Ich habe ein Problem bei der Authentifizierung von Benutzern, die Postfix/Dovecot mit MySQL unter Ubuntu LTS verwenden. Outlook hat eine Verbindung zum Server hergestellt, aber bei der Authentifizierung ist ein Fehler aufgetreten.
unten sind die Posfix-Konfigurationseinstellungen:
append_dot_mydomain = no
biff = no
broken_sasl_auth_clients = yes
config_directory = /etc/postfix

mynetworks_style = host

und dann wird die Dovecot-Konfiguration wie folgt angezeigt:

Ich muss dafür sorgen, dass eingehende/ausgehende E-Mails funktionieren.
Antwort1
Ich glaube, Sie haben jetzt ein Problem mit der MySQL-Verbindung (wo Sie, soweit ich sehe, die Benutzerdatenbank aufbewahren). Sie sollten die Berechtigungen in MySQL überprüfen, damit Dovecot (Benutzer vmail) eine Verbindung zur richtigen Datenbank herstellen kann.
gewähren Sie „vmail“@„localhost“ alle Berechtigungen für Ihre_Datenbank.*;
(hier wird davon ausgegangen, dass die Datenbank lokal für Dovecot ist. Außerdem sind alle Berechtigungen möglicherweise etwas zu umfassend für das, was Sie wirklich benötigen. Ich denke, „Select“ würde eigentlich ausreichen?)
Antwort2
In der Schlange
smtpd_sasl_path = private/auth Basic SPAM prevention
entfernen Sie das "Basic SPAM prevention", so dass nur
smtpd_sasl_path = private/auth
Starten Sie dann Postfix neu.
Antwort3
Das Problem wird durch zwei Maßnahmen gelöst.
Entfernter Wert von:
relayhost = [smtp.buyorsell.it]:587
als
relayhost =
