Hello

When I try to send email with the system function "SendEmail" in WinCC Unified PC V21 I get always the Error:

session: 0009, trace: SystemFunction 'SendEmail' failed! error=ResultCode: 0x80409014 Error: Description: (File: D:\agent\_work\16\s\source\ScriptCommunicationObjectModel\HmiCommunicationSysFct.cpp, Func: CCScriptFW::CHmiCommunicationSysFct::SendEmail)

I have done follwing configuration:

1) Server address  "smtp.mymailserver.XXX.com"

2) Port  25 or 587 (both tried)

3) Sender "mysystemuser@XXX.com"  (with the related password)

4) From my RT server I tried <telnet "smtp.mymailserver.XXX.com 25> , and I got responce, that means firewall rules are OK.

5) I have added the root certificate of the mail server to RT server and also to Runtime Manager

With the same settings we can send mails from other applications without problem. But for WinCC unified, for all setting combinations I always get the same error. I think there is something basic missing point.
