testsaslauthd
Die Funktion von saslauthd
kann man übrigends wie folgt testen:
testsaslauthd -f /var/run/saslauthd/mux -u USER -p PASSWORT
testsaslauthd -f /var/spool/postfix/var/run/saslauthd/mux -u USER -p PASSWORT
saslfinger
Bei Problemen mit Postfix und SASL ist der erste Schritt immer ein Lauf von saslfinger:
saslfinger
ist ein Bash-Script welches auf einfache Weise alle Informationen zum SMTP-AUTH-Setup anzeigt.
(Download: Version 1.0)
Usage
-c | Client-Side SMTP AUTH wird untersucht. Client-Side SMTP AUTH heißt Postfix (als SMTP-Daemon) nutzt SMTP AUTH zur eigenen Authentifizierung bei anderen Mail-Servern. saslfinger geht alle im smtp_sasl_password_maps eingetragene Serverum zu prüfen, ob der SMTP-Auth funktioniert/gebraucht wird. |
-h | kleiner Hilfetext. |
-s | Server-Side SMTP AUTH wird untersucht. Server-Side SMTP AUTH heißt Postfix (als SMTP-Daemon) bietet Mail-Clients SMTP AUTH an. |
Zusammenfassung:
Immer erst einmal saslfinger -s | less
ausführen.
Eine Ausgabe sieht dann z.B. so aus:
