[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
by Thomas Leuxner 05 Jan '13

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.

[Dovecot] Non-standard fields?
by Attila Nagy 04 Jan '13

04 Jan '13

Hi, Non-standard fields are mentioned here: http://wiki2.dovecot.org/MailboxFormat/Maildir and they are stated as currently not used. Questions: - am I right that if they will be used, they will be key=value pairs, like fields in the base filename? Like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,X=12,A=something - or are they supposed to be flags, like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,ABCD - are there any plans to utilize these? Thanks,

[Dovecot] Dovecot Virtual Users with Sendmail
by DormitionSkete＠hotmail.com 04 Jan '13

04 Jan '13

I'm trying to get Dovecot working with Virtual Users and Sendmail on OpenIndiana 151a7. OpenIndiana is the Open Source continuation of OpenSolaris after Oracle tried to kill it off a couple of years ago shortly after acquiring Sun Microsystems. I'm not sure if this is so much a Dovecot problem, as much of a Sendmail problem. I thought this would probably be a better list to start with, though. If not, please let me know. I initially used this Dovecot wiki page to approach this: Simple Virtual User Installation http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall I had to make few minor changes, but I don't think anything significant to the problem I'm having. I can log into SquirrelMail with both virtual users, and with system users. I can send mail to system users from both virtual and system users. I can see the mail that I sent in the Sent Messages folder for both types of users. I just can't send mail to virtual users. When I try to, I get the following message: ERROR: Message not sent. Server replied: Requested action not taken: mailbox unavailable 550 5.1.1 <dswebstore@localhost>... User unknown My configuration info is as follows: systemuser@openindiana:~# /usr/local/sbin/dovecot --version 2.1.12 systemuser@openindiana:~# /usr/local/sbin/dovecot -n # 2.1.12: /usr/local/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 101 info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = mbox:/home/vmail/%u/mail:INBOX=/var/mail/%u passdb { args = /usr/local/etc/dovecot/passwd driver = passwd-file } pop3_uidl_format = %g protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } } ssl = no userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { postmaster_address = systemuser@localhost } --- My dovecot password file looks something like this, though changed for obvious security reasons: systemuser:{PLAIN} systemuserPASS virtualuser1:{PLAIN}virtualuser1PASS virtualuser2:{PLAIN}virtualuser2PASS --- I read on this page that I needed to put the following in my sendmail dovecot.m4 file: Dovecot LDA with Sendmail http://wiki2.dovecot.org/LDA/Sendmail So this is my dovecot.m4 file, which shows up in my sendmail.cf file after recompiling my sendmail.mc file. ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=DFMPhnu9, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u --- Finally, this is my sendmail.mc file: divert(-1) # # Copyright (c) 1983 Eric P.
