Question

I am using this sample code:

http://www.jondev.net/articles/Sending_Emails_without_User_Intervention_%28no_Intents%29_in_Android

I am trying to use my own server email to send email without intent on Android.

I know that sample is configured to works only with Gmail.

I have changed:

    _host = "smtp.myserver.com"; // default smtp server 
    _port = "587"; // default smtp port 
    _sport = "587"; // default socketfactory port 

and this on MainActivity:

Mail m = new Mail("[e-mail]", "password"); //to my sever email

I just set the right information on Outlook, and it works, I could send and receive from this email.

Server allow this setup:

POP3
SMTP
IMAP
WebMail
Mobile/PDA

Question:

I need to add/change something more? Or this sample can´t work with other then gmail.

I got this error on Logcat:

Answer 1

I’ve never used this wrapper, but the code is assuming SSL support while it appears your port 587 server does not support SSL. Comment out these 2 lines

props.put("mail.smtp.socketFactory.port", _sport); 
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 

and set this line from false to true

props.put("mail.smtp.socketFactory.fallback", "false"); 

That might help out.
