This doesn't seem to affect clients, but I'm seeing an occasional pop3 error in the log over the last week. Any ideas what is causing this?

[Dovecot] How to manipulate attachments with LDA?
by Piotr Szafarczyk - NetExpert 10 Jul '13

10 Jul '13

Hi All, I want to plug in a tool that will convert attachments somewhere into a mail delivery process (postfix->dovecot). I think deliver would be a good place to do it. Does it make sense? Could you direct me where I could read about how to do it please? Piotr Szafarczyk

[Dovecot] Have an issue with catch-all - Dovecot-lda andPostfix
by Joakim Ohlsson 10 Jul '13

10 Jul '13

Hi, I run dovecot version 2.1.7 and postfix 2.9.6. I'm using dovecot-lda as local delivery. I use virtual users and need to use catch-all for some of my domains. My problem when using catch-all is that I got a separate email for each recipient. As an example: If I send mail to: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org and have a catch-all which will send this mail to test(a)test.org. In this example I get 4 mails in my test(a)test.org inbox and in TO: field in the header I have all this four recipients: TO: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org. In my dovecot log: 2013-07-10 13:49:25 lda(test(a)test.org): Debug: Destination address: test(a)test.org (source: user@hostname) 2013-07-10 13:49:25 lda(test(a)test.org: Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX My question is if it's possible to receive just one mail instead of four? If I send the mail via Spamassassin I'll just receive one mail to test(a)test.org with TO: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org in the header. Thanks in advance Br Joakim # dovecot -n:

[Dovecot] Dovecot SLOW in imaptest without any apparent reason
by FABIO FERRARI 10 Jul '13

10 Jul '13

Hello, I'm migrating a mail server from a centos 5 cluster architecture to a centos 6 cluster architecture. The new cluster involves faster machines then the old cluster, and a virtual machine. I use dovecot-2.0.9-5.el6.x86_64, while the old cluster uses dovecot-2.0.1-1_118.el5. Tha mail server uses mysql for the users database, and a local ldap for authentication. The storage is also much faster in the new cluster: OLD SERVER: date; dd if=/dev/zero of=/cl/prova.bin bs=102400 count=10240; sync; date Wed Jun 26 15:43:53 CEST 2013 10240+0 records in 10240+0 records out 1048576000 bytes (1.0 GB) copied, 30.0202 seconds, 34.9 MB/s Wed Jun 26 15:44:28 CEST 2013 --> 1GB / 35 secs = about 29.25 MB/sec NEW SERVER: date; dd if=/dev/zero of=/cl/prova.bin bs=102400 count=102400; sync; date mar 25 giu 2013, 15.46.36, CEST 102400+0 records in 102400+0 records out 10485760000 bytes (10 GB) copied, 62,5143 s, 168 MB/s mar 25 giu 2013, 15.48.33, CEST [root@eta ~]# ---> 10GB / 117secs = about 85.47MB/sec An 'ls -l' in the user direcotry is also much faster, when the ldap/sssd cache is populated: OLD SERVER: real 0m8.540s user 0m1.229s sys 0m0.699s NEW SERER: real 0m3.938s user 0m0.250s sys 0m0.151s But my imaptest is much slower: ./imaptest user=XXXXXXX pass=XXXXXXX secs=120 seed=123 mbox=./dovecot-crlf OLD SERVER: Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1122 559 547 1121 1121 1568 136 900 1121 1121 2244 NEW SERVER Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 390 210 185 389 389 589 49 320 389 389 780 The configuration is exactly the same in the 2 clusters, that is: ----------- # 2.0.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-348.3.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.9 (Tikanga) xfs auth_cache_size = 1024 auth_cache_ttl = 21600 s auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no hostname = mail.unimore.it info_log_path = /var/log/dovecot.log lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:/cl/mail/vhosts/sms.unimo.it/%Ln/Maildir mail_plugins = $mail_plugins quota mailbox_idle_check_interval = 60 s mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot.masterusers driver = passwd-file master = yes } passdb { args = dovecot driver = pam } plugin { quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox is full) quota_rule = *:storage=200MB quota_rule2 = *:messages=100000 quota_rule3 = INBOX.Trash:storage=+100M quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=85%% quota-warning 85 %u quota_warning3 = messages=95%% quota-warning 95 %u quota_warning4 = messages=80%% quota-warning 80 %u setting_name = quota } postmaster_address = postmaster(a)unimore.it quota_full_tempfail = yes service anvil { client_limit = 199999 process_limit = 1 } service auth { client_limit = 21224 unix_listener auth-userdb { mode = 0600 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } process_limit = 10000 } service imap { process_limit = 10000 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 } } service pop3 { process_limit = 1024 } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { group = vmail user = vmail } user = dovecot } ssl_ca = </etc/pki/tls/certs/ca_unimore_tcs.pem ssl_cert = </etc/pki/tls/certs/mailposta1.pem ssl_key = </etc/pki/tls/certs/mailposta1.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_ssl = yes protocol lda { mail_plugins = $mail_plugins quota } protocol imap { mail_plugins = $mail_plugins } protocol pop3 { mail_plugins = $mail_plugins quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } ----------- Is anyone able to tell me what I have to check? thanks in advance Fabio Ferrari

[Dovecot] Strange Problems when deleting folders.
by Davide Bozzelli 10 Jul '13

10 Jul '13

Hi I'm experiencing a strange problem on my dovecot 2.0.21 setup. When i delete a folder "foo" it was correctly moved in the trash folder. If i try to delete from it the folder "foo" from the trash it gets renamed "foo1". If I try to dlete "foo1" it gets renamed foo11, and the operation could be continued figured out in an endless loop. This happens both from thunderbird and sogo (a webmail). Is it a known bug or a misconfiguration ? Thx in advance

[Dovecot] Migrating domain using IMAPc
by Breno Moreira 10 Jul '13

10 Jul '13

Hi list, I'm trying to do a domain migration using the imapc feature, but i'm having some problems and I really don't know what is happening. So if you guys could help me with a path to solve this, I will be glad. I'm using Dovecot 2.1.7 in a Debian Wheezy machine. The command I'm using is: dsync -Dv -o imapc_features=rfc822.size -o imapc_host=IP -o imapc_port=143 -o imapc_username='breno.moreira(a)mav.com.br' -o imapc_password='pass' -u breno.moreira(a)mav.com.br mirror imapc:/tmp/dsync-imapc and what I got with the logs is: doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module

[Dovecot] LMTP Proxy
by Cassidy Larson 10 Jul '13

10 Jul '13

Trying to figure out Proxying with LMTP to a few back end storage servers for quota checking before accepting email delivery on the front end nodes. If I connect to the back end server directly via telnet, everything works great. If I use a front-end server to proxy to the back end server, I don't get the same result. Running 2.2.4 on both front and back end servers. Any help would be appreciated. ------ backend dovecot.log: dovecot: lmtp(72274): Error: userdb lookup(user@host*masteruser): Disconnected unexpectedly dovecot: auth: Fatal: master: service(auth): child 72272 killed with signal 11 (core not dumped) ------ front end dovecot.log: dovecot: lmtp(7495): Debug: auth input: user=user(a)host.comnopassword=<hidden> host=<backend_server_ip> destuser= user(a)host.com*masteruser nologin=Y nodelay=Y proxy=Y pass=<hidden> port=2525 ------ front end dovecot.conf: lmtp_proxy = yes protocols = lmtp protocol lmtp { postmaster_address = postmaster(a)mydomain.com mail_plugins = quota passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } } service lmtp { client_limit = 5 executable = lmtp idle_kill = 0 process_limit = 0 process_min_avail = 0 protocol = lmtp service_count = 0 inet_listener lmtp { address = <frontend_server_ip> port = 2525 } } ------ backend dovecot.conf: auth_master_user_separator = * lmtp_rcpt_check_quota = yes passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql master = yes } userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } service lmtp { client_limit = 5 executable = lmtp -L idle_kill = 0 process_limit = 0 process_min_avail = 0 protocol = lmtp service_count = 0 inet_listener lmtp { address = <backend_server_ip> port = 2525 } } protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log postmaster_address = postmaster(a)infowest.com mail_plugins = quota }
