[Dovecot] Use both SQL and LDAP
by Shayne Jellesma 29 Jun '10

29 Jun '10

Hey guys, I am just wondering if it is possible to use both SQL and LDAP queries at the same time to get information. Example on why I want to do this: I work at a school where we have the need for 2 separate types of mailbox configuration (better wording is eluding me at the moment). Staff and Students currently share the same email server. I would like to be able to give staff a bigger inbox (eg: 500MB) than students (eg: 50MB). The way I am thinking, if this is even possible, to pull username and group membership from Active Directory. Check the groups against a SQL query to give the user the appropriate mailbox size. Also, having email is a privilege, not a right at my school so is it also possible to check if a user is part of a BannedEmailUsers or AllowedEmailUser group so I could quickly and effectively disable accounts as needed. I apologise if this is a little hard to follow. Writing what I want has never been a strongpoint for me J I also apologise if this has been asked, or information is available somewhere. I did search and didn't come up with much. Regards, Shayne Jellesma Network Administrator / ICT Support St Martins Lutheran College

[Dovecot] %d/%n doesn't work... why?
by William Ottley 29 Jun '10

29 Jun '10

Hello all, I've been trying to setup my postfix and dovecot to AUTH with mysql, and I'm almost there! BUT, for some reason, dovecot won't create the folders in their proper location. For some reason, instead of going into /var/vmail/pplsnet.com/{username}location, where the postfix put all the emails, dovecot creates a whole new set of folders in /var/vmail/{username} I have attempted to force dovecot to put into a sub directly, without using the %d, but that doesn't work either: #mail_location = mbox:/var/vmail/%d/%n mail_location = mbox:/var/vmail/pplsnet.com/%n Where do I look to figure out why its not putting it into the %d/%n location? does it have to do with the fact that AUTH graps the username, and NOT the domain name? (via mysql)? I have included dovecot -n and postconf -n.. can anyone take a quick guess and figure out what I should be doing? thanks! *dovecot -n* # 1.0.7: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login first_valid_uid: 150 last_valid_uid: 150 mail_extra_groups: mail mail_access_groups: mail mail_location: mbox:/var/vmail/pplsnet.com/%n maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 auth default: mechanisms: plain login digest-md5 cram-md5 passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail *postconf -n: *alias_database = hash:/etc/postfix/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 disable_vrfy_command = no html_directory = no inet_interfaces = all mail_owner = postfix mail_spool_directory = /var/spool/mail mailbox_size_limit = 500000 mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man message_size_limit = 10000 mydomain = rnd myhostname = mail.pplsnet.com mynetworks = 174.xx.xx.0/24 myorigin = $myhostname newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.2.10/README_FILES recipient_delimiter = + relayhost = sample_directory = /usr/share/doc/postfix-2.2.10/samples sendmail_path = /usr/sbin/sendmail setgid_group = postdrop smtp_tls_note_starttls_offer = yes smtp_use_tls = yes smtpd_banner = $myhostname smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_tls_CAfile = /etc/postfix/gd_bundle.crt smtpd_tls_cert_file = /etc/postfix/pplsnet.com.crt smtpd_tls_key_file = /etc/postfix/www.pplsnet.com.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = no smtpd_tls_session_cache_timeout = 3600s smtpd_use_tls = yes tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 450 virtual_alias_maps = mysql:$config_directory/mysql_virtual_alias_maps.cf virtual_gid_maps = static:12 virtual_mailbox_base = /var/vmail virtual_mailbox_domains = mysql:$config_directory/ mysql_virtual_domains_maps.cf virtual_mailbox_maps = mysql:$config_directory/mysql_virtual_mailbox_maps.cf virtual_minimum_uid = 150 virtual_uid_maps = static:150 * *

[Dovecot] Dovecot-2.0 conf misc questions
by Thomas Hummel 29 Jun '10

29 Jun '10

Hello, I'm setting up a dovecot-2.0.beta6 install and I'm experiencing the following issues/questions : 1. Converting the config file # /usr/local/dovecot-2/bin/doveconf -n -c /usr/local/dovecot-1.2.12/etc/dovecot.conf : [...] doveconf: Fatal: Error in configuration file /usr/local/dovecot-1.2.12/etc/dovecot.conf line 176: Unknown setting: process_limit but # grep -i process_limit /usr/local/dovecot-1.2.12/etc/dovecot.conf # Well, it doesn't bother me much since I made the dovecot-2 conf from scratch anyway. 2. Changing the process limit In 10-master.conf, I changed 'service imap''s 'process_limit' from 1024 to 4096 which caused : Warning: service auth { client_limit=4096 } is lower than required under max. load (5320) Where does the 5320 come from ? 3. The = <file syntax Is there anything to know about this new syntax other than files are introduced by "<" ? 4. The "filter" hierarchy My understanding is that protocol, remote, local must be specified in the following order protocol name { remote <ip|name> { local <ip|name> { and that for a match in several blocks, the more specific wins. but it's not clear to me where they are valid and if we can negate (with a ! for instance) an argument. For instance, I want to implement the typical case of "let clients from the inside network perform a plain auth over a clear connection, require SSL before auth for the outside network clients". For that, I want to put remote <internal network address> { disable_plaintext_auth = no } in 10-auth.conf and let the 'disable_plaintext_auth = yes' in dovecot.conf But : . why is this default not in 10-auth.conf file ? . would I have been allowed to do, for instance, in that file at the same line protocol imap { remote <internal network address> { disable_plaintext_auth = no } ? . would I have been allowed to do, for instance, in that file at the same line protocol ! imap ... or remote ! <some address> ? Besides, if I set ssl=required, do I still need disable_plaintext_auth = yes ? 4. auth unix listner Default is the unix socket 'auth-userdb'. Which processes communicate through this one ? Does that mean the the auth process is not the process which performs the actual passdb/userdb lookup ? In that case what is the 'userdb process' ? Same question : what is the auth-client socket used for ? Finally, would it make sense to declare other auth listeners than the two listed by default in the 10-master.conf file ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Dovecot dies, maybe ntpdate related. I'm new to dovecot
by Xavi Montero 28 Jun '10

28 Jun '10

Hi all, my first post. After years with an old server, a couple of months ago I've installed a new one. We use IMAP. After research, I chosed dovecot. It has been running for several weeks but from one week ago or so, it suddently dies about once per day. The only change done in the server one week ago has been to install ntpdate, running once per day in cron-daily. In the cron reports, ntpdate reports a time-jump of 9 seconds each night. We did this because "apparently" we did not a "soft time drift" installing the full ntp daemon, but I start thinking the time-jump crashes dovecot. QUESTIONS: - Might this time-jump cause dovecot to die? - I don't know wehere the dovecot logs are written to. Where do I start searching? Thanks to all!
