Sending emails using dovecot auth
by Murray Trainer 16 Jul '14

16 Jul '14

Hi All, I have noticed that dovecot / exim on Cpanels appear to support sending emails via exim after authenticating to Dovecot - see message below 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message We are migrating users mail off cpanels into split mta and dovecot servers and are having problems with some users being abble to send emails afterwards. Does anyone understand how the CPanel config works? Thanks Murray

ATrpms repo

Tried mailing the maintainer, but didn't get a response -- anyone know what's happened to the ATrpms repo? Not only is http://atrpms.net/name/dovecot/ empty, but: http://packages.atrpms.net/dist/el6/ seems to return a 404. Some of the mirrors still have the packages, but does anyone know if they're going to continue to build 2.2.x packages? w

fts solr database size

Hi, Could anyone share any numbers about real life solr database size/cpu/memory usage for certain amounts of messages ? We have now over 5TB of maildirs (about 5 000-6 000 concurrent imap clients) and I'm trying to guess how much hardware might be needed. -- Michal

Dovecot2 Antispam MAILTRAIN backend with SpamAssassin
by Mohammad S. Babaei 15 Jul '14

15 Jul '14

Hi there, I've already asked this question on FreeBSD forums without getting any response. So, I thought it's a good idea to ask it again here. I've setup Dovecote2 (2.2.13) + Postfix + SpamAssassin on my FreeBSD 10 VPS and it works flawlessly. Though, I couldn't setup the Dovecot Antispam plugin to train SpamAssassin when I move mails to the Junk folder. I installed the plugin from FreeBSD ports and followed the official documentation [1] and the man page [2] without any success. This is my configuration: ######## # 2.2.13: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.0-RELEASE-p6 i386 ufs auth_mechanisms = plain login digest-md5 disable_plaintext_auth = no first_valid_gid = 6 first_valid_uid = 26 last_valid_gid = 6 last_valid_uid = 26 lmtp_save_to_detail_mailbox = yes mail_gid = mail mail_location = mdbox:/mail/%d/%u mail_privileged_group = mail mail_uid = mailnull 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 namespace inbox { inbox = yes location = mailbox Archive { auto = no special_use = Archive } mailbox Drafts { auto = subscribe special_use = Drafts } mailbox Flagged { auto = no special_use = Flagged } mailbox Junk { auto = subscribe special_use = Junk } mailbox Sent { auto = subscribe special_use = Sent } mailbox Trash { auto = subscribe special_use = Trash } mailbox virtual/All { auto = no special_use = All } prefix = separator = / } passdb { args = /mail/%d/dovecot_passwd driver = passwd-file } plugin { antispam_backend = MAILTRAIN antispam_mail_notspam = --ham antispam_mail_sendmail = /mail/sa-learn-pipe.sh antispam_mail_spam = --spam antispam_spam = Junk antispam_trash = Trash quota_rule = *:storage=8GB sieve = /mail/%d/%u/dovecot.sieve sieve_dir = /mail/%d/%u sieve_global_dir = /mail/sieve sieve_global_path = /mail/sieve/globalfilter.sieve } protocols = imap pop3 lmtp sieve service auth { unix_listener auth-client { group = mail mode = 0660 user = postfix } unix_listener auth-master { group = mail mode = 0600 user = mailnull } user = root } service imap-login { inet_listener imap { address = * port = 143 } inet_listener imaps { address = * port = 993 } process_limit = 32 process_min_avail = 1 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } service managesieve { process_limit = 1024 } service pop3-login { inet_listener pop3 { address = * port = 110 } inet_listener pop3s { address = * port = 995 } process_limit = 32 process_min_avail = 1 } ssl_cert = </etc/ssl/dovecot/cert.pem ssl_key = </etc/ssl/dovecot/key.pem userdb { args = /mail/%d/dovecot_passwd driver = passwd-file } verbose_proctitle = yes protocol lmtp { mail_plugins = " sieve" postmaster_address = postmaster(a)SomeDomain.com quota_full_tempfail = yes } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_plugins = " quota imap_quota antispam" } protocol pop3 { mail_plugins = " quota" pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = " quota sieve" postmaster_address = postmaster(a)SomeDomain.com sendmail_path = /usr/local/sbin/sendmail } ######## And, this is the script /mail/sa-learn-pipe.sh: ######## echo /usr/local/bin/sa-learn $* /tmp/sendmail-msg-$$.txt echo "$$-start ($*)" >> /tmp/sa-learn-pipe.log #echo $* > /tmp/sendmail-parms.txt cat<&0 >> /tmp/sendmail-msg-$$.txt /usr/local/bin/sa-learn $* /tmp/sendmail-msg-$$.txt rm -f /tmp/sendmail-msg-$$.txt echo "$$-end" >> /tmp/sa-learn-pipe.log exit 0 ######## I made it excecutable by all users using chmod a+x /mail/sa-learn-pipe.sh The problem is, there is no log in /var/log/maillog regarding the Antispam plugin, and the script won't get called when I move any message in/out to/from Junk folder.

Permissions with mailman
by Niklas Lemcke - 林樂寬 15 Jul '14

15 Jul '14

Hi, I'm running a Mailserver, and recently also a Mailinglist. I'm sporting # dovecot --version 2.1.7 on a debian stable machine with postfix & mailman. Everything works fine, except that no archive is being created (here an excerpt from my log): Jul 2 15:29:39 blade01 postfix/qmgr[5217]: B30BCE1F52: from=<list(a)mail.myserver.com>, size=802, nrcpt=1 (queue active) Jul 2 15:29:39 blade01 dovecot: lda(list): Error: user list: Initialization failed: Initializing mail storage from mail_location setting failed: mkdir(/var/mail/vmail//list/mail) failed: Permission denied (euid=38(list) egid=38(list) missing +w perm: /var/mail/vmail/, we're not in group 5000(vmail), dir owned by 5000:5000 mode=0775) Jul 2 15:29:39 blade01 dovecot: lda(list): Fatal: Invalid user settings. Refer to server log for more information.

Now: $ groups list list : list vmail and the permissions are 775, but it's still complaining about "missing +w perm". What is it referring to with "we're not in group 5000"? Thanks for any help! -- Niklas - 林樂寬

All, Just move our mail servers over to a new mail server running postfix 2.11.1 and dovecot 2.2.13 and getting the subject line errors in my /var/adm/files. People are complaining of loosing their connections to the mail server. I've been able to google this error but haven't found fix for this yet. NOt sure where to put the drop-priv option in the config files either. Any suggestions?

Changed IMAP MOVE behavior in Dovecot 2.2.x
by Iavor Stoev 15 Jul '14

15 Jul '14

Hello, After the migration to Dovecot 2.2.13 from Dovecot 2.1.17, I noticed a changed behavior when I move a message from one folder to another. I use Thunderbird with: Account Settings -> Server Settings -> When I delete a message: Just mark it as deleted. I use Thunderbird 24.6.0 with IMAP. With Dovecot 2.1.x when I move a message, the message appears in the new folder and is marked for deletion in the original folder (which gives me an easy option to undo the action if I made a mistake until I choose to Compact/Purge the folder). With Dovecot 2.2.x when I move the a message it is marked for deletion and is AUTO Compacted/Purged immediately. Is there a way to achieve the 2.1.x behavior with Dovecot 2.2.x? Thank you Iavor

Integrity check of mailboxes before dsync
by Murray Trainer 15 Jul '14

15 Jul '14

Hi All, I am migrating a large number of Dovecot mailboxes - some of them are quite old. I hit an issue yesterday with a corrupt file (index?) that was preventing the mailbox from being synced properly As soon as I removed the file the dsync worked. Is there a way to check the integrity of each mailbox / indexes before I dsync it? Thanks Murray
