The WebSimpleSendEmail from Xojo works fine when I run it from Xojo.
When the same project, using the same email and server credentials is deployed to Xojo Cloud, I get no errors, but also no emails.
Is there a port that needs to be opened or something like that before the email Web Example?
Yes, you will need to open the appropriate port:

Ah, ok, Thanks for the quick reply.
