The 60E device is configured to use an internal SMTP server. The server has IP address 192.168.220.2 is running Postfix on Linux. The Fortigate is 192.168.220.1. Here is the output of "config system email-server":

config system email-server
    set reply-to "user@domain.com"
    set server "192.168.220.2"
end

Here is the output of "config system alertemail settings":

config alertemail setting
    set username "user@domain.com"
    set mailto1 "user@domain.com"
    set antivirus-logs enable
    set FDS-license-expiring-warning enable
    set FDS-license-expiring-days 30
end

The Postfix mail server is reporting the following in its logs when the Fortigate tries to send an email:

Jun 03 21:35:08 MX-VM postfix/smtpd[18619]: connect from _gateway[192.168.220.1]
Jun 03 21:35:08 MX-VM postfix/smtpd[18619]: warning: Illegal address syntax from _gateway[192.168.220.1] in MAIL command: <noreply@192.168.220.2>
Jun 03 21:35:08 MX-VM postfix/smtpd[18619]: disconnect from _gateway[192.168.220.1] ehlo=1 mail=0/1 quit=1 commands=2/3

Seems like the Fortigate is trying to use "noreply@192.168.220.2" as the From: value.

Whats going on?

Hey there,

try this: unset reply-to under 'config system email-server'

or set 'source -ip' under 'config system email-server' (to the ip of the "email sending" interface)

Here is the config with the requested changes:

MYFORTINET # show system automation-action 
config system automation-action
    edit "alert-conf-change_email"
        set action-type email
        set email-to "MYEMAILADDRESS"
        set email-from "MYEMAILADDRESS"
        set email-subject "Fortigate Config Changed"

        set message "test"
    next
end

MYFORTINET # show system automation-destination
config system automation-destination
    edit "0"
        set destination "SERIALNUMBER"
    next
end

MYFORTINET # show system automation-stitch
config system automation-stitch
    edit "alert-conf-change"
        set trigger "alert-conf-change"
        set action "alert-conf-change_email"
    next
end

MYFORTINET # show system automation-trigger
config system automation-trigger
    edit "alert-conf-change"
        set event-type config-change
    next
end

MYFORTINET # show system email-server
config system email-server
    set server "MAIL_SERVER_IP"
    set source-ip FORTINET_IP
end

Here is the output of the requested commands. The test email from these commands arrives successfully, but the emails notifying a config change fail with the "illegal syntax" error:

I have tried deleting all the "config automation" entries and re-adding them with the CLI instead of the GUI, but this changed nothing.
