Pacaging/build issues with AIX and vac (dovecot-2.2.25)
by Michael Felt 10 Jun '17

Hi. I finally decided it was really time to stop being lazy and really move away from gmail. After I have a server in my basement using power, etc. So I turned on the imap provided - and did not quite cry - it will have to do for now, but imap2 is wanting. A real server yes, but not Linux. (Using linux would require another server AND I would feel I am being lazy again). So, I downloaded dovecot-2.2.25 and tried to build. Configure (messages to stderr) xlc is /usr/vacpp/bin/xlc + CPPFLAGS="-I/opt/include -I/opt/buildaix/include" CFLAGS="-I/opt/include -O2 -qmaxmem=-1 -qarch=pwr5 -I/opt/buildaix/includes ./configure\ --prefix=/opt \ --sysconfdir=/var/dovecot/etc\ --sharedstatedir=/var/dovecot/com\ --localstatedir=/var/dovecot\ --mandir=/usr/share/man\ --infodir=/opt/share/info/dovecot \ > .buildaix/configure.out xlc_r: 1501-216 (W) command option -dM is not recognized - passed to ld xlc_r: 1501-228 (W) input file c not found 1506-297 (S) Unable to open input file null.

v2.2.30.1 released
by Timo Sirainen 09 Jun '17

09 Jun '17

https://dovecot.org/releases/2.2/dovecot-2.2.30.1.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.30.1.tar.gz.sig Due to some release process changes I didn't notice that one important bugfix wasn't included in the v2.2.30 release branch before I made the release. So fixing it here with v2.2.30.1. Also included another less important fix. - quota_warning scripts weren't working in v2.2.30 - vpopmail still wasn't compiling Also I guess should mention that in v2.2.30+ the "script" service's protocol changed to a new version. If anyone had written their own script services (not using the included "script" binary) they would need some changes. I haven't heard of anyone having done that though.

[Dovecot] Dovecot stops with "Fatal: kevent(): Invalid argument"

# 2.0.11: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-STABLE amd64 Dovecot stops with the following logged: - master: Fatal: kevent(): Invalid argument I have found that a diff was created for "src/lib/ioloop-kqueue.c" for a similar issue: http://dovecot.org/pipermail/dovecot/2010-November/054855.html I have patched my system with this and haven't seen the problem since, but I don't know if this is a coincidence. Could you please explain if the diff should actually fix anything or just add some more logging in case it stops again? Best regards Henrik Larsson

Dovecot LDAP using custom field to allow users to connect
by Michael JOIGNY 09 Jun '17

09 Jun '17

Hi all, I'd like to know if it's possible to add a custom field when the authentification is made by users. My boolean custom field will be for example "AllowUser" (false/true). I'm trying to do something like that but it's not working : /user_filter = (&(objectClass=posixAccount)(uid=%u)(objectClass=myclass)(AllowUser=TRUE))/ This is my dovecot/ldap configuration below : /*# dovecot.conf* / /passdb {// // driver = ldap// // args = /etc/dovecot/dovecot-ldap.conf// //}/ *# dovecot-ldap.conf* /hosts = myurl:myport// //dn = cn=myuser,dc=mydomain,dc=com// //dnpass = ********// //a//uth_bind = yes// //auth_bind_userdn = uid=%u,ou=users,dc=mydomain,dc=com// //ldap_version = 3// //base = ou=Users,dc=mydomain,dc=com// //scope = base// //default_pass_scheme = SSHA512 / Do you have an idead ? Kind regards. -- Michael

lmtp: Error: Temp file creation to /tmp/ ... failed: No such file or directory on incoming mails with attachments
by Lars-Sören Steck 08 Jun '17

08 Jun '17

Dear list, I'm currently facing problems when receiving eMails with attachments, at least sometimes. My mailserver is set up with the tool 'Mailcow', and hence is based on Dovecot (2.2.22 (fe789d2)) and Postfix. Usually, there are no problems with receiving mails. If a mail has an attachment, however, it is possible that the following error occurs (extract from /var/log/mail.log): 'Jun 7 12:50:28 mail postfix/lmtp[26827]: 564E68A0515: to=<abc(a)def.ghj>, relay=my.mail.server[private/dovecot-lmtp], delay=0.71, delays=0.67/0.01/0.01/0.02, dsn=4.3.0, status=deferred (host my.mail.server[private/dovecot-lmtp] said: 451 4.3.0 Temporary internal failure (in reply to end of DATA command))' Extract from /var/log/mail.err: 'Jun 7 12:50:28 mail dovecot: lmtp(26828): Error: Temp file creation to /tmp/dovecot.lmtp.mail.26828. failed: No such file or directory' Once this happened the first time after dovecot is running, it will happen for all incoming mails with attachments. This can be solved temporarily by restarting the dovecot service and running postqueue -f, but that obviously does not solve the underlying problem. In this post to this list, it is stated that dovecot sometimes creates temp files to avoid 'excessive memory usage'. I'm guessing that this is the case here, also the error message is similiar: https://dovecot.org/list/dovecot/2016-June/104722.html Should I simply change the configuration variable mail_temp_dir to solve this? Why is dovecot not able to find the /tmp folder? In the list thread, it is stated that this is caused by dovecot running with enabled chrooting. As far as I understand it though (correct me if I'm wrong), chrooting is not enabled in my dovecot configuration. Please find attached the output of 'dovecot -n': # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-78-generic x86_64 Ubuntu 16.04.2 LTS auth_mechanisms = plain login dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf } listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c %k mail_home = /var/vmail/%d/%n mail_location = maildir:~/ mail_max_userip_connections = 500 mail_plugins = quota acl fts fts_solr 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 index ihave duplicate mime foreverypart extracttext namespace { list = yes location = maildir:%%h/:INDEXPVT=~/Shared/%%u prefix = Shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Archiv { special_use = \Archive } mailbox Archive { auto = subscribe special_use = \Archive } mailbox Archives { special_use = \Archive } mailbox "Deleted Messages" { special_use = \Trash } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Entwürfe { special_use = \Drafts } mailbox "Gelöschte Objekte" { special_use = \Trash } mailbox Gesendet { special_use = \Sent } mailbox "Gesendete Objekte" { special_use = \Sent } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Papierkorb { special_use = \Trash } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { acl = vfile acl_anyone = allow acl_shared_dict = file:/var/vmail/shared-mailboxes.db fts = solr fts_autoindex = yes fts_solr = url=http://127.0.0.1:8983/solr/ quota = dict:Userquota::proxy::sqlquota quota_rule2 = Trash:storage=+100%% sieve = /var/vmail/sieve/%u.sieve sieve_after = /var/vmail/sieve/global.sieve sieve_max_script_size = 1M sieve_quota_max_scripts = 0 sieve_quota_max_storage = 0 } protocols = imap sieve lmtp pop3 service auth { unix_listener /var/spool/postfix/private/auth_dovecot { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } unix_listener auth-userdb { mode = 0600 user = vmail } user = root } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 2 service_count = 1 vsz_limit = 128 M } service managesieve { process_limit = 256 } ssl_cert = </etc/ssl/mail/mail.crt ssl_cipher_list = EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH:+CAMELLIA256:+AES256:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!ECDSA:CAMELLIA256-SHA:AES256-SHA:CAMELLIA128-SHA:AES128-SHA ssl_dh_parameters_length = 2048 ssl_key = </etc/ssl/mail/mail.key ssl_protocols = !SSLv3 !SSLv2 userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota imap_acl acl fts fts_solr } protocol lmtp { auth_socket_path = /var/run/dovecot/auth-master mail_plugins = quota sieve acl fts fts_solr postmaster_address = postmaster(a)steck.cc } protocol sieve { managesieve_logout_format = bytes=%i/%o } remote 127.0.0.1 { disable_plaintext_auth = no } Thank you for your help.

mail storage auto detection failed?
by Alef Veld 08 Jun '17

Hi everyone. Nice to meet you. I’m new to dovecot and i came across a problem it seems. I setup a new user called sales with useradd, and gave it a password. Although it has a home directory, i set login to /sbin/nologin. When logging into the pop server on port 110 (with telnet) i get this in the logs: dovecot: pop3-login: Login: user=<sales>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=12938, secured, session=<94SotWVRoAB/AAAB> Jun 7 21:49:24 www dovecot: pop3(sales): Error: user sales: Initialization failed: Namespace '': Mail storage autodetection failed with home=/home/sales Jun 7 21:49:24 www dovecot: pop3(sales): Error: Invalid user settings. Refer to server log for more information. Did i have to initialise the mailbox in the homedirectory? What did i forget. I didn't change anything to the default dovecot.conf, i just installed the package with yum install dovecot (so latest version). This error also shows up when logging into port 143. Thanks for your help. My dovecot -n output if that helps is : [ec2-user@www log]$ dovecot -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 4.9.20-10.30.amzn1.x86_64 x86_64 mbox_write_locks = fcntl namespace inbox { inbox = yes location = prefix = } passdb { driver = pam } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem ssl_protocols = !SSLv2 !SSLv3 userdb { driver = passwd } Thanks a lot. -atv

Dovecot login is slow

Hi, I have an Ubuntu 16.04 server with dovecot 2.2.22 configured as an imap server with an LDAP backend for authentication. This is the output of "dovecot -n": # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-77-generic x86_64 Ubuntu 16.04.2 LTS auth_debug_passwords = yes mail_gid = vmail mail_location = maildir:~/ mail_privileged_group = mail mail_uid = vmail 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 } protocols = imap lmtp service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl_cert = </path/to/my/cert ssl_key = </path/to/my/key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext default_fields = home=/var/mail/vmail/%n driver = ldap } The problem i'm having is that when i try to login it takes more than 10 seconds, making my webmail very slow. For testing i login to imap like this "openssl s_client -connect localhost:993" and sometimes i get this message "* OK Waiting for authentication master process to respond..". I saw at other people, one of the problem was because they didn't disabled pam authentication when using another backend (like ldap or sql), but i already did that. Does anyone know what could cause such long login times and how to fix it?
