After upgraded to AE12.1.1, the send_mail function and the mail notifications are not working anymore. In previous version with the same settings: SMTP settings in the CLIENT_SETTINGS, works fine.
With an mail notification object, we get the following error:
22.02.2018 10:30:52 U00050030 The SMTP client cannot create socket, error code '9', error description: 'Bad address format'.
With the send_mail function, we get:
2018-02-22 10:30:59 - U00020408 Mail error code 50030
According to the documentation, this error code means ""50030" - Error in socket creation."
Why does the internal smtp client has to open an socket for sending a mail?
