doveadm quota error output in some cases
by Kai Schaetzl 05 Oct '18

05 Oct '18

I am testing a special setup on one machine where I want to put some local users that get mail locally to /home user directories via postfix transport map local: for historical and practical reasons. Other users are setup as virtual users. The local users are *also* setup as virtual users for dovecot so that I can retrieve the mail via dovecot. I changed the SQL for dovecot user_query, so that it gets the local uid and gid (and doesn't use vmail) and also gets the home directory in /home for only those users. After a bit of experimenting this works fine and I can retrieve mail via dovecot. However, there are two problems with quota and one of them has "doveadm get quota" spew out a lot of garbage that I think should actually go to a log and not to the program output. When I run a doveadm quota get -A or -u user I get four errors of this kind (for user/domain storage and message limit) for each special user: doveadm(user): Error: Failed to get quota resource STORAGE: quota-dict: dict_lookup(priv/quota/storage) failed: net_connect_unix (/var/run/dovecot/dict) failed: Permission denied (euid=500(user) egid=200(vmail) missing +r perm: /var/run/dovecot/dict, dir owned by 0:0 mode=0755) (reply took 0.000 secs (0.000 in dict wait, 0.000 in other ioloops, 0.000 in locks)) Then the normal program output follows, with error lines for these special users, of course: user STORAGE error error error The reason is that /var/run/dovecot/dict is owned by vmail:vmail (not root:root as the 0:0 suggests). I don't see a way to change this without blocking the "real" virtual users that use vmail:vmail. Shouldn't this massive error output rather go to a log? (dovecot/error.log) Or: is there a way to avoid this? /var/run/dovecot/dict is a socket. I didn't want to fiddle with it. Can I change the permissions so that it can also be accessed by other system users? Probably only to make it world-readable? If so, what are the implications of doing that? Thanks, Kai

Username aliases
by Eirik Rye 05 Oct '18

05 Oct '18

Hi, Our organization is currently using a passwd-file user database for our Dovecot installs. However, we now want to provide simple username aliases. We currently use usernames that are -not- equal to the email address, but due to the fact that many major email clients/providers do not even allow you to specifiy a username, we now want to provide aliases where the username is equal to the email address. A simple solution would be to duplicate the lines in the passwd-file, with the email address as the username, but this does not seem be ideal due to data duplication. Ideally, there would be a secondary 'alias' userdb, which on a match would then restart the search in the primary passwd-file userdb using the new username. Is this possible? What would be the best way to go about this?

vpopmail
by Eric Broch 04 Oct '18

04 Oct '18

Hello list, I run Dovecot with the vpopmail driver and have found that it authenticates against the clear text password in the vpopmail database. Is there a configuration option either at compile time, link time, or a setting in one of the configuration files that tells the program to authenticate against the hash instead of the clear text? -- Eric Broch White Horse Technical Consulting (WHTC)

Re: [ceph-users] dovecot + cephfs - sdbox vs mdbox

Thanks Jack. That's good to know. It is definitely something to consider.

Authenticate users using their firstname
by Fady AL HAYALI 04 Oct '18

04 Oct '18

Hi, I'm setting up a Postfic and Dovecot with LDAP email server. My users in LDAP is like this: dn: uid=firstname,ou=People,dc=domain,dc=com uid: firstname uidNumber: 4025 gidNumber: 4025 givenName: firstname objectClass: top objectClass: person objectClass: posixAccount objectClass: shadowAccount objectClass: organizationalPerson objectClass: inetOrgPerson loginShell: /bin/bash homeDirectory: /home/firstname cn: firstname lastname mail: firstname.lastname(a)domain.com<mailto:firstname.lastname@domain.com> This is how I connect Dovecot with LDAP hosts = ldapserver ldap_version = 3 base = ou=People,dc=domain,dc=com deref = never scope = subtree user_attrs = user_filter = (&(objectclass=inetOrgPerson)(uid=%n) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectclass=inetOrgPerson)(uid=%n)) default_pass_scheme = SSHA When I enter a user's email address and password as the following: email: firstname.lastname(a)domain.com<mailto:firstname.lastname@domain.com> password: password and according to my setting which I used "%n" as you see above, the username used to authenticate is "firstname.lastname". I checked the Dovecot variables but I couldn't find something useful in this case to manipulate the "%n" variable. I would like to keep using email addresses as "firstname.lastname(a)domain.com"<mailto:firstname.lastname@domain.com> but authenticate users using their first name. I really hit a wall here and any help will be much appreciated.

Possible architecture ?
by Alexandre Ellert 03 Oct '18

03 Oct '18

Hi, I'd like to achieve the following setup whit dovecot using multiple servers : - one server dedicated to all client IMAP (TLS) connections (i <http://mail.numeezy.com>map.mymaindomain.com, see below ) - each backend server has it's own local storage. no replication - each backend server responsible of a few domains - each backend server has it's own Mysql local database for user's passwords. ===> Server 1 : domains A, B and C ====> i <http://mail.numeezy.com>map.mymaindomain.com ===> Server 2 : domains D, E and F (143 TLS / 993 SSL) ===> Server 3 : domains G, H For example, if a user connects from domain E to i <http://mail.numeezy.com> map.mymaindomain.com, will Dovecot be able to use password database hosted on Server 2 ? Thank you ! Alex

Delete vs. Expunge in Public Namespace

All, my IMAP client [1] marks messages as deleted, but doesn't expunge. Dovecot (2.2.27-3+deb9u2) expunges them.
