Sending email with Hana Cloud

Hello Community,

my problem is to send emails with an sap account.

I followed this tutorial with an gmail account and it works fine.

https://help.hana.ondemand.com/help/frameset.htm?e70a574cbb57101494a781920e3c9d64.html

Now i want to use as the mail destination the sap email provider.

String host = "mail.sap.corp";
Properties properties = System.getProperties();

properties.setProperty("mail.smtp.host", host);

properties.setProperty("mail.smtp.starttls.enable", "true");

properties.setProperty("mail.user", sapemail@sap.com);

properties.setProperty("mail.smtp.port", "25");

properties.setProperty("mail.transport.protocol", "smtp");

When i run the programm it says "Could not connect to SMTP host: mail.sap.corp, port: 25".

Do you have any idea?

BR,

Mike
