Moving a local domain to sql
by ＠lbutlr 22 Apr '15

22 Apr '15

I have a domain that current maps to local users that I want to move into the mysql maps with all the other domains, but I am unsure of the best way to proceed with this. For example, my mail server is covisp.net and my personal domain is kreme.com, and currently kremels(a)kreme.com maps to the local user kremels. I want it to map to the existing mysql database as “kernels(a)kreme.xn--com-9o0a. (For example only, I’m not moving kreme.com, I am too dependent on procmail for all my list processing). Once I setup the user account in the mysql database do I just move the Maildir from /home/kremels to /usr/local/virtual/kremels(a)kreme.com/ and reload dovecot? -- I leave symbols to the symbol-minded - George Carlin

dovecot efficient use of resources
by shouddy＠enet.cu 22 Apr '15

22 Apr '15

I just started a heavy load imap service and everything fitted OK in functional terms. The problem comes whith stress tests, I have no problem in the directors line. But my doubt comes whether the backends are using efficiently the resources assigned or not. The main goal is to maximize the concurrency without affect the integrity of operations. My question is: Is there a rule for relating the amount of computing resources (RAM, Processor) with the number of simultaneous connections to an IMAP/POP3 server running dovecot? I had made all the adjustmens for high performance in dovecot according to the docs and O.S specs Backend's hardware Processor: AMD Opteron(tm) Processor 6136 RAM: 16 GB HDD: Enought for testing I'm confident the NFS layer is not making noise (yet). Comparing the results, the output of tests are giving consistent numbers using local file systems (all of them properly tuned) I have run the tests with imaptest but even with 100 clients I'm having system's max load of 46 stable. I have the sense that memory is not using properly (2GB at most from 16GB). Thank you so much in advance, would be grateful for any help Conf below Dovecot version 2.2.10 doveconf -n # OS: Linux 3.10.0-123.20.1.el7.x86_64 x86_64 Red Hat Enterprise Linux Server release 7.0 (Maipo) nfs4 auth_mechanisms = plain login default_client_limit = 4000 disable_plaintext_auth = no listen = * mail_fsync = always mail_gid = 500 mail_location = maildir:/var/vmail/mailboxes/%d/%8n/%n:INDEX=MEMORY mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 500 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 mmap_disable = yes 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 { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { client_limit = 14400 service_count = 0 unix_listener auth-userdb { group = vmail mode = 0640 user = vmail } } service doveadm { inet_listener { port = 24245 } } service imap-login { client_limit = 1000 process_limit = 100 process_min_avail = 16 service_count = 0 vsz_limit = 512 M } service imap { process_limit = 7000 service_count = 0 } service pop3-login { client_limit = 1000 process_limit = 100 process_min_avail = 16 service_count = 0 } service pop3 { process_limit = 7000 service_count = 0 } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_max_userip_connections = 1000 } local 172.28.200.0/24/24 { doveadm_password = secret }

Please help: error after upgrade to version 2.1.16
by Harald Langner 18 Apr '15

18 Apr '15

Hallo I can not find a forum at dovecot.org and I get a problem I can not solve. After Updating to the version dovecot2 2.1.16 I can no more get eMails with my eMail-client. All has been working fine before. Server: FreeBSD 10.0-RELEASE-p18, with perl 5, version 18, subversion 4 (v5.18.4) It seems it is an authentication problem with my server. The errors are: #cat dovecot.log Apr 17 22:19:37 imap-login: Error: Timeout waiting for handshake from auth server. my pid=41810, input bytes=0 Apr 17 22:19:58 auth: Error: auth: environment corrupt; missing value for DOVECOT_ Apr 17 22:19:58 auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address Apr 17 22:19:58 master: Error: service(auth): command startup failed, throttling for 60 secs Apr 17 22:24:04 auth: Error: auth: environment corrupt; missing value for DOVECOT_ Apr 17 22:24:04 auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address Apr 17 22:24:04 master: Error: service(auth): command startup failed, throttling for 60 secs I have google and has nothing found about "..environment corrupt; missing value for DOVECOT_" and about "auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address" I have make a reinstall - but doesn't help. I get the same error. I have not forget to create new certs with the dovecote shell-script after installation. I'm using passwd (virtual users). Make a cat on passwd shows that it is not empty. Also the date of the file show that the update installation has it not changed. So I have not create the dovecot users again. here are some other logs: #cat dovecot-info.log Apr 17 22:29:03 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 1 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS handshaking Apr 17 22:29:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 30 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS Apr 17 22:29:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 30 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS #cat dovecot-debug.log Apr 17 22:30:03 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Apr 17 22:30:03 auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat Apr 17 22:34:01 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Apr 17 22:34:01 auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat Apr 17 22:34:01 imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client certificate A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [85.181.222.126] ######################################################################################## My configuration is sendmail(MTA) -> procmail(LDA) -> dovecot(IMAP) with TLS and Maildir (no DB) Authentification been done with dovecot password file (no real user, no OpenLDAP, no other DB-User) #dovecot -n # 2.2.16: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.0-RELEASE-p18 amd64 ufs auth_debug = yes auth_mechanisms = digest-md5 plain login auth_verbose = yes auth_verbose_passwords = plain base_dir = /var/run/dovecot/ debug_log_path = /var/log/dovecot-debug.log default_internal_user = vmail default_login_user = vmail deliver_log_format = msgid=%m: %$ %f %s disable_plaintext_auth = no first_valid_uid = 1000 hostname = swdevil.de info_log_path = /var/log/dovecot-info.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /var/log/dovecot.log login_greeting = IMAPd ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_access_groups = mailnull mail_debug = yes mail_location = maildir:/home/vmail/%d/%n/:INBOX=/home/vmail/%d/%n/.INBOX mail_plugins = " virtual" mail_temp_dir = /tmp/mail namespace inbox { inbox = yes location = prefix = } passdb { args = scheme=DIGEST-MD5 username_format=%n /usr/local/etc/dovecot/pass driver = passwd-file } service auth-worker { group = wheel user = root } service imap-login { group = dovenull inet_listener imap { port = 0 } inet_listener imaps { port = 993 } } service imap { process_limit = 100 } service pop3-login { group = dovenull inet_listener pop3 { port = 0 } inet_listener pop3s { port = 0 } } service pop3 { process_limit = 100 } ssl = required ssl_cert = </usr/local/etc/dovecot/certs/dovecot_ssl_crt.pem ssl_key = </usr/local/etc/dovecot/certs/dovecot_ssl_key.pem userdb { args = uid=vmail gid=vmail home=/home/vmail/%d/%n driver = static } verbose_proctitle = yes verbose_ssl = yes protocol pop3 { pop3_uidl_format = %08Xu%08Xv } Many thanks for Your advice what could be wrong.

Problem: mail moved by thunderbird script is invisible to mail clients, but in cur directory
by David Gessel 18 Apr '15

18 Apr '15

Over the last year I've had a script moving old mail (120 days) into my annual archive folder. This is the first year I've done this with Dovecot, previously it was running against Cyrus. There's nothing particularly clever: a few conditions to match, then "move message to" the appropriate archive folder. There's one for every year from 2000 to 2015. 2015 is just barely ahead of need. 2014 has about a year's mail in the cur directory. The 2000-2013 folders were filled by Cyrus and were migrated over using IMAP Migrate. They're fine, and read normally. The 2014 layout looks normal to me # ls cur dovecot-uidlist dovecot.index.cache dovecot.index.log.2 new dovecot-keywords dovecot.index dovecot.index.log maildirfolder tmp Permissions are the same as every other folder, as is owner: drw-r----- 2 vmail vmail 9.6K Apr 12 21:13 cur and # ls | wc -l 9822 I've checked with Thunderbird, Mulberry, Claws, and Sylpheed - none can read the directory. The files look normal: 2014/cur 1426411329.M123928P26360.host.domain.com,S=3523,W=3591:2,R More or less the same as a working directory: 2013/cur 1405500734.M958596P27867.host.domain.com,S=794,W=819:2,RS I've run # doveadm force-resync -u user .archives.2014 and nothing changed. I'm at a bit of a loss since no client can read them, something like moving them to another folder and back is a little complicated. Any hints?
