ACL for system users?
by Rubén Fernández Asensio 13 Apr '18

13 Apr '18

Hello all, I'm setting up an IMAP server with dovecot. I've set up system users with PAM authentication and Maildir maiboxes. I'd like to share mailboxes among them, but regardless of what I try, I bump into filesystem permissions. I want to have Maildirs created for new users with the right permissions. I even changed "UMASK" in file /etc/login.defs from 022 to 002, but the Maildirs are still created with 700 permissions: ls -l /home/ximplet2/ total 4 drwx------ 9 ximplet2 users 4096 Apr 12 19:10 Maildir Really there's no better way than running "chmod -R g=u /home/ximplet2/Maildir" and "chmod g+s /home/ximplet2/Maildir" for every user? Really?? I read that, before v.2, Dovecot had a "umask" option to do precisely want I need, but it was removed. How are we supposed to use ACL with system users nowadays?

Hi, This code path is only executed when there is a return-path header. Given the fact that this fails consistently, can you provide an example of a message successfully delivered using an older version of Dovecot; i.e., as it is stored in the mailbox? There should be a return-path header there. Alternatively, you could temporarily wrap dovecot-lda in a shell script that copies the message to some file you can read after. I just need one example to confirm my suspicions. Regards, Stephan.

dovecot, imap sieve, roundcube markasjunk2 plugin
by David Mehler 10 Apr '18

10 Apr '18

Hello, Does anyone have the above combination going? Per the wiki: https://wiki.dovecot.org/HowTo/AntispamWithSieve I have configured Dovecot for imap sieve and rspamd setting up the learn sieve and shell scripts. This is working. Now i'd like to integrate roundcube's markasjunk2 plugin. Looking at it's config file I am uncertain as to which options to enable. If anyone has a working markasjunk2 roundcube config that works with dovecot and imap sieve i'd appreciate seeing it. Thanks. Dave.

IMAP_ID_LOG
by j.emerlik 09 Apr '18

09 Apr '18

Hi, there in configuration is possibile to set imap_id_log for logging Client ID e.g.: ID sent: name=Thunderbird, version=52.7.0. Is possible to set same but for POP3 or SMTP Auth ? Ideally, it would be possible to log in to the database e.g. using postlogin script. Regards, MattX

Filesystem level backups?
by Steve Atkins 09 Apr '18

09 Apr '18

Up until now I've been backing up my IMAP server by taking an atomic snapshot of the entire VM, so I've not really had to worry about it. I'm moving to hosting where I have neither VM snapshots nor a filesystem that can take snapshots, so I need to think about consistent backups a bit more. Will a simple backup of all the files of an multi-dbox give me a consistent state when I recover, or do I need to do something (e.g. lock writes to the mailbox) while I run a backup? (I could use doveadm backup if I were backing up to local storage I controlled, but I'm pushing it to offsite buckets so I'd prefer to avoid backing up the entire thing locally, then copying that offsite). Cheers, Steve
