[Dovecot] wrong authentication for local delivery

Hi all there, I have a postfix/dovecot environment running with ldap authentication. I am able to deliver e-Mails to the internet and also receive them via fetchmail. I have a pure local domain (av.loc). Just for internal purpuse. For all mails where destination is a local mailbox, as for all of the local domain, delivery does not work. Here I can show some logs of such a process: +++ Here the process starts (I have sent an e-Mail to myself).

[Dovecot] dovecot as layer between postfix and thunderbird
by martin svensson 05 Jan '13

05 Jan '13

Hello, im all new to this but feel i want to have a dedicated server to handle my mails from Gmail and Hotmail Basically, i installed SMS, superb Mini Server (based on slackware), and with that default install i got: dovecot, postfix, fetchmail and sendmail. The postfix part seems to work according to a "telnet localhost 25", now i want to procede with dovecot, as i understand it, its the middle layer between (in my case) postfix and thunderbird. What i expect in the very end is a dedicated server who regulary checks and fetches mails, and lets me have all contacts info in the (already up and running) LDAP server. When i start thunderbird, i want it to go grab those mails from my local machine I am, ofcourse all over manpages, HOWTOs, guides and google, but would certainly appriciate further help and points in the right direction My apologises for any weird beginner mistakes in this post

[Dovecot] doveadm backup issue with ACL plugin enabled

Hi, when trying to backup mailboxes I noticed some hiccups when the ACL plugin is enabled. It works fine with ACL disabled: $ doveadm -o plugin/quota= backup -u tlx(a)leuxner.net mdbox:/home/backups/tlx/mdbox However, enabled (and w/ a mailbox actually using ACLs) the following error occurs: $ doveadm -o plugin/quota= backup -u tlx(a)leuxner.net mdbox:/home/backups/tlx/mdbox dsync(tlx(a)leuxner.net): Error: Couldn't update mailbox <name> metadata: Permission denied I tried to override the ACL plugin via '-o' to no avail, but I may be using the wrong syntax there.
