Mailserver kann einige Mails nicht zustellen.

  • Hi,


    ich habe leider einige Probleme mit meinem Postfix und der Oberfläche Froxlor. Ich betreibe den Postfix auf einem CentOS 7. Folgende Probleme:


    Ich rufe meine Verwaltungsoberfläche mit der URL froxlor.meinedomain.de auf. Ich kann für andere Domains auch Mailadressen anlegen die auch alle halbwegs funktionieren (Problem 2 weiter unten). Erstelle ich eine Mailadresse wie zum Beispiel postmaster@meinedomain.de kann ich daraus auch mails versenden, nur empfangen geht nicht.


    [root@vserver3 ~]# tail -f /var/log/maillog | grep postmaster
    Aug 27 15:27:35 vserver3 postfix/local[16572]: 23EA5D00: to=<root@mail.meinedomain.de>, orig_to=<postmaster@meinedomain.de>, relay=local, delay=0.1, delays=0.1/0/0/0, dsn=4.3.0, status=deferred (temporary failure. Command output: local: fatal: execvp /usr/lib/dovecot/deliver: Permission denied )
    Aug 27 15:32:09 vserver3 postfix/local[16844]: 6990ACF5: to=<root@meinedomain.de>, orig_to=<postmaster@meinedomain.de>, relay=local, delay=465, delays=465/0.02/0/0.01, dsn=4.3.0, status=deferred (temporary failure. Command output: local: fatal: execvp /usr/lib/dovecot/deliver: Permission denied )


    Ich finde den Fehler nicht :(


    Problem 2:


    Für meine Mailadressen anderer Domains möchte ich SSL auf Port 587 aktivieren, dafür habe ich die Configs angepasst. Der Port ist auf dem Server offen, Thunderbird nimmt für das Postfach auch den Port 587. Jedoch kommen diese trotzdem nicht bei einigen Providern wie zum Beispiel AOL an. Hier meine Configs:

  • Hi,


    das habe ich schon überprüft, Besitzer ist vmail:vmail, als Berechtigung habe ich ebenfalls zu testzwecken 777 gesetzt. Auch mit root:root und postfix:postfix wird es nicht besser.


    Das Froxlorverzeichnis /var/customers/mail gehört auch vmail:vmail


    Das Verzeichnis /usr/lib/dovecot/deliver ist allerdings leer

    Der Pfad kommt mir nicht bekannt vor.


    Bei 'Permission denied' solltest du auch mal in /var/log/audit/audit.log gucken (| grep denied | grep dovecot), falls SELinux läuft.

    CentOS 7 / nginx / php-fpm / postfix / rspamd / clamav / dovecot / nextcloud running on RS 1000 SSDx4 G8 / VPS 500 G8 / VPS 2000 G8 Plus

  • Hi,


    im Logfile kann grep weder ein denied, noch ein dovecot finden. Ich habe nach beiden nochmal einzeln gegrept.


    Der Eintrag für den Pfad befindet sich in der /etc/postfix/main.cf und wird per default von froxlor so vorgegeben.
