Sieve doesn't work after LTMP Director implementation
by Gonzalo Palacios Goicolea 12 Apr '21

12 Apr '21

Hi All, We're running dovecot director por proxying imap/pop queries to the backends. Yesterday we add LMTP proxying and it works fine, but we have realized that Sieve filters are no longer working after this change. Is it mandatory to add some config to the directors or backends after implementing LMTP through Director? We use dovecot-pigeonhole-2.2.36-8.el7.x86_64 dovecot-2.2.36-8.el7.x86_64 This is director servers config, if you also need backends config, please let me know doveconf -n # 2.2.36 (1f10bfa63): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.24 (124e06aa) # OS: Linux 3.10.0-1160.15.2.el7.x86_64 x86_64 Red Hat Enterprise Linux Server release 7.9 (Maipo) # Hostname: hidden auth_cache_negative_ttl = 5 mins auth_cache_size = 64 M auth_cache_ttl = 5 mins auth_failure_delay = 5 secs auth_verbose = yes default_client_limit = 40000 default_process_limit = 5500 director_mail_servers = Hidden director_servers = Hidden disable_plaintext_auth = no doveadm_port = 24245 listen = * lmtp_proxy = yes mail_location = maildir:%h/Maildir 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 mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = proxy=y nopassword=y driver = static } plugin { mail_log_events = delete undelete expunge mailbox_delete mailbox_rename mailbox_create save mail_log_fields = uid box msgid from subject sieve = file:~/sieve;active=~/.dovecot.sieve } service director { fifo_listener login/proxy-notify { mode = 0666 user = $default_login_user } inet_listener { port = 9090 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service doveadm { inet_listener { port = 24245 } } service imap-login { executable = imap-login director } service ipc { unix_listener ipc { user = dovecot } } service lmtp { inet_listener lmtp { address = x.x.x.x port = 24 } } service managesieve-login { executable = managesieve-login director } service pop3-login { executable = pop3-login director } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = # hidden, use -P to show it syslog_facility = local1 protocol lmtp { auth_socket_path = director-userdb } protocol doveadm { auth_socket_path = director-userdb } local 10.10.10.0/24 { doveadm_password = # hidden, use -P to show it } Thanks in advance and best regards -- *Gonzalo Palacios Goicolea* U.T de Infraestructura de Equipos Centrales /Tecnologías de la Información/ Universidad Autónoma de Madrid • Campus de Cantoblanco Antes de imprimir este correo piense si es necesario.Cuidemos el medioambiente.

Letsencrypt/OpenSSL test - Verify return code: 21
by B Shea 11 Apr '21

11 Apr '21

OS: Ubuntu 20.04.2 (on mutli-core VM) Dovecot (Ubuntu default/repo version): 2.3.7.2 (3c910f64b) OpenSSL (Ubuntu default/repo version): 1.1.1f 31 Mar 2020 Reproducing- Run: "openssl s_client -showcerts -connect imap.example.com:993 -servername imap.example.com" (using a diff domain obviously) Produces error: "Verify return code: 21 (unable to verify the first certificate)" (Meaning it is missing a CA verify from what I understand?) The "Verify return code: 21" error ONLY came to my attention after I had a customer complain about adding an email account to an Android phone (using the Google/Gmail default email app). -> "Certificate cannot be trusted" was shown by app when verifying imap connection. I could force it to be used, but this still bothered me, obviously. *The same certificate bundle is also used by smtp/postifx and www/nginx and works just fine. Also the openssl test shows 'verified' on both* I am posting to list mainly because on an older version of Dovecot I have running (default repo version for Ubuntu 18), I do not have this problem shown during testing with openssl. I did not have to change the ssl_cert or ssl_ca value in config. It has identical local.conf settings other than that. Granted it is also an older openssl version, too. So, I feel this may be a bug with Dovecot (or possibly OpenSSL). I finally 'fixed' it myself by using the LE 'fullchain.pem' certificate as the location for the 'ssl_cert' entry (and chain.pem for the ca entry). Previously, it was using the normal cert.pem file location. This is still the way it's setup on the other older machine and still works fine. Changes- |ssl_ca = </etc/letsencrypt/live/{CertName}/chain.pem (or 'fullchain.pem' should work) *ssl_cert = </etc/letsencrypt/live/{CertName}/fullchain.pem* (was 'cert.pem' previously) ssl_key = </etc/letsencrypt/live/{CertName}/privkey.pem| You can also view the problem here for more info : https://superuser.com/a/1640778/47628 Thanks ahead for any insight into this..

Debug: SSL_get_servername() failed
by Rowan ＠ Jetboy 10 Apr '21

10 Apr '21

I've setup Postfix to Dovecot LMTP delivery with mandatory TLS. Emails are being delivered with TLSv1.3 with no errors. However, setting: verbose_ssl = yes exposes this on each connection: lmtp(405619): Debug: SSL_get_servername() failed What it this mean, and what should I do about it?

debug SMTP commands sent/received to/from the submission service
by Victor Sudakov 09 Apr '21

09 Apr '21

Dear Colleagues, I'm trying to debug SMTP commands clients send to the submission service. I've tried protocol submission { rawlog_dir = /var/tmp/dovecot } but /var/tmp/dovecot remains empty. What am I missing? I'd use Wireshark but the communication between SMTP clients and Dovecot is encrypted after STARTTLS, so Wireshark is pretty useless here. Can you please point me to the right direction to log all SMTP commands? All is happening on Debian/buster, Dovecot 2.3.4.1. -- Victor Sudakov VAS4-RIPE http://vas.tomsk.ru/ 2:5005/49@fidonet

Incorrect value sent to solr
by Łukasz Szczepański 08 Apr '21

08 Apr '21

Hello, I've recently stumbled upon an error in fts-solr plugin. Dovecot sends "rows" parameter to solr when someone is searching in mailbox, but value of rows can be bigger than int in java. If I understand correctly, rows is equal to the last message id on current imap folder. I have mailbox where last uid value is 2206267083 and when I tried to search in this mailbox I got error 400 - Bad Request. On a Solr side I got an error: java.lang.NumberFormatException: For input string: "2206267083" NumberFormat expect an int which max value is 2147483647. Quick test reviles that rows parameter isn't required for correct response from solr. I think that dovecot should check if the value of rows is a correct int, and if not, just skip this argument. Dovecot version: 2.3.11.3 (502c39af9) Solr version: 8.7.0 ------------------ Łukasz Szczepański +48 58 3509284 www.webd.pl [1] Globtel Internet Links: ------ [1] http://www.webd.pl

imapsieve and master user
by André Rodier 07 Apr '21

07 Apr '21

Hello all, I have am imap sieve script, running fine. I would like to check, if it is possible, inside the sieve script, if the current user is a master user or not. I believe this is probably not possible. Otherwise, if it is not possible, I would like to check for an external condition, like an existing file in /tmp or in the mail dir folder, for instance. The issue is that I want my imap sieve script behave differently if the master user is connected. Thanks for any piece of advice. Kind regards, André Rodier

[Sieve] Understand Sieve processing

Hi, I have the following configuration: > cat > /etc/dovecot/conf.d/99-local-sieve.conf << EOF; > plugin { > sieve_before = /etc/dovecot/sieve-spam.sieve > sieve_before2 = /mail/sieve/global_before > sieve_after = /mail/sieve/global_after > sieve = /mail/sieve/%d/%n.sieve > sieve_dir = /mail/sieve/%d/%n > } > EOF > cat /etc/dovecot/sieve-spam.sieve > require ["regex", "fileinto", "imap4flags"]; > > if allof (header :regex "X-Spam-Status" "^Yes") { > fileinto "Spam"; > } (I removed the keyword "stop;" to proceed rule processing, which does not work) Now as a user (/mail/sieve/%d/%n.sieve) I want to create my own "Spam" rule: > require ["regex","reject"]; > # rule:[SPAM] > if allof (header :regex "x-spam-status" "^Yes") > { > reject text: > This E-Mail is SPAM. > . > ; > } I activate the traces and see the following if the e-mail is SPAM: > ## Started executing script 'sieve-spam' > 3: jump if result is false > 3: not jumping > 4: fileinto action > 4: store message in mailbox `Spam' > ## Finished executing script 'sieve-spam' If the e-mail is not SPAM: > ## Started executing script 'sieve-spam' > 3: jump if result is false > 3: jumping to line 4 > ## Finished executing script 'sieve-spam' > > > ## Started executing script 'roundcube' > 3: jump if result is false > 3: jumping to line 10 > ## Finished executing script 'roundcube' So my sieve gets only executed if the e-mail is not SPAM. Thats a bit odd. Could you explain how the sieve processing work and how I can solve this problem? dovecot --version 2.2.33.2 (d6601f4ec) on Ubuntu 18.04 LTS Best regards Homy

Things are working now. But I'm still baffled why basically the same master.cf config is working on one server but not another. I wonder if different SA configs might be the problem.

Sharing a single solr server between multiple dovecot servers
by Steve Dondley 06 Apr '21

06 Apr '21

I am brand new to solr and I'm interested in using sharing it between several dovecot machines I'm running. I'm looking for some big picture guidance on what I need to do to configure solr to work with the different dovecot machines. So far, I managed to set up a single "dovecot" core on the solr server and it is working with one of my dovecot machines. I'm not sure how to proceed from here as I'm very unclear on how solr maintains separate indexes for different users on my different machines. Some basic questions I have are: 1) Do I need a new core for each of the dovecot machines I want to use with solr? 2) If not, how does solr ensure indexes for the different dovecot user do not get comingled? 3) If yes, how do I configure dovecot to tell it which solr core to use? Thanks.

Avoid duplicate emails in the sent folder
by André Rodier 06 Apr '21

06 Apr '21

Hello, I have a webmail program, that I cannot configure to not save sent emails in the Sent folder. My emails to the SOGo team don't seem to reach the mailing list anymore. So, I have no other choice to think the problem differently, and _maybe_ use Dovecot to fix this issue. Moreover, I think this could be useful for other email clients. First, I have tried to use Sieve, but no success so far: ------ imapsieve_mailbox4_name = * imapsieve_mailbox4_from = Sent imapsieve_mailbox4_causes = APPEND, COPY imapsieve_mailbox4_after = file:/var/lib/dovecot/sieve/sent- checks.sieve ------ And this sieve script: ------ Message-ID header. require [ "variables", "environment", "duplicate", "imapsieve" ]; […] if duplicate :seconds 10 { discard; } ------ Otherwise, can I configure dovecot in a certain way, for instance create a virtual Sent folder. This would not save the email when appended, but still returns the list of sent emails ? But this is not working. Any idea? Thanks for your help! André

Emails to multiple recipients on same server not getting delivered
by Steve Dondley 05 Apr '21

05 Apr '21

When I send an email to a single user on a server, it is received by the user without a problem. But when sending to multiple users, the emails disappear into a black hole. The logs contain no errors and indicate the emails were sent: Apr 5 13:10:29 email postfix/pipe[31703]: F3A912027D: to=<pete2(a)example.org>, relay=spamassassin, delay=1.6, delays=0.12/0/0/1.5, dsn=2.0.0, status=sent (delivered via spamassassin service (X-Spam-Checker-Version: SpamAssassin 3.4.2 (2018-09-13) on email.example.org X-Spam-Level: X-Spam-Stat)) Apr 5 13:10:29 email postfix/pipe[31703]: F3A912027D: to=<pete3(a)example.org>, relay=spamassassin, delay=1.6, delays=0.12/0/0/1.5, dsn=2.0.0, status=sent (delivered via spamassassin service (X-Spam-Checker-Version: SpamAssassin 3.4.2 (2018-09-13) on email.example.org X-Spam-Level: X-Spam-Stat)) However, when I check the inboxes for the recipients, the email is nowhere to be found.

No decode2txt script for search attachments
by Steve Dondley 05 Apr '21

05 Apr '21

I'm looking at the documentation at https://doc.dovecot.org/settings/plugin/fts-plugin/#fts-decoder It says "See the decode2text.sh script included in Dovecot for how to use this." I don't have this script installed and can't find it anywhere on my Debian Buster server. I'm running dovecot version 2.3.4.1 Not sure if the documentation is outdated or what.

Search seems slow with apache solr
by Steve Dondley 05 Apr '21

05 Apr '21

I'm experimenting with Apache Solr and Dovecot. As far as I can tell, I have dovecot working with Apache Solr as demonstrated by this output: a search text "cash" * SEARCH 4 8 26 35 45 52 54 55 63 a OK Search completed (0.356 + 0.001 + 0.068 secs). However, when using the roundcube search bar and search all messages on a single word, it takes about 18 seconds. This seems slow as I only have about 4300 message in all my folders. But I'm not sure as I have nothing to compare it to. Is there a way I can test whether roundcube is using solr to perform searches?

Mass Stripping Attachments by Directory, Age, Size
by Plutocrat 05 Apr '21

05 Apr '21

Hi, I've been looking around for a solution to this problem. I want to prune down the attachments on a server before a migration. Some of the emails are 7 years old and have 40Mb attachments, so this seems like a good opportunity to rationalize things. So perhaps I'd like to "Remove all attachments from emails older than 2 years, in the .Sent directory", or "Attachments over 10Mb anywhere in the mail tree" I've found the strip_attachments.pl script here <https://fossies.org/linux/Mail-Box/examples/strip-attachments.pl> which works fine on mbox (as tested on my local Thunderbird mboxes), but not on maildir which is on the dovecot server. My Perl isn't strong enough to re-purpose it. I've looked at ripmime and mpack/munpack, and although they seem like useful tools to do the job of deconstructing the mail into its constituent parts, it doesn't seem to help in re-building the email. I think they could be used with a bit of study into mail MIME structure, and used with a helper script. So before I take a deep dive into scripting my own solution, I just wanted to check if anyone else on the list has been through this and has some resources or pointers they can share, or maybe even someone to tell me "Duh, you can do it with doveadm of course". P.

thunderbird copy old messages from other dirs
by Brian 05 Apr '21

05 Apr '21

Is there a known documented way to copy messages from backup folders into the cur folder and have them not make a mess of the dates. What I see is if I copy several year old messages to the cur folder on an ubuntu box the massages when viewed on an android phone appear out of order. I tried deleting the dovecot index and cache files and restarting the service, I also tried running these 2 scripts I found. I added some echoes to see what was occurring. Still, messages appear out of order and some do not appear at all on the droid. I tried copying the actual message files out of various cur dirs and still some were very out of date. The second script seemed to be adjusting the dates of the files properly, but I am not sure what android gmail actually uses to sort. #!/bin/bash for i in `ls /home/brian/Maildir/cur/` do # Find the date field and then remove up to the first space (Date: ) DATE=$(grep '^Date:' $i | head -1 | cut -d' ' -f1 --complement) # Create a timestamp from the date above STAMP=$(date --date="$DATE" +%Y%m%d%H%M) # touch the file with the correct timestamp touch -t $STAMP $i echo "$i stamped" echo "$DATE" echo "$STAMP" done ------------ #!/bin/bash # Fix emails with bad timestamps in a maildir # This script reads the date from the email header and set its UNIX timestamp and renames it with the proper date # e.g. this: # dec. 05 2017 1512499812.M908995P21566.ip-111-11-11-11,S=16331,W=16746:2,S # becomes that (the email Date header is "Date: Tue, 22 Oct 2013 10:07:21 +0100"): # oct. 22 2013 1382432841.M908995P21566.ip-111-11-11-11,S=16331,W=16746:2,S cd "/home/brian/Maildir/cur"; for i in `ls 1482809425.M277770P17438*` do echo "$i" # We extract the date from the email headers DATE=$(grep '^Date:' $i | head -1 | cut -d' ' -f1 --complement) # We compute a touch-compatible timestamp as well as the real timestamp TOUCHSTAMP=$(date --date="$DATE" +%Y%m%d%H%M) TIMESTAMP=$(date --date="$DATE" +%s) # We set the file timestamp touch -t $TOUCHSTAMP $i # We rename the file with preprending timestamp newfilename="$TIMESTAMP.${i#*.}" mv "$i" "$newfilename" echo "$newfilename" echo "******" done

.IMAP locations
by Elise 03 Apr '21

03 Apr '21

I have this account, /usr/home/me To be able to admin websites, I created a folder /usr/home/me/www , containing my siteroot /usr/home/me/www/mysite.com My dovecot.config: mail_location = mbox:/home/%u:INBOX=/var/mail/%u the actual mailfolder is /usr/home/me/mail , which I defined in my mailclient as 'mail/' The issue now is that Dovecot is indexing my whole /usr/home/me/ folder, including the www folder, in which it also idexes every folder that is in /usr/home/me/www/mysite.com . It puts in these folders an .imap folder that is containing the exact content of the folder it is put in. So my site takes double space by this Dovecot indexing. To solve this issue, I defined my mail_location line as mail_location = mbox:/home/%u/mail:INBOX=/var/mail/%u and removed the 'mail/' directive from my mail client. For some reason this does not prevent Dovecot to index the subfolders of /usr/home/me/www/ - Do I have to remove all Dovecot related indexing files by hand to solve this and restart Dovecot service afterwards? - Can you tell me how I can define the Dovecot index files location so that there will be no .imap folder created anymore in my /usr/home/me/www/ subfolder(s)? Thanks for you help! Elise #CSSis {beautiful};
