Question about namespaces
by J Doe 21 Aug '23

21 Aug '23

Hello, I have a question regarding namespaces. My current dovecot.conf is rather basic when it comes to namespaces - I have one private namespace per user: namespace inbox { type = private separator = / inbox = yes hidden = no list = yes subscriptions = yes } I have some users who connect via more than one client - for instance, some use Apple Mail in addition to Roundcube. I have noticed that different mail clients sometimes create similar mailboxes, such as Trash and Deleted Items. I would like the same mailboxes across any client, so I am wondering if there is a way in Dovecot to specify the folders and have the *client* not create them. For instance, a config in dovecot.conf that specifies a Trash folder and the mail clients cannot create "Deleted Items", etc. in addition to this. Is this possible ? Thanks, - J

Backing up m(d)box - rsync?
by donotspam＠fastmail.fm 19 Aug '23

Hello, I manage a small number of email accounts for a voluntary organisation on a shared hosting platform. $ dovecot --version 2.3.13 (89f716dc2) I would like to keep automated local backups, but do not have access to doveadm. I have seen a couple of forum posts where users have have suggested that using rsync to backup m(d)box folders can corrupt dovecot's indexes, but there is no further explanation, and this is apparently not a problem for maildir. Our host seems to use mdbox. Does doveadm provide some sort of transaction/locking mechanism to prevent consistency problems? Others seem to recommend using tar but I don't see what difference that should make. Given that cpanel backups (provided as tar.gz archives of the home directory) include mail/ and seem to be copies of the filesystem at a particular time (though not true "snapshots" as such), aren't these just as "safe" as an rsync-ed backup? Can anyone confirm/deny/shed any light on the issue(s), if indeed any? Many thanks, Gareth

last_login using fs:posix does not autocreate the last-login directory
by karl＠denninger.net 13 Aug '23

13 Aug '23

I am using the last_login plug-in on a relatively small system to populate the last access time for users in the directory format. I don't want to have this go into an SQL database or similar as the userbase is small and shell access to the information for other purposes is useful. I have this in the conf.d directory under the configuration dir in 20-lastlogin.conf: protocol imap { mail_plugins = $mail_plugins last_login } plugin { last_login_dict = fs:posix:prefix=/var/run/dovecot/ } This works except that while the prefix is there the "last-login" directory under the prefix gets removed on restart (as you think it might) and I can't find an example of how to have it auto-created. This results in a bunch of logged errors until I re-create that working directory under the base. Am I missing something obvious?

sso / sharing authenticated sessions how does it work
by Marc 12 Aug '23

12 Aug '23

I am totally not experienced with setting up sso etc. I was wondering if/how it is possible to share an authenticated session between dovecot and the mail client with the webmail so a user does not need to login again.

Dovecot and Thunderbird 15
by Elise 10 Aug '23

10 Aug '23

Hi, I recently had some issues with Thunderbird 15 when removing e-mail. With my other mailclient Outlook I could without any issue. As I don't grand POP3 mail pickup, I disabled that in dovecot.conf #service pop3-login { # inet_listener pop3 { # address = 10.10.10.52 # } # inet_listener pop3s { # address = 10.10.10.52 # } #} Enabling the above and restarting Dovecot solved the issue. Is it TB related or do I overlook a config parameter? E.

Question about custom flags
by d.meister-braeuer＠heinlein-support.de 09 Aug '23

09 Aug '23

Hello all, RFC3501 describes among other things that custom flags can be set for mails. These can be allowed or forbidden in the server: "Servers MAY permit the client to define new keywords in the mailbox". When I am on our server, it also looks like dovecot basically allows this: a select INBOX FLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded Old $ITipAnalyzed $ITipProcessed Forwarded NonJunk $cl_1 $cl_2 $cl_3) OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded Old $ITipAnalyzed $ITipProcessed Forwarded NonJunk $cl_1 $cl_2 $cl_3 \*)] Flags permitted. The only option that goes in this direction is this one: mail_max_keyword_length But basically describes something else as well, if I see it correctly. Is there a way to prevent dovecot from giving custom flags, or what is the name of the parameter where you can set this? Best

Outlook not showing all email in inbox at random
by David Koski 08 Aug '23

08 Aug '23

I manage IT for a small office with about 10 workstations. Dovecot has been installed for years and is now at 2.3.4.1-5 (Debian). I just discovered that the user cannot see many emails in the inbox. I was alerted when email was not appearing to be coming in for many hours. Other users observed the same thing. On investigation, I noticed many inbox emails missing in the Outlook GUI from times past that were on the server. It appears to be a broken client (Outlook 2019) to me but troubleshooting has yielded no solid leads. The profile and OST files have been re-created many times with no change in outcome. Each time, the inbox does not synchronize about 40 most recent emails but does for the last one for the day before and many before that. It may well be an Outlook issue so I'm looking for information to work around an Outlook bug if necessary. Thunderbird works perfectly. Also, interestingly, I can copy email from Thunderbird (or move emails on the server) to a temporary directory form the inbox, then move them back and they will appear if I don't move too many at a time.

Application to automate mail-crypt plugin with user keys
by Benedikt Zumtobel 08 Aug '23

08 Aug '23

Hi everyone, I run a very small (about 10 users) mailserver setup with the mail-crypt plugin activated and wanted to transition from a global key setup to user keys. Since I couldn't find a satisfying solution to reencrypt mailboxes when users change their password I started writing a script that ended up being a small webservice giving users a simple selfservice portal to change their password. I consider it pretty much done by now and it's public on github. Maybe it's useful for somebody else. However its use case is very narrow since I initially wrote this just for myself. It does only support a Postgres user store for instance. The main reason, however, for this post is me wondering if anybody would bother to give me some feedback. Especially for the following aspects: I execute doveadm from within my application. The advantage is that I can keep the code very light (~650 lines of code) while at the same time don't have to care about the crypto stuff which I wouldn't dare trying anyways. The disadvantage of this approach is that I had to write a doveadm wrapper that needs the setuid bit to execute doveadm mailbox commands. I consider this a bit hacky but a better solution didn't come to my mind. Another aspect is the password that is being used to encrypt the private key. When creating a new user in the database I generate a unique salt. This salt is prefixed to the user's clear text password and the resulting string is run trough the sha3-512 hash function. The output is the mail_crypt_private_password. You find the project here: https://github.com/nonce9/pwch Criticism is welcome. Benedikt
