What app is this about
Snappy : envoi depuis snapyy ou rouncube => rejet des messages à destination de gmail (DKIM absent).
Describe your issue
Hello,
Je viens de remarquer que mes messages envoyés depuis l’application snappy (entre autres) vers google sont rejettés :
host gmail-smtp-in.l.google.com[1aa.bb.cc.dd] said:
550-5.7.26 Your email has been blocked because the sender is
unauthenticated. 550-5.7.26 Gmail requires all senders to authenticate with
either SPF or DKIM. 550-5.7.26 550-5.7.26 Authentication results:
550-5.7.26 DKIM = did not pass 550-5.7.26 SPF [geronimo22.ynh.fr] with
ip: [212.27.42.1] = did not pass 550-5.7.26 550-5.7.26 For instructions
on setting up authentication, go to 550 5.7.26
En faisant un test avec mail-tester (6/10)=> Votre message n’est pas signé avec DKIM
Pourtant quand je consulte mon DNS, tout semble bien configuré (normalement yunohost configure le DNS) ?
; Mail
@ 3600 IN MX 10 mon.domain.fr
@ 3600 IN TXT “v=spf1 a mx -all”
mail._domainkey 3600 IN TXT “v=DKIM1; h=sha256; k=rsa; p=longue clef”
_dmarc 3600 IN TXT “v=DMARC1; p=none”
Je ne suis pas un spécialiste et je ne comprends pas ce rejet 
Merci d’avance
