SMTP Problem via automation stitches

[hibym3]

Hey, I have a problem with sending mails via automation stitches. 

As example:

I want to have a mail alert, if a admin logins into the admin gui. 

I have two options to configure that:

[ol]

under Log & Report -> Email Alert Settings (which works fine) and

under Security Fabric -> Automation (which doesnt work)[/ol]

Because I maybe want to do more with the automation stitches, I want to send mails via automation stitches. 

If I use the built in smtp server from fortinet, I can send mails via my automation stitch. (but for known reasons, I dont want to use the smtp server from fortinet.)

In the event log I get the following error: Failed to send alert email from my.smtp-relay.com to my@mail.com

But I see nothing in the log from smtp server. 

my setup: 

fortigate 300e

fortiOS 6.2.3

It seems like a bug, because I know, that my smtp settings are working. 

Do you have any ideas, what could be the problem or where I get more information?

You may have to specify the "from address" via the CLI

config system automation-action

edit "Default Email"

set email-from "mail@domain.com"
