hhtpsys application with SSL Apple iCloud account

I have an httpsys application, with SSL on port 443. When I try to send an email using Indy components TIdSMTP and TIdMessage, the email will not reach his destiny, e.g., I will not receive that mail and no error received, that is as it was sent successfully.
If I run the same application but without SSL, the mail is sent and received.
Any ideas why this happens?
