D'abord :

mais
smtpauth.dbmail.com internet address = 160.92.190.2
1) Est-ce que tu utilises réellement "smtpauth.dbmail.com" comme HELO-name?
2) Si oui : pourquoi? Est-ce une obligation de dbmail.com?
Ensuite :
google.com: domain of transitioning vivien_at_lafibre.info does not designate 160.92.190.1 as permitted sender
en effet :
lafibre.info text =
"v=spf1 include:mx.ovh.com ~all"
mx.ovh.com text =
"v=spf1 ptr:mail-out.ovh.net ptr:mail.ovh.net ?all"
donc la règle SPFv1 de lafibre est
+ptr:mail-out.ovh.net
+ptr:mail.ovh.net
~all
or
smtp1.dbmail.com internet address = 160.92.190.1
160.92.190.1 n'est pas dans ovh.net
donc 160.92.190.1 ne PTR match ni mail-out.ovh.net ni mail.ovh.net
donc 160.92.190.1 match ALL
donc
ton SPF SOFTFAIL l'IP 160.92.190.1
