DNS
Les problèmes de mails viennent dans 80% des cas de problèmes DNS. On peut débugguer les enregistrements DNS avec ces outils :

ou directement le Zone Check de l'Afnic

Configuration DNS
Les DNS corrects pour sendmail (Postfix est plus permissif) :
If your site is named "www.company.com" in the GUI and has the Email Server Alias "company.com", then this is the minimum set of DNS records you ought to have: company.com ---- A Record ----> <IP-Address> www.company.com ---- A Record ----> <IP-Address> company.com ---- MX Record ---> www.company.com (*) www.company.com ---- MX Record ---> www.company.com (*) <IP-Address> ---- Reverse ----> company.com or servername.company.com (**)
(*) = This MUST be the exact name (including the hostname part) of the
domain as shown in the GUI interface.
(**) You must have reverse delegation authority for that network
address in order for this to work. Or ask your network provider to set
up a reverse for you. Or at the worst check that your IP has a reverse
record already.
Configuration sendmail
Debug sendmail
Voir la config hostname de sendmail
echo '$=m' | sendmail -bt -d0.4
"mailq -d" affiche aussi ces infos, + d'autres, + la file d'attente !
trace virtusertable :
sendmail -d60.5 -bv user@domain.net
Sendmail voit-il les entrées virtusertable ?
echo '/map virtuser user@domain.net' | sendmail -bt
Sendmail en mode test
sendmail -bt > 3,0 user@domain.net ... Ctrl-D
Tester une adresse
sendmail -bv user@domain.net
Essayer aussi de recompiler les tables :
makemap hash /etc/mail/mailertable < /etc/mail/mailertable makemap hash /etc/mail/access.db < /etc/mail/access makemap hash /etc/mail/virtusertable.db < /etc/mail/virtusertable
ou
cd /etc/mail make clean make /etc/init.d/sendmail restart
ERREURS
- MX loops back to me
peut signifier un tas de chose... Dans l'ordre :
- vérifier que l'adresse IP pointe vers le FQDN et non vers localhost dans /etc/hosts
- vérifier la configuration des DNS (voir ci-dessus), notamment que le MX pointe soit vers une IP directe, soit un alias qui pointe lui-même directement versun une IP
- vérifier les adresses reverse DNS. Elle doivent pointer vers un nom de domaine.
