[Dovecot] Disallow POP3 from deleting messages
by DormitionSkete＠hotmail.com 23 Mar '13

23 Mar '13

I'd like to use Dovecot as our IMAP server when our users are within our LAN, but I'd also like to give them the ability to access their emails via POP3 when they are outside the LAN. I know most POP3 clients will give their users the option of not deleting the messages from the server after they are downloaded, but is there any way to restrict them from being able to do so at the server level? In other words, I want to disallow the server from accepting the DELE command from POP3 clients. Is that possible? We have some accounts that multiple users need simultaneous access to. I don't want a user to decide to set up a POP3 account on his own on his iPad or something, and inadvertently blow the Inbox away for everybody else. We have a satellite connection, so our upload speeds are real slow. I think POP3 would give a lot better user experience than IMAP when they are outside the LAN. Any help or advice will be greatly appreciated. Peter, hieromonk ---- Dormition Skete Monastery Website: http://www.DormitionSkete.org Convent Website: http://www.HolyApostlesConvent.org ----

Hint http://dovecot.org/list/dovecot/2012-December/069771.html does not seem to be valid for Dovecot 2.2 On the other hand I think it is not a suitable method to include CRLs into CA file. Certificate should include a link to CRL or - better - an URL to OCSP. Does Dovecot support OCSP? best regards Christian

[Dovecot] Altmove doesn't working after a dsync.
by Breno Moreira 22 Mar '13

22 Mar '13

Hi guys, I'm having a problem with the altmove command after a mailbox migration using dsync. What I'm trying to do is move some users from a datacenter to another and, for that, I'm using the dsync feature. First thing I do is run the dsync mirror command, and this is working properly, but all mails are moved to the main path, ignoring the ALT statement in the mail location. So, what I tried to do was run the doveadm altmove to move the old mails to the new alternate storage, but it simply doesn't work or sometimes moves only few messages. After the user receives new messages, these new files are correctly moved. It can be problem with my search parameter in the altmove command? Or this is a normal result? Best Regards, Breno Moreira -- --------------------------------------------------------------------- Breno Moreira

[Dovecot] How do I enable dsync sieve script replication?
by Oli Schacher 22 Mar '13

22 Mar '13

Hi all, Thank you Timo for adding sieve script replication to dsync, much appreciated! Should this run out of the box with 2.2.rc3 and latest pigeonhole+patch or does this have to be enabled in the configuration somehow? I upgraded my dsync replication test setup, but it doesn't sync sieve so far, so I'm not sure if this is a config issue or if I maybe made a mistake while upgrading/patching. btw: not sure if you saw this bugreport, dsync over tcp still produces "no command given" errors randomly (http://www.dovecot.org/list/dovecot/2013-March/088751.html) Thanks Oli #dovecot -n: # 2.2.rc3: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.22.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_master_user_separator = * auth_mechanisms = plain login dict { acl = mysql:/etc/dovecot/dovecot-dict-shares.conf quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf } disable_plaintext_auth = no doveadm_password = <munged> listen = * login_greeting = Dovecot ready. mail_max_userip_connections = 50 mail_plugins = " quota notify replication" 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 namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile:/etc/dovecot/acls acl_shared_dict = proxy::acl mail_replica = tcp:<munged>:1337 quota = dict:::proxy::quotadict quota_rule = *:storage=10M:messages=1000 quota_rule2 = Spam:ignore quota_rule3 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=75%% quota-warning 75 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = pop3 imap lmtp sieve service aggregator { fifo_listener replication-notify-fifo { user = fumail } unix_listener replication-notify { user = fumail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = fumail mode = 0660 user = fumail } user = root } service dict { unix_listener dict { mode = 0600 user = fumail } } service doveadm { inet_listener { port = 1337 } } service imap { vsz_limit = 2 G } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve { vsz_limit = 2 G } service pop3 { vsz_limit = 2 G } service quota-warning { executable = script /usr/local/bin/quotawarning.py unix_listener quota-warning { mode = 0666 user = fumail } user = fumail } service replicator { process_min_avail = 1 } ssl_cert = </etc/ssl/<munged>.crt ssl_key = </etc/ssl/<munged>.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = mail_plugins = " quota notify replication acl imap_acl quota imap_quota" } protocol pop3 { mail_plugins = " quota notify replication quota" pop3_uidl_format = %08Xu%08Xv } protocol sieve { managesieve_logout_format = bytes ( in=%i : out=%o ) } protocol lmtp { deliver_log_format = from=<%f> msgid=%m action=<%$> subject=%s mail_plugins = " quota notify replication sieve quota" postmaster_address = postmaster@<munged> quota_full_tempfail = yes } -- message transmitted on 100% recycled electrons

[Dovecot] v2.2 dsync_brain_lock() FLOCK compatibility issue on Solaris 11.1
by Walter Steiner 22 Mar '13

22 Mar '13

Hello, On Oracle Solaris 11.1 (Solaris gcc-45 package set) core libraries do not provide flock() anymore. in file: src/doveadm/dsync/dsync-brain.c in function: dsync_brain_lock() around line: 234 is a (maybe unintentional) fix reference to FLOCK locks. if (file_wait_lock(brain->lock_fd, brain->lock_path, F_WRLCK, FILE_LOCK_METHOD_FLOCK, brain->lock_timeout, &brain->lock) <= 0) { resulting in a runtime error about unsupported flock() locks. (HAVE_FLOCK is not set by configure script) Personally, I have just changed "FLOCK" to "FCNTL". [ I have tried brain->lock->lock_method but this seems not to be the correct way => compile time error: dereferencing pointer to incomplete type ] Walter

Re: [Dovecot] Problem with Prefetch User Database

I use PAM because of the easyness of blocking specific validated users - you can just add/remove them in a plain text file. Easy administration will be necessary because of the planned huge amount of users on the system (28.000), and sometimes blocking a user is highly time-dependent (e.g. if one answers to a phising mail and sending out his credentials which are then abused for sending spam). I would go over LDAP if there is an equivalent easy way to solve this over LDAP (easy blocking out users by e.g editing a plain text file) - is there any?

[Dovecot] 2.2.rc2: problem with acl_shared_dict
by Lutz Preßler 22 Mar '13

22 Mar '13

Hello, 2.2.rc2, configuration as before: acl_shared_dict=file:... The contents of this file is used for e.g. LISTing shared mailboxes. But even with file and directory beeing world writable, it's not written into on SETACL commands. Instead, at least sometimes (it seems to make a difference if GETACL is used before in the session) the imap process crashes on SETACL or DELETEACL. Feb 26 00:31:52 host dovecot: imap(13373, user) K64y8ZTWOgB/AAAB: Fatal: master: service(imap): child 13373 killed with signal 11 (core dumps disabled) Anything to do for further debugging? Working correctly with 2.1.15. Greetings, Lutz

[Dovecot] director's imap/pop3 login timeout
by Angel L. Mateo 21 Mar '13

21 Mar '13

Hello, We have two (load balanced) director servers in front of 4 dovecot backend servers. Yesterday we had a problem at backend servers for some users (our SSO was down, so IMAP users couldn't authenticate) and this triggered a problem in director servers where almost nobody could open a new session. In our director's logs I could see errors like this: Mar 20 20:52:47 myotis41 dovecot: imap-login: proxy(<user>): Login failed to 155.54.211.162:143: [UNAVAILABLE] Temporary authentication failure. [myotis32:2013-03-20 19:52:47] So, it seems it was trying to authenticate for 1 hour, after that it timed out the login. But this timeout is too long. Is this a director timeout? Or a backend timeout? How can I reduce it? -- Angel L.
