[Dovecot] IMAP proxy - can it detect parodying to itself?
by Graham Leggett 26 Nov '12

26 Nov '12

Hi all, I have some IMAP servers fronted with separate perdition processes, and it would be ideal if I could collapse this down to having dovecot do both the IMAP proxying and the IMAP serving at the same time on the same IP addresses. One of the fields in my LDAP entries contains the canonical name of the server that hosts their mailbox, and if I follow the manual at http://wiki2.dovecot.org/PasswordDatabase/ExtraFields#LDAP I could add the host field to enable proxying. My question is whether dovecot has the ability to notice whether dovecot is being asked to proxy to itself, in other words the value of "host" is the current dovecot server, and when this happens, ignore the proxy and just be a straight IMAP server, because the user has connected to the right box already. Is this possible? Regards, Graham --

Re: [Dovecot] doveadm fails with passdb authentication binds (dovecot 2.0.16)

Hello, >> # doveadm mailbox list -u user001 >> doveadm(user001): Error: user user001: Auth PASS lookup failed >> doveadm(user001): Fatal: passdb lookup failed > Are you running this on a Dovecot proxy? It looks like doveadm wants to do a passdb lookup to find out which server should handle this user. Passdb lookups don't work with LDAP binding. But if everything else works then I think you simply shouldn't have enabled doveadm proxying. So, set doveadm_proxy_port back to 0? thank you Timo, setting doveadm_proxy_port to 0 did the trick.

[Dovecot] Missing Messages on IOS device
by David Morsberger 26 Nov '12

26 Nov '12

I just converted my old server running UW/Panda to a Mac Mini Server running Mountain Lion (ML) Server. I'm using the postfix / dovecot setup provided by Apple. My IMAP clients are not showing all my emails. The Mail App on my iPhone and iPad is behaving the worse. I can see the emails that are not showing up in the cur directory. The ML Mail App is stating there are 3854 emails in my INBOX. There are 3948 files in the 'cur' directory ('ls cur | wc -l' returns 3948). Other mailboxes and directories have the same behavior. I'm not sure what to expect here. My method of conversion was to bulk copy (drag and drop) all the messages from one the UW server to the Dovecot server using the Apple Desktop Mail App in Mountain Lion. Any idea why these messages are not showing up on my devices and how I can get them to show up? bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd --version 2.0.19apple1 bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd -n # 2.0.19apple1: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 hfs aps_topic = com.apple.mail.XServer.fc3bb7c3-c8ef-4fe2-aff3-95ecd927fb11 auth_mechanisms = cram-md5 x-plain-submit plain login apop digest-md5 auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %n default_internal_user = _dovecot default_login_user = _dovenull disable_plaintext_auth = no first_valid_gid = 6 first_valid_uid = 6 mail_access_groups = mail mail_location = maildir:/Library/Server/Mail/Data/mail/%u mail_log_prefix = "%s(pid %p user %u): " mail_plugins = quota zlib fts fts_sk managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mdbox_rotate_size = 200 M passdb { args = /Library/Server/Mail/Config/dovecot/submit.passdb driver = passwd-file pass = yes submit = yes } passdb { driver = od } plugin { fts = sk quota = maildir:User quota quota_warning = storage=100%% quota-exceeded %u sieve = /Library/Server/Mail/Data/rules/%u/dovecot.sieve sieve_dir = /Library/Server/Mail/Data/rules/%u } postmaster_address = postmaster(a)mini.mmpcrofton.com protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { extra_groups = _keytabusers idle_kill = 15 mins unix_listener auth-userdb { user = _dovecot } } service dns_client { unix_listener dns-client { mode = 0600 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } service_count = 0 } service imap { client_limit = 5 process_limit = 200 service_count = 0 } service lmtp { unix_listener lmtp { mode = 0600 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { client_limit = 5 process_limit = 200 service_count = 0 } service quota-exceeded { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-exceeded.sh unix_listener quota-exceeded { group = mail mode = 0660 user = _dovecot } user = _dovecot } service quota-warning { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-warning.sh unix_listener quota-warning { group = mail mode = 0660 user = _dovecot } user = _dovecot } ssl_ca = </etc/certificates/*.chain.pem ssl_cert = </etc/certificates/*.cert.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL:!ADH:!eNULL ssl_key = </etc/certificates/*.key.pem ssl_key_path = /etc/certificates/*.key.pem syslog_facility = local6 userdb { args = partition=/Library/Server/Mail/Config/dovecot/partition_map.conf enforce_quotas=no driver = od } verbose_proctitle = yes protocol lmtp { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol lda { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol imap { imap_id_log = * imap_id_send = "name" * "version" * mail_max_userip_connections = 20 mail_plugins = quota zlib fts fts_sk imap_quota imap_zlib imap_fts urlauth } protocol pop3 { mail_max_userip_connections = 6 }

[Dovecot] sieve-extprograms strips Return-Path headers
by Ben Morrow 25 Nov '12

25 Nov '12

The sieve-extprograms extension strips Return-Path headers before passing mail off to the external program. The patch to remove this behavious is trivial (and attached), but since it appears to be deliberate I felt I should investigate further. I believe this is basically a cut-and-paste error. The code to strip Return-Path has been there since the sieve-pipe plugin for Dovecot 1.x, and I believe it was copied from the equivalent code in the 'redirect' action for passing mail off to sendmail(8). In that case, stripping Return-Path is correct, since the message is being resubmitted for delivery (by SMTP or otherwise), and the last step of the new delivery will (should) add a new Return-Path header with the new envelope information. In the case of sieve-extprograms, though, the filtering is happening post-delivery, so a stripped Return-Path will never be replaced. Ben

[Dovecot] Proxy to join two accounts
by Tomek 23 Nov '12

23 Nov '12

Hello, I have server with IMAP on dovecot for user mails and second server on archiveopteryx as mail archive. I'm wondering if it's possible to make some sort of proxy to these two servers in way where: - dovecot server will be main IMAP service with INBOX, etc - I want archiveopteryx account to be something like shared folder with read only access (no delete, no move, etc) in path ex. /archive/user.name - this proxy mappings should allow adding few archive accounts to one user (in case of people replacement) + it will be cool if this mappings could be defined in database so I could write tools to manage archive access for bosses. Is such case possible to achieve with dovecot (any howto or example would be very helpful)? If not - do you know any proxy tools that could allow such configuration? Thanks for any help. Regards, Tomek.

[Dovecot] v2.1.10: Director director_servers order issue
by Bertrand Jacquin 23 Nov '12

Hi, I'm setting up an IMAP/POP cluster using dovecot director for some NFS reasons and I'm getting some troubles with director_servers directive. Configuration is shared on both nodes : director_servers = 10.0.50.50 10.0.50.51 director_mail_servers = 192.168.0.150 192.168.0.151 director_user_expire = 15 min service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0600 user = $default_login_user } unix_listener director-userdb { mode = 0600 } inet_listener { port = 9090 } } service ipc { unix_listener ipc { user = $default_login_user } } Here 10.0.50.50 is node1, 10.0.50.51 is node2 # ring status on node1 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never # ring status on node2 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never self is the same on both nodes, and that generate some cases that can be observed on logs : # logs on node1 dovecot: director: Error: Remote director thinks it's someone else (connected to 10.0.50.51:9090, remote says it's 10.0.50.50:9090) And this is true, TCP packet contain bad DATA : # tcpdump -i eth0 -nn src host 10.0.50.51 and port 9090 -s 0 -w - -l | strings | egrep '^ME' ME 10.0.50.50 9090 # logs on node2 dovecot: director: Error: connect(10.0.50.51:9090) failed: Invalid argument Invalid argument is present as bind() is not done with the appropriate IP : # strace -p 6063 -fF -s 1024 -e trace=bind,connect bind(28, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("10.0.50.50")}, 16) = 0 connect(28, {sa_family=AF_INET, sin_port=htons(9090), sin_addr=inet_addr("10.0.50.51")}, 16) = -1 EINVAL (Invalid argument) Also, during this time, CPU is ~100% used. bind() is done with node1 IP address. I also tested using a DNS : director_servers = director-all director-all is two A entries, first containing 10.0.50.50, second 10.0.50.51 and the result here is exactly the same. Using two configurations : # director_servers on node1 director_servers = 10.0.50.50 10.0.50.51 # director_servers on node2 director_servers = 10.0.50.51 10.0.50.50 Give the same result as showed before : # ring status on node1 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never # ring status on node2 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never It seems that first sorted entry in director_servers is considered as "self". I'm using dovecot 2.1.10-0~auto+55 debian package from rename-it repository. Thanks for your help. -- Beber

[Dovecot] whoson plugin for 2.0
by Chuck Cochems 23 Nov '12

23 Nov '12

I have found a plugin at ftp://ftp.ufanet.ru/pub/boco/dovecot/whoson-plugin/ I was able to make it function on a dovecot 1.2.8 server, by changing __attr_unused__ to ATTR_UNUSED and strlcpy to i_strocpy (since glibc doesn't HAVE strlcpy, on purpose). However, it doesn't work with 2.1 this is, of course, because getenv() no longer functions lie it used to in plugins. so i need a replacement for getenv("IP") and getenv("USER") to make this work. i know, pop before SMTP is stupid, but the isp i'm doing this for hs customers that have used pop before smtp for ages. so I MUST make a whoson plugin. as i said, the remote ip and the email address are required to interface with whoson. (this is superior to DRAC, which just opens the IP)
