Weblate server e-mails - problem with Google

Hi, probably there is not correct setup of Weblate server email setu. Each email I get from weblate is indicated as possible phishing:

I copy part of header of the email - I hope you will recognize, where is the problem. I think that the problem is, that you cannot send “gmai.com” emails directly from weblate server, but you have to use connection to Google mail server to get correct IP address of the sender.
