[Dovecot] POP3 Setup help
by Thomas I Higgins 09 Oct '13

09 Oct '13

I am lost as to what I am missing. I am setting up dovecot 2.0.9 on a RHEL 6.4 machine as provided by my provider. I have IMAP up and running, and I have POP3 up and running. Testing confirms this. Also, if it makes a difference, I enabled dovecot as my LDA. Sendmail was setup as well due to our 1.x version using it and I though I had to. Anyway, everything is working perfectly with the services, except the mail is sending to the wrong location for POP. I am trying to use Maildir for both services, but it keeps delivering the POP3 mail to /var/spool/mail/u% instead of to Maildir as specified in the configuration files. I have rechecked every setting at least twice and still can't see what I am doing wrong. I suppose I can use mbox and redirect after making the appropriate namespace changes, but that has it's own potential drawbacks and seems more like a kludge than the correct way around this (unless I misunderstand how it should work). Can anyone point me in the right direction on how to fix this? Thanks in advance, Thomas Higgins

Hi everybody. Hi I'm tryingto use CAS for authenticating in dovecot. I have installed pam_cas and when I try castest i get "<cas:authenticationSuccess>" for my service (imaps://mywebmail.com) But when I actually try to login, dovecot uses the PT from the cas server as password. Any ideas what I'm missing? Thanks a lot.

Looking at http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy methinks you want to replace "starttls=y" with "ssl=yes". Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Proxy to gmail not working
by Alex Wanderley 07 Oct '13

07 Oct '13

Hi, I've been trying to build a password forwarding proxy to Gmail without success... The SSL connection to Dovecot is happening no problem (as far as I can tell), but for some reason the conversation between Dovecot and Gmail is getting timed out. I know this is supposed to be simple... :-( But could somebody please give me some help by pointing what I'm not doing right? No matter how much I've been researching about this, I can't find the solution.

[Dovecot] Replication: long detalys
by Lucas Rothamel - Eye Catching Webdesign 07 Oct '13

07 Oct '13

Hello everybody, I am running dovecot 2.1.7 on Debian Wheezy on two servers with replication set up, MTA is postfix. The idea is to have a redundant mail system so that when one server fails, users can continue using the other server (failover of POP/IMAP through DNS redirection). Servers are called srv06 and srv07: Below is the dovecot config, both servers have identical config, only the replica srv0x address is different. I read to put this line into 10-mail.conf and I did: mail_plugins = $mail_plugins notify replication My Problem: When E-Mail arrives on one server, it is only available on the other server many hours later. Same behaviour in both directions. This means I see different mailboxes via IMAP depending on which server I connect to - in theory I want the client not to be able to tell which server it is connected to. dovecot -n: # 2.1.7:

[Dovecot] retr errors
by Bill Morgan 07 Oct '13

07 Oct '13

My ISP uses Dovecot and I have had an ongoing problem for a while using several email clients. Sometimes the response to a retr request is mal-formed. The expected response "+OK nnn octets" is not returned. The response looks like it started somewhere in the message headers. Sometimes a retry can clear the problem but I usually need to delete the first message via a putty session. The problem, when present, is always on the first message. Never seen it in the middle of a series of messages. This problem has been seen on different machines, different versions of Windows, at home and on the road. I have wireshark traces showing good and bad sessions.... ====================== stat +OK 93 1000437 retr 1 +OK 6946 octets Return-path: ..... ========================= retr 1 of blahblah(a)blah.com designates 2607:f8b0:4001:c03::235 as permitted sender) smtp.mail=blahblah(a)blah.com; dkim=pass header.i=(a)blah.com Reply-To: android-developers(a)googlegroups.com Precedence: list Mailing-list: ...... ================== My ISP has been non-helpful. Any ideas how I can track down the problem? Thanks Bill

[Dovecot] Yet another going from 1.2 to 2.X question: authentication
by Mauricio Tavares 07 Oct '13

So in 1.2.9 I had something like this: [...] socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtual # User running Dovecot LDA's deliver } } # Dovecot as SASL Auth socket listen { client { path = /var/spool/postfix/private/dovecot-auth mode = 0660 user = postfix group = postfix } } I see I can, per http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL, setup the sasl entry as # Dovecot as SASL Auth service auth { unix_listener /var/spool/postfix/private/dovecot-auth mode = 0660 user = postfix group = postfix } what about the lda? From http://wiki2.dovecot.org/LDA I take it would be as simple as service auth { unix_listener auth-userdb { mode = 0600 user = virtual # User running Dovecot LDA's deliver } } Am I correct?

[Dovecot] couple of errors on new setup

I have stood up a new test mail server as an upgraded version of my existing mail server. I have been fairly consistently getting two types of error messages. I'm thinking they may be related permissions issues, but I can't figure out what their problem is. Oct 4 12:45:47 digory dovecot: imap(guenther): Error: file_dotlock_open() failed with file /home/guenther/mail/ForUs/.imap/Home/dovecot.index.log: Resource temporarily unavailable Oct 4 12:46:16 digory dovecot: imap(guenther): Error: file_dotlock_open(/home/guenther/mail/ForUs/PCS/.imap/PCS misc/dovecot.index.log) failed: Permission denied (euid=500(guenther) egid=500(guenther), access(/home/guenther/mail/ForUs/PCS/.imap/PCS misc/dovecot.index.log, 4) failed: No such file or directory) Here are my specifics: OS: CentOS 6.4 - 2.6.32-358.11.1.el6.x86_64 MailScanner: 4.84.6 Postfix: 2.6.6 DoveCot: 2.2.4 NFS v4 (both the mail spool and /home are NVS v4 mounts to file server) Here are the non-default settings: dovecot -n # 2.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.11.1.el6.x86_64 x86_64 CentOS release 6.4 (Fina auth_verbose = yes disable_plaintext_auth = no mail_access_groups = users,guenther mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/postfix/ssl/xxxxxxxxxx.crt ssl_key = </etc/postfix/ssl/xxxxxxxxxx.key userdb { driver = passwd } verbose_ssl = yes Thanks -- Dean Guenther
