[Dovecot] Dovecot fails to deliver in mail clients
by Zwelabantu Ngwenya 12 Jun '09

12 Jun '09

Morning I am new to linux and have configured a Postfix + Dovecot Mail server on my SUSE Linux Server 10 SP2 Machine. Postfix works fine I assume as mail gets delivered to user's mailbox or directories. But when I configure a mail client to download mail from the server it finds no mail. When I check the user's mailbox using Webmin mail is delivered. I have also tried to telnet to the server when I do I am able to log in with user's credentials but when I type the list or stat command telnet says there is no mail 0.0Kb. I have tried everything, mail gets delivered to inboxes but telnet and mail clients don't get mail. Please let me know what I am doing wrong Zwelabantu Ngwenya

[Dovecot] unable to send mails via postfix/dovecot SASL
by Michal Szymanski 11 Jun '09

11 Jun '09

Hello, I have a freshly setup postfix/dovecot mail server (after a server upgrade I decided to change my sendmail/popper conf to something more modern :) It mostly works, there is no problem in sending/receiving mails in local network, both using text clients like mutt or pine dealing with the incoming/outcoming mail directly. Also dovecot works fine with SSL authentication from the outside world (home computers etc) but only for reading the mail. I have been struggling for several days already to get postfix/dovecot/SSL trio to work for sending (relaying) mail from the home computers (but also from local network) via my server to the final recipients, using authenticated connections. I followed http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL hints for the configuration of postfix and dovecot (see output of dovecot -n and postconf -n commands below). I also uncommented "smtps" line in /etc/postfix/master.cf file (otherwise postfix was refusing any connections to secure SMTP port). For a while, I uncommented also "submission" line there but to no success either. Now when I try to send a mail from my home PC, using Thuinderbird 2.0.0.21, with SSL connection configured for outgoing smtp server (port 465), using username/password, it shows "Connected to server..." message but after a minute or so, it fails saying that the connection to SMTP server failed. The server log shows: 11:51:24 sirius postfix/smtpd[15126]: connect from my_home_pc_name/ip Jun 11 11:52:25 sirius postfix/smtpd[15126]: lost connection after UNKNOWN from from my_home_pc_name/ip Jun 11 11:52:25 sirius postfix/smtpd[15126]: disconnect from my_home_pc_name/ip There are no dovecot-related messages in the log regarding such an attempt. I am not sure whether this is dovecot or postfix problem but, being no expert on either of those, I am asking help to resolve this annoying problem. with best regards, Michal. -------------- dovecon -n -------------------------- # 1.0.7: /etc/dovecot.conf ssl_cert_file: /etc/pki/dovecot/certs/sirius.pem ssl_key_file: /etc/pki/dovecot/private/sirius.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~/Mail:INBOX=/var/spool/mail/%u mmap_disable: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): outlook-idle pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login verbose: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix ----------------- postconf -n ---------------------------- alias_database = hash:/etc/mail/aliases alias_maps = hash:/etc/mail/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 header_checks = regexp:/etc/postfix/header_checks html_directory = no inet_interfaces = all mail_owner = postfix mailbox_command = /usr/bin/procmail mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man masquerade_domains = astrouw.edu.pl mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, mail.$mydomain, www.$mydomain, ftp.$mydomain, /etc/mail/local-host-names myhostname = sirius.astrouw.edu.pl newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_generic_maps = hash:/etc/postfix/generic smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/access, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_unlisted_recipient smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot unknown_local_recipient_reject_code = 550 --------------------------------------------------------------- -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Quota over NFS with inode limit
by Patrick Domack 11 Jun '09

11 Jun '09

I tried searching this list, but couldn't find anything related to inode limits except for linux quotas. I wanted to add sieve support for our users, so was attempting to get our email system to use dovecot's deliver lda to handle email, instead of postfix's virtual lda, using maildir mailstore. When I did this, I noticed that emails would get stuck in the queue if a user was over quota, this got fixed when I added in quota support, and set it up to check it using the line: quota = fs:User quota:user:inode_per_mail Now if a user excedes disk space via quota, it's bounced with a message. But if a user excedes their inode quota, it's still tempfail and hangs in the queue till it expires. I just wanted to know if anyone knows about this issue, if I made a stupid mistake or anything else, before I go digging into the source.

[Dovecot] record points outside file error with dovecot revision 9116:9ae55b68cf61
by Jonathan Siegle 11 Jun '09

11 Jun '09

I use mbox with mbox-snarf plugin. I get errors like: dovecot: IMAP(testuser): Corrupted index cache file /full/path/ dovecot.index.cache: record points outside file The errors can be in either folders or INBOX. I put some syslog statements in src/lib-index/mail-cache-lookup.c to help understand this. if (offset + sizeof(*rec) > cache->mmap_length) { mail_cache_set_corrupted(cache, "record points outside file"); syslog(LOG_DEBUG,"mail_cache_get_record rec->size is %d ", rec->size); syslog(LOG_DEBUG,"cache->mmap_length is %d ", cache- >mmap_length); syslog(LOG_DEBUG,"offset is %d ", offset); return -1; } syslog: mail_cache_get_record rec->size is 268595472 syslog: cache->mmap_length is 4096 syslog: offset is 1630760037 Oh I forgot to print off sizeof(*rec). Would that help? Thanks, Jonathan

[Dovecot] SELinux
by Kenneth Porter 11 Jun '09

11 Jun '09

I've temporarily got SELinux set to permissive mode on a fresh install on CentOS 5. It was blocking Dovecot's access to ~/mail because the files were labeled file_t. What's the correct way to label these?
