Bonjour, je viens de remarquer que je ne peux plus envoyer ni recevoir de mail. J'ai testé au niveau de rainloop IMAP et SMTP sont ok. J'ai regardé dans le fichier /var/log/mail.log et j'ai ce type d'erreur:

Apr 26 16:32:23 toto postfix/smtpd[25369]: connect from ***-***-***-***.adsl.com[***.***.***.***]

C'est un problème au niveau d'opendkim ?

Ce serait un problème au niveau de opendmarc? Soit, vérifier dkim et spdf.

J'ai vérifié dkim avec l'outil cité ci-dessus http://dkimcore.org/c/keycheck, il me dit bien "This is a valid DKIM key record".
J'ai vérifié la configuration de spdf, tout semble correcte.

Cela fonctionnait avant, je ne comprend pas pourquoi d'un seul coup cela ne fonctionne plus :/

Bonjour a tous,

j'ai décider de refaire une boite mail suite a mon changement de domaine , je rencontre quelques soucis notamment quand j'essaye de m'identifier avec une boite mail créer sur postfixadmin.

j'ai le msg " L'authentification a échoué" sur rainloop malgres que tout passe en vert du coté imap et smtp .

Du coté log j'ai çela :
/etc/postfix/master.cf: line 41: using backwards-compatible default setting chroot=y

Interfaces to non-Postfix software. Be sure to examine the manual

pages of the non-Postfix software to find out what options it wants.

#

Many of the following services use the Postfix pipe(8) delivery

agent. See the pipe(8) man page for information about ${recipient}

and other message envelope options.

maildrop. See the Postfix MAILDROP_README file for details.

Also specify in main.cf: maildrop_destination_recipient_limit=1

#
maildrop unix - n n - - pipe
flags=DRhu user=vmail argv=/usr/bin/maildrop -d ${recipient}

Recent Cyrus versions can use the existing "lmtp" master.cf entry.

Specify in cyrus.conf:

lmtp cmd="lmtpd -a" listen="localhost:lmtp" proto=tcp4

#

Specify in main.cf one or more of the following:

mailbox_transport = lmtp:inet:localhost

virtual_transport = lmtp:inet:localhost

Cyrus 2.1.5 (Amos Gouaux)

Also specify in main.cf: cyrus_destination_recipient_limit=1

#cyrus unix - n n - - pipe

user=cyrus argv=/cyrus/bin/deliver -e -r ${sender} -m ${extension} ${user}

Old example of delivery via Cyrus.

#old-cyrus unix - n n - - pipe

flags=R user=cyrus argv=/cyrus/bin/deliver -e -m ${extension} ${user}

See the Postfix UUCP_README file for configuration details.

Other external delivery methods.
