Tu as l’application EmailPoubelle installée ?
On dirait qu’il y a un problème avec sa configuration 
En cherchant, je tombe sur ça Update 98-postfix_emailpoubelle by ericgaspar · Pull Request #27 · YunoHost-Apps/emailpoubelle_ynh · GitHub et ça Virtual_alias_maps map lookup problem // hash:/var/virtual is unavailable // srs_forward: <root@***> not rewritten: Domain excluded by policy - #7 by yacoubaa.
L’application a l’air d’avoir un problème qui casse d’autres mécanismes. Il va falloir corriger cette application. Peut-être que tester cette branche Update 98-postfix_emailpoubelle by ericgaspar · Pull Request #27 · YunoHost-Apps/emailpoubelle_ynh · GitHub serait utile
J’ai ouvert une nouvelle tentative de correction ici : fix postfix by lapineige · Pull Request #30 · YunoHost-Apps/emailpoubelle_ynh · GitHub
