vCenter 6.7 Email Alerts smtp uses localhost 127.0.0.1 instead of specified server

Hallo, I'm trying to setup email alerts from vcenter 6.7.
I set up right mail server  (internal lan hmailserver with ip 192.168.8.103) no auth required (limited to vcenter ip)
If I use win tool like SMTPDiagTool, I can see that hmailserver works and it reaches to deliver test email.

but... vcenter doesn't send email alert.

I tried to simulate smtp connection with putty:

echo "subject: sendmail test" | sendmail -v mymail@mydomain

It seems it tries to connecto to itself 127.0.0.1 instead of connetting to my specified server (hmailserver 192.168.8.103)

mymail@mydomain... Connecting to [127.0.0.1] via relay...

I have also followed article: https://kb.vmware.com/s/article/49725 and edited /etc/mail/submit.cf

# "Smart" relay host (may be null)
DS 192.168.8.103

no results. Vcenter tries to send via itself and doesn't care of specified mail server

Thank you for suggestions
