Re: Gnu sieve vs Dovecot sieve-filter - sieve-filter extremely slow at lda (writing emails to local mbox files)

(I did subscribe to this mailing list, albeit with zen at freedbms.net, so either way I'm getting all your emails - thank you -so- much for replying...) MUA is mutt, reading email in a terminal (sorry, forgot to mention this before). For many years now my email folder (mbox files) collection has grown to many GiB, mostly mailing lists. If I am to change email storage format, it should be mutt compatible; looking at https://wiki2.dovecot.org/MailboxFormat I see that only DJB's Maildir is compatible with both Dovecot ("a reliable choice" says the wiki), and mutt. I can imagine that sdbox or mdbox could be made "mutt compatible" so to speak, by running some sort of local IMAP server, and accessing my email from mutt that way; this is undesirable to my mind because this would require: 1) a new learning curve wrt mutt and reading email on IMAP servers 2) a new learning curve to set up a local IMAP server (securely) 3) the inability to use mutt without a local IMAP server to read my local email but such a setup would also have some quite desirable benefits: 1) once set up, multiple MUAs could be used, and I'd have a beginning grasp on setting up an IMAP server and front ends (this is something on my bucket list, to assist my local church with) 2) simpler remote "online" access to my local "offline" email store (e.g. using my mobile phone when on the road) by setting up a webmail server (much simpler (read "possible" to use on a mobile phone) than using a vpn and mutt...), thus freeing me up from the behemoth web email providers... Next, I do not know how to "pipe the messages to the dovecot lda". After downloading from my POP3 provider into a local mbox file (this is my step 1), then I sort the emails (this is my step 2): the following should be on a single line: /usr/bin/sieve-filter -veW -c $HOME/etc/email/sieve-dovecot-config.conf -o mail_location=mbox:~/mail:INBOX=~/mail/Inbox:INDEX=:UTF-8:VOLATILEDIR=/tmp/dovecot-volatile/%2.256Nu/%u:SUBSCRIPTIONS=dovecot_subscriptions ~/etc/email/sieve.rc email-incoming-unsorted As you can see from the above command, sieve-filter is given the name of the mbox ("mail folder") to sort, as its very last argument on the command line - so in this instance, sieve-filter really has no excuse, and should be not be re-reading the sieve rules script for each email - now perhaps that's not happening, I only made an assumption because of a CPU hitting 100% for a minute or two just to process a few 100 emails... What could also be happening (again, an assumption), is that sieve-filter is written to assume dovecot index files to be in existence. I disabled those with the "INDEX=" clause you see in the command above, which obviously has been given no value. The reason I figured out how to disable the creation of the indexes in the .imap directories, is that for my setup, Gnu sieve has proven that I should not need such indexes - with mbox files, just append each email to the end of the target "mailbox folder" mbox file, and we're done! This literally should not cost 100% CPU, even for one millisecond! But more importantly, because my working email folder is ~30GiB, without disabling this index creation step, sieve-filter forced the creation of indexes, which "took so long I gave up and hit CTRL-C, which did not work, so I kill -9'ed the sieve-filter and whatever other process was not stopping". Last year someone on debian-user recommended I upgrade to using Dovecot/Pigeonhole's sieve-filter (rather than Gnu sieve) due to the issues with Gnu sieve. I am starting to think that I should perhaps try to figure out if it's possible to (re)process the emails Gnu sieve has a problem with, to massage them into a shape that Gnu sieve accepts - then my immediate problem would certainly be solved... Thank you all again.. Zenaan

Case sensitive problem for vacation with dovecot lmtp pigeonhole
by kadafax＠gmail.com 11 Sep '19

11 Sep '19

Hi list, This issue was raised here by John Fawcett on 12/02/19 but got no response. So, as I'm facing the same issue, I would like to try again: When using the vacation sieve extension, if I send an email to user.name(a)mydomain.com it will work, but not to User.Name(a)mydomain.com. Is there a way to make the user part case insensitive so that the vacation auto-reply is fired whatever the way user part is written ? doveconf -n output: # 2.3.5.1 (7ec6d0ade): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.5.5 (2483b085) # OS: Linux 3.10.0-957.5.1.el7.x86_64 x86_64 CentOS Linux release 7.6.1810 (Core) ext4 # Hostname: myserver.mydomain.com auth_master_user_separator = * auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@* auth_verbose = yes debug_log_path = /var/log/dovecot-debug.log default_client_limit = 10640 default_process_limit = 2128 default_vsz_limit = 0 hostname = mydomain.com info_log_path = /var/log/dovecot.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * log_path = /var/log/dovecot-error.log login_greeting = Welcome mail_gid = vmail mail_location = maildir:/var/vmail/%Ln mail_plugins = quota fts fts_lucene mail_uid = vmail 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 inbox { inbox = yes location = maildir:/var/vmail/%Ln mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = type = private } passdb { args = /usr/local/etc/dovecot/deny-users deny = yes driver = passwd-file } passdb { args = /usr/local/etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { fts = lucene fts_autoindex = yes fts_lucene = whitespace_chars=@. quota = maildir:User quota quota_rule = *:storage=30GB quota_rule2 = Trash:storage=+200M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = /var/sieve-scripts/%Ln.sieve sieve_dir = /var/vmail/%Ln/home/sieve } postmaster_address = postmaster(a)mydomain.com protocols = imap pop3 lmtp sieve sieve quota_full_tempfail = yes service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0777 user = vmail } } service imap-login { inet_listener imaps { port = 993 ssl = yes } process_min_avail = 10 } service imap { process_limit = 2128 } service lmtp { executable = lmtp -L process_min_avail = 15 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = nobody } ssl_cert = </etc/letsencrypt/live/myserver.mydomain.com/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /usr/local/etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap override_fields = uid=vmail gid=vmail home=/var/vmail/%Ln/home } protocol imap { mail_max_userip_connections = 30 mail_plugins = quota fts fts_lucene imap_quota } protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log log_path = /var/log/dovecot-lmtp-errors.log mail_plugins = quota fts fts_lucene sieve } protocol sieve { mail_max_userip_connections = 20 }

Quota and maildir does not work with subfolders of INBOX
by Niels Kobschätzki 11 Sep '19

11 Sep '19

Hi, we just upgraded on FreeBSD (11.2-p14) from Dovecot 2.2 to Dovecot 2.3.7.2 and now we have kind of a big problem: the quota-plugin does not work correctly anymore. If a user has a subfolder of the INBOX (like .INBOX.foobar) the quota-calculation does not work anymore. It seems to be arbitrary but users get counted like double and more than they actually have in mails (the number of mails is correct, but the size gets calculated wrongly). The moment I remove those folders, the size gets calculated correctly. Unfortunately those folders are generated by some clients automatically afaik (like .INBOX.Trash) What can we do about that? There were already messages to the list about this in July 2018 but I didn't find any solution https://dovecot.org/pipermail/dovecot/2018-July/112439.html https://dovecot.org/pipermail/dovecot/2018-July/112440.html Niels

Off-site cloud backup (eg Amazon S3, Wasabi)
by James Brown 11 Sep '19

11 Sep '19

I’d like to synchronise our mail store to an Amazon S3 bucket or similar, for protection from ransomware. Server is running on macOS with maildir. Should I use a Dovecot process, rsync, a Mac app like Arq or Jungle Disk, or something else? Anyone have experience or opinions on this? Thanks, James.

Random duplicated emails
by Francis 11 Sep '19

11 Sep '19

Hello, I migrated our mail infrastructure to Dovecot on Ubuntu 18.04 some months ago. It works fine, but recently some users told me that they sometime receive duplicated emails. Same email content, same headers including message-id. I'm using two dovecot servers on two sites. Both server are in cluster. We don't use shared folders. All users that reported this issue so far are using the same server instance. The problematic emails are coming from local users on that instance too. The examples they given to me was emails with many recipients (To/CC). A specific message can be received twice (or more) by recipient A but only once by recipient B. I didn't see anything in the logs about sieve rules that redirect emails to others recipients. Where should I look to diagnostic this issue? Thanks.

Dovecot Director upgrade from 2.2 to 2.3
by Alessio Cecchi 10 Sep '19

10 Sep '19

Hi, I have a setup with 3 Dovecot Director v2.2.36 and director_consistent_hashing = yes ;-) Now I would like to upgrade to 2.3.7, first only Director and after also Backend. Can works fine a ring of director with mixed 2.2 and 2.3 version? Mi idea is to setup a new Director server with 2.3, stop one server with 2.2 and insert the new 2.3 in the current ring to check if works fine. If all works fine I will replace all Director 2.2 with 2.3 version. Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

dovecot duplicate emails

Hello. I have problems with duplicate emails when using replication and configured message filters on the client. Looks like when letter comes, it processed by replication and immediately after this processed by filter on client and moved to another folder. When it arrives to slave server into INBOX, it replicated back to master into INBOX and only after that - slave receives MOVE command.

New to dovecot admin, question about testing a dovecot configuration
by Gerben Wierda 10 Sep '19

10 Sep '19

I am new to dovecot administration, not new to postfix administration. When setting up a new postfix/dovecot combo from scratch, can I start with dovecot alone and still be able to test it? E.g. can I address the local delivery agent with some sort of test email? If so, how? I haven’t been able to find it in the wiki.

Force dovecot-uidlist reset
by Tom Sommer 09 Sep '19

09 Sep '19

Is there a way to force Dovecot to rebuild dovecot-uidlist from zero? It seems deleting all indexes and dovecot-* files followed by "doveadm force-resync" is not enough? It just gets the same UIDs? Perhaps from Maildir filenames? But I would like to reset the uid of all mails. Thanks -- Tom
