I have created a postfix server for my domain : residencebauge.fr.
I have also configured SPF to authorize only my public IP address : "v=spf1 a:vps.residencebauge.fr ip4:51.77.220.62 -all"
I have then configured DKIM and DMARC and when I check in different website, everything seems correct.
When I send an email directly from the server everything seems OK and the mail is never considered as SPAM :
echo "TEST" | mail -a "From: [email protected]" -s "TEST" [email protected]
But, my postfix server aims at relaying emails to several addresses in @residencebauge.fr. Like mailing lists in fact.
To do that, I defined my mailing list in virtual map. For example:
[email protected] [email protected]
When someone sends an email to [email protected], I would like this email is sent to [email protected] without being considered as a spam.
But it is not the case and emails are considered as spam.
When I send email from [email protected] to [email protected], the mail is received in [email protected] as a spam.
In headers I can see:
Received: from vps.residencebauge.fr (vps-3a4b84af.vps.ovh.net. [51.77.220.62])
by mx.google.com with ESMTPS id j2-20020adfe502000000b002dd02867a56si8919660wrm.263.2023.04.17.14.11.17

I guess the issue is because "google.com: 51.77.220.62 is neither permitted nor denied by domain of [email protected]" but I don't find what to do to fix it.
Does someone have any idea?
