[Dovecot] Denying authentication
by Romer Ventura 13 Jan '11

13 Jan '11

Hello, I've been running dovecot for over 3 years now and it works with no problems. I have it setup so that it authenticates users against Active Directory via LDAP and so far no problems. What I would like to know is if there is any way that I could deny access for users trying to access email via cellphones or email clients outside the company. I can close everything since there are a few users that need to get emails from outside the company via cell phone of email clients. I was thinking if there was a way to lets say create a group in AD named: "remote-email" that will allow connection and authentication from any network, any user not in that group will only be able to authenticate if the source is 192.168.xx.xx/24. Is this possible? Maybe not with Dovecot, but maybe someone else has any ideas..? Thanks -------- Romer Ventura

[Dovecot] Making shared folders "unmovable"
by Dave 13 Jan '11

13 Jan '11

I have set up an area of shared folders with Dovecot 1.2 that is accessed by several people (by way of one account, and everyone who logs in sees these same folders), and the only problem with this setup is that occasionally somebody moves one of the folders underneath another folder or somewhere else in the folder structure, and this sometimes disrupts some automatic procmail filters and the like. Is there a way to keep folders in a shared setup such as this "static" or "unmovable" so that the users can't disrupt the structure? Like, where the folder structure itself can't be changed, but new messages can still come in to the folders? David

[Dovecot] How do folk . . . Aggregate system mail from LAN machines?
by Ron Leach 12 Jan '11

12 Jan '11

List, good evening, Running Dovecot for external email, but not yet worked out how (best) to aggregate 'system' mail from other machines on the LAN. By system mail, I mean mails generated by the OS or by applications, and addressed to root, or 'some admin user', etc. Ideally, these would be seen by 'root' or 'some admin user' or whoever on our existing Dovecot/IMAP system. Our scale is not large, we only have 5 servers on the LAN doing various things. I wondered how other Dovecot users do this. I've thought of 3 possibilities: 1. Install Dovecot on each LAN machine, and use Fetchmail to retrieve the messages using POP so that local mail stores were emptied. 2. Perhaps, use a 'forwarding' mechanism of some sort on each LAN machine, but that would require an MTA on each LAN machine, would it not? 3. I wondered whether /etc/alias, mentioned in a recent post by Simone Caruso, might help though again, presumably, requiring an MTA on each LAN machine. What do you do? regards, Ron

[Dovecot] Question about lda & auth_socket_path
by Jahnke-Zumbusch, Dirk 12 Jan '11

12 Jan '11

Hi all, storing e-mails (using postfix) via dovecot-lda fails and I assume this is related with a auth_socket configuration problem. But I am at a dead end, so perhaps anybody has got a hint for me: This is dovecot-2.0.8 on Solaris 10: 10-auth.conf and its include: ----------------------------- ... userdb { driver = static args = uid=104 gid=104 home=/some/path/%u } Relevant parts of 10-mail.conf: --------------------------------- ... auth_socket_path = /var/run/dovecot/auth-userdb Relevant parts of 10-master.conf: --------------------------------- ...service auth { unix_listener auth-userdb { mode = 0644 user = vmail #group = } } service auth-worker { user = root } Relevant parts of 15-lda.conf: --------------------------------- ... protocol lda { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins } # ls -l /var/run/dovecot/auth-userdb srw-r--r-- 1 vmail root 0 Jan 12 15:49 /var/run/dovecot/auth-userdb Using dovecot-lda for mail delivery or doveadm for user inquirement fails: via debug_log_path: ------------------- Jan 12 16:04:14 auth: Debug: Loading modules from directory: /dovecot/code/dovecot-2.0.8/lib/dovecot/auth Jan 12 16:04:14 auth: Debug: passwd-file /store1/db/masterusers.passwd: Read 1 users Jan 12 16:04:14 auth: Debug: master in: USER 1 djahnke service=lda Jan 12 16:04:14 auth: Debug: password(djahnke): passdb doesn't support credential lookups Jan 12 16:04:14 auth: Debug: master out: FAIL 1 Jan 12 16:04:14 lda: Debug: auth input: via syslog: ----------- Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] auth: Error: static(djahnke): passdb doesn't support lookups, can't verify user's existence Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] lda: Error: user djahnke: Auth USER lookup failed Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.crit] lda: Fatal: Internal error occurred. Refer to server log for more information. When I use "allow_all_users=yes" everything works fine, so I think somehow the communication with the socket fails. I cannot see what I have missed :-( Any suggestions what I should look for / configure ?

[Dovecot] mail quota dovecot 1.2.15-3
by J4 12 Jan '11

12 Jan '11

Dear all, I am attempting to enforce quota with Dovecot 1.2.15-3 using LDA for deliver. I use smtp-source (postfix) to deliver large messages but the quota is never noticed. The webmail interface is Roundcube, and the admin is performed using Postfixadmin. I have not looked into the postfix portion for quota, yet. Is there something that I have missed from the configuration?

[Dovecot] Refilter Mailboxes via Sieve - Missing delivered-to header
by Dieter Knopf 12 Jan '11

12 Jan '11

Hello, i already read http://wiki.dovecot.org/HowTo/RefilterMail but it won't work here :( I have many old mails in my folders and need to refilter many of them. But there are many mails without a delivered-to-header. What can i do? Error: Configuration error: envelope_recipient specified header missing (delivered-to:1) Would be okay if getmail would just skip the mail, but it cancels. Not sure if there is any way around. This is the config: [retriever] type = MultidropIMAPSSLRetriever envelope_recipient = delivered-to:1 server = foo port = 993 username = foo password = foo mailboxes = ("INBOX.REFILTER",) move_on_delete = INBOX.trash [destination] type = MDA_external path = /usr/lib/dovecot/deliver arguments = ("-e", "-f", "%(sender)", "-d", "%(recipient)") user = vmail group = vmail [options] delete = true recieved = false delivered_to = false verbose = 2 I'm using virtual users, so i must use Multidrop. Thanks

[Dovecot] Connection queue full on my directors
by Jan-Frode Myklebust 11 Jan '11

11 Jan '11

I finally upgraded to v1.2.16 on my backend servers, with ldap instead of previously mysql, and put a couple of dovecot v2.0.8 directors in front of them (used haproxy previously). It seemed to work OK initially, but after a few hours we got bit by "Connection queue full" problems on the directors. So I now set default_process_limit=512 and also: service anvil { client_limit=1027 } since dovecot said that was now required. Things seems to be working, but I'm afraid default_process_limit=512 is too low: $ ps -ef|grep dovecot/pop3-login|wc -l 192 $ ps -ef|grep dovecot/imap-login|wc -l 472 so looks like I'm quite close to hitting this limit for my imap logins. We will eventually put up some webmail servers (using imapproxy to keep connections alive), that will be connecting over these directors. Then we will expect to have a lot more active imap sessions over these directors. Should we just keep increasing default_process_limit, or per service process_limit, and follow dovecots warnings about client_limits for auth/anvil.. or will we be getting into other problems like running out of file descriptors? Are there any max'es we should expect to run into ?

[Dovecot] Dovecot - AllowGroups option
by Jacob Neergaard Pedersen 11 Jan '11

11 Jan '11

Hi, I'm trying to control access to different services on an Debian server using /etc/group. So that a user I create for FTP usage doesn't fill up my server with IMAP folders or samba garbage. Services like proftpd have: "AllowGroup ftpgroup" sshd have "AllowGroups sshgroup" And samba have "valid users = @smbgroup" But I can't find the correct option in Dovecot (/etc/dovecot/dovecot.conf) Do anyone have the magic option or a workaround thats doesn't envolve maintaining seperate user databases and password? (I know its needed for samba but besides that) /Neergaard
