[Dovecot] version difference understanding
by upen 05 Mar '11

05 Mar '11

Hello, I am in process of setting up an IMAP server (with postfix SMTP), I installed RHEL 5.5 on my server and found that version of dovecot is 1.x.x while when I checked online RHEL 6 is version is 2.x.x. Can someone please tell me if these two versions are still in development or 1.x.x is very old and must be replaced by 2.x.x version? Also are there any special features in 2.x.x or 1.x.x that makes it better than other? I see similar things for postfix package but I understand this is not the place to ask postfix Qns, Appreciate your help! ~A

[Dovecot] All mails unread after short while
by francwalter＠gmx.net 05 Mar '11

05 Mar '11

Hello, I have on Ubuntu 8.04 Postfix 2.5.1 and Dovecot 1.0.10. The mails are saved in maildir format. In one account on my server all mails are unread all the time. If i set them as read in my client (IMAP with Mac Mail 4.4 or IMAP with Squirrelmail, it doesn’t matter) they seem to be checked as read for some minutes or less, but very soon they are unread again, so i guess, only my client thinks that they are read, but after the next check, the client reads again that they are unread. Now i don’t know where to look or change the “Has been read”-Flag in the maildir-directory. Is it in some file or where is it, the flag? It is only one account, the other accounts on the same domain and on other domains are working quite well. Maybe it is only after a Squirrelmail update last week, but I am not sure. Thank you, Kind Regards, frank walter

[Dovecot] Is the trunk version of Pigeonhole still broken or am I missing something?
by interfaSys sàrl 05 Mar '11

05 Mar '11

Things broke a couple of months back and I thought I had caught the repository at a bad time, but trying again today, after having seen that people had been working on it recently, bore the same result. ../../../../libtool: line 2072: cmd-vacation.c: command not found I'm simply syncing with the repository and using autogen, configure and make. Are there any other steps required? Olivier

[Dovecot] v2.0.10 released
by Timo Sirainen 04 Mar '11

04 Mar '11

http://dovecot.org/releases/2.0/dovecot-2.0.10.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.10.tar.gz.sig I thought it was finally time to make a new v2.0 release. Or probably it was a while ago already, but I've been a bit lazy this year. Maybe it's because this is the first time in last 5 years when all branches of Dovecot have been quite stable and I haven't been stressing on it. Of course there are some v2.0 features that still have some bugs, but few people are complaining about them. v2.1 development branch also appears to be pretty good shape. I'm hopeful that v2.1.rc1 will be out before summer. * LMTP: For user+detail@domain deliveries, the +detail is again written to Delivered-To: header. * Skip auth penalty checks from IPs in login_trusted_networks. + Added import_environment setting. + Added submission_host setting to send mails via SMTP instead of via sendmail binary. + Added doveadm acl get/set/delete commands for ACL manipulation, similar to how IMAP ACL extension works. + Added doveadm acl debug command to help debug and fix problems with why shared mailboxes aren't working as expected. - IMAP: Fixed hangs with COMPRESS extension - IMAP: Fixed a hang when trying to COPY to a nonexistent mailbox. - IMAP: Fixed hang/crash with SEARCHRES + pipelining $. - IMAP: Fixed assert-crash if IDLE+DONE is sent in same TCP packet. - LMTP: Fixed sending multiple messages in a session. - doveadm: Fixed giving parameters to mail commands. - doveadm import: Settings weren't correctly used for the import storage. - dsync: Fixed somewhat random failures with saving messages to remote dsync. - v2.0.9: Config reload didn't notify running processes with shutdown_clients=no, so they could have kept serving new clients with old settings.

[Dovecot] /etc/pam.d/dovecot missing? during high load
by Douglas Mortensen 04 Mar '11

04 Mar '11

This morning on our newly built server, the following was logged twice: auth: Error: pam(username,127.0.0.1): pam_authenticate() failed: Authentication failure (/etc/pam.d/dovecot missing?) This also happened to be during a time of 100+ imap-login processes, where we were seeing: master: Warning: service(imap-login): process_limit reached, client connections are being dropped The initial error was correct, in that I had not yet created /etc/pam.d/dovecot. I have since created the file. However, we brought this server into production yesterday & there were no complaints, nor was the error logged besides twice this morning within 3.5 minutes of eachother. In looking at pam documentation, it is my understanding that when a service (dovecot) does not have its own file existing under /etc/pam.d, then pam will instead use the settings from /etc/pam.d/others as defaults. This seems logical to me, and would explain why things have been working fairly well with no errors regarding pam (other than the 2 logged this morning). However, what this does not explain, is why dovecot auth logged about the file missing at all. I can only guess that it was related to logins being dropped due to high load, and was incorrectly logged?? For reference, my current /etc/pam.d/dovecot is: auth required pam_unix.so nullok account required pam_unix.so My current /etc/pam.d/other is: @include common-auth @include common-account @include common-password @include common-session Which results in (confirmed via : grep -v ^# common-auth common-account common-password common-session) auth [success=1 default=ignore] pam_unix.so nullok_secure auth requisite pam_deny.so auth required pam_permit.so account [success=1 new_authtok_reqd=done default=ignore] pam_unix.so account requisite pam_deny.so password [success=1 default=ignore] pam_unix.so obscure sha512 password requisite pam_deny.so password required pam_permit.so session [default=1] pam_permit.so session requisite pam_deny.so session required pam_permit.so session required pam_unix.so So there definitely is quite a difference between the dovecot pam file I created (based on the dovecot2 wiki), and the system default (other). I don't know whether this could have been related, so I figured I'd share. Otherwise, I'm running dovecot 2.0.9 compiled from source. dovecot -n at the time of the pam errors was probably: # 2.0.9: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0 auth_debug = yes auth_mechanisms = plain login disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_location = maildir:~/ mail_privileged_group = mail passdb { driver = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } ssl_cert = </etc/ssl/certs/jlgray.com.cer ssl_key = </etc/ssl/private/jlgray.com.key userdb { driver = passwd } Thanks, - Doug Mortensen Network Consultant Impala Networks Inc CCNA, MCSA, Security+, A+ Linux+, Network+, Server+ . www.impalanetworks.com P: (505) 327-7300 F: (505) 327-7545

[Dovecot] logging issues w/ login_max_processes_count on 1.x
by Douglas Mortensen 04 Mar '11

04 Mar '11

Today I found our dovecot 2.x gracefully logged: dovecot: master: Warning: service(imap-login): process_limit reached, client connections are being dropped I am confident that we had the very same problem on our previous dovecot 1.x box. Of course with dovecot 1.x, the same relative setting is login_max_processes_count. I believe that I turned up all dovecot logging & debugging to the max (also checked with the 1.x wiki), but nothing was ever logged relating to this. Does anyone know whether there is a way to get dovecot 1.x to log this type of error?

[Dovecot] penalty configuration and proxy servers
by Mark Zealey 04 Mar '11

04 Mar '11

Hi there, I've had a look through the wiki and a quick look through the source for penalty configurations (dovecot 2.0.9) but I've not found anything to do with configuration options for this functionality. I'm basically wanting to disable a particular host/subnet from the penalty setup. In our case we have some webmail servers that do get attacked however most of the traffic is legitimate so I'd rather that the user experience was faster (ie not having a few seconds of delay on login) than that we slowed down attacks from them. On a similar note; is it possible to do the per-ip login limit in the auth level rather than the imap/pop level? I ask this as we've just implemented a proxy setup whereby we have two frontend proxy servers that then dispatch to backend servers specified in the database. So, the backend servers do the actual imap/pop sessions however we now don't see the remote ip addresses so it becomes difficult to limit abusive users. The 'doveadm who'/process listing code also doesn't work on the proxy servers even though dovecot knows who logged in and forwards the connection through to the backend servers. None of these features/suggestions are show-stoppers; dovecot is a great program however they're more suggestions of ways it would be useful for us to improve the software. Thanks, Mark

Hi guys Im viewing how to repair a problem using a postfix platform with openldap and dovecot. This is the problem: -When I create a new user inside openldap with mail account appears correctly inside ldap but when I access first time appears inside /var/spool/dovecot/ the folder of account bad.
