here:

Error using sendmail (line 175)

Authentication failed.

Error in emailll (line 13)

sendmail(emailto, 'My Subject', 'My message');

Now I'm just not autherized. Any ideas how to fix it? It's the correct username and password.

I've also turned on access for unsecured apps.

[Adam Danz]

Here are some things to try:

• First I would triple-check that the access to unsecured apps is indeed turned off.
• Then triple check that there are no typos in your email adderess and password (case sensitive!)
• Confirm that your antivirus program isn't interfering by disabling your antivirus program temporarily and try to send the email again.
• If that didn't work, do the same process for any firewall programs you might be using.
• One forum member suggested that for some service providers the extension "@gmail.com" in the UserName variable may cause authentication error [1].
• You could try using a proxy server [2]

Please follow-up to let us know what worked and didn't work.

content = 'This function works for me on gmail - try it...'
e_mail(content)


function e_mail(Content)

recipient = {'emailWhereToSend1','emailWhereToSend2'};
Subject = 'My Subject';
UserName = '[e-mail]';    
Password = 'my password';          
Server = 'smtp.gmail.com';     

props = java.lang.System.getProperties;
props.setProperty('mail.smtp.port', '587');
props.setProperty('mail.smtp.auth','true');
props.setProperty('mail.smtp.starttls.enable','true');
setpref('Internet','E_mail', UserName);
setpref('Internet','SMTP_Server', Server);
setpref('Internet','SMTP_Username', UserName);
