Oui effectivement je n’avais pas fait cette distinction.
Ben écoute pour le moment je ne sais pas, ça fonctionne correctement depuis le début avec Gmail. Gandi c’est un peu plus difficile de savoir puisque c’est des domaines perso la plupart du temps.

$ sed -En 's/[a-zA-Z0-9.]*@gmail\.com/******@gmail.com/p' /var/log/mail.log
