"DKIM or DK signature exists, but is not valid" sur second domaine

[crustyourmind]

Bonjour
j’héberge 2 noms de domaines sur mon serveur
La configuration du premier est opérationnelle et aucun soucis avec les mails

Par contre pour le second, bien qu’ayant fait la même chose au niveau de l’administration, j’ai un soucis de DKIM

J’ai bien mis ceci dans ma zone DNS chez OVH (le même que pour le 1er nom de domaine, juste le nom qui change)
Configuration retournée par yonohost

; Mail
@ 3600 IN MX 10 lesnenfantsperdus.com.
@ 3600 IN TXT “v=spf1 a mx ip4:51.254.143.37 -all”
mail._domainkey 3600 IN TXT “v=DKIM1; h=sha256; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQChIBUYY4AXTHrWglQ63EAk7KpGCfUPrkqyucG0HIhj2bPBmf4atXgjzfhLOWUtoGwCFDqPmQHXlNF/9rD06PDQmtwfahagnWmgcFe6HfTAwszvPgxrG6H9qdugcjPv9Oqt5ba2QHNIr/ae9h0QimiIQ9ljNMHKri2TniexSby26QIDAQAB”
_dmarc 3600 IN TXT “v=DMARC1; p=none”

Mais quand je fais un test, j’ai cette erreur “DKIM or DK signature exists, but is not valid”

OK autant pour moi, j’avais copier la clef de mon sous domaine (www) et non de mon domaine …
Désolé du dérangement
