imapc settings for specific mailbox / namespaces
by Tobia Grosselle [ Terralink ] 17 Feb '21

17 Feb '21

Hello, Is it possible to use imapc for specific mailbox or namespace? Something like this: namespace Test { list = no type = private inbox = no hidden=no prefix = TEST/ separator = / location = imapc: imapc_host = imap.example.com imapc_password = secret imapc_port = 143 imapc_user = user(a)example.com } or is only intended for general use as general proxy in the global configuration?

Logfile flooding with lookup failure for root user using pam
by Michael Ruiz 16 Feb '21

16 Feb '21

Hi all, I am getting the error where root is constantly being lookedup over imap I am guessing. I am pretty sure services like fail2ban and logwatch are setup to send from another user instead of root @ localhost so I think this may be an imap issue. I tried adding root to /etc/dovecot/deny-users , but this error still persists. I know imap as root is a big security issue and is disabled, but I cannot pinpoint how or why this is happening so often. I am using PAM and passwd for authentication and authorization. How can I prevent root user from being looked up in the first place ? Regards, Michael dovecot[606167]: lmtp(606199): Error: lmtp-server: conn unix:pid=606196,uid=73 [2]: rcpt root@<domain>: Failed to lookup user root@<domain>: Invalid settings in userdb: userdb returned 0 as uid replaced my domain name with <domain> in this example.

quota_max_mail_size and dsync
by Edgaras Lukoševičius 15 Feb '21

15 Feb '21

Hello, as we have enabled quota_max_mail_size, dsync is now having problems moving oversized emails between servers. Is there a way to configure dovecot (dsync) to allow syncing of emails larger than quota_max_mail_size but keep limiting clients over imap/pop/lmtp? The error logged is: dsync(local(a)domain.tld): Info: imapc(remote.imap.host.tld): Connected to II.III.III.II:PPP (local II.III.III.II:PPPPP) dsync(local(a)domain.tld): Warning: Failed to copy source UID=24 mail: Mail size is larger than the maximum size allowed by server configuration - falling back to regular saving dsync(local(a)domain.tld): Error: Mailbox INBOX.Sent: Saving failed: Mail size is larger than the maximum size allowed by server configuration

Mail.app namespaces
by Dan Mahoney (Gushi) 15 Feb '21

15 Feb '21

All, Dovecot 2.3.13 under Freebsd 11.3, installed via pkg. I had a question related to dovecot and OSX mail.app. My primary mailer is "alpine". Sometimes I need to see a message in a graphical app so I occasionally turn to mail.app. I keep a lot of old mail. Mail.app on recent macos versions insist on downloading *everything* for easier searching and indexing. Most of which I don't need. (20G of mail over the last 20+ years, plus a bunch of mailing lists I keep archived, but only read when I need to search them). ios mail doesn't do this. Subscriptions don't work (in mail.app, subscriptions are only for public/shared folders). Ergo, is there a server-side way to make just one client not able to see/list/download ALL folders? Perhaps by presenting them as subscription folders, or perhaps by hiding them in the namespace. I'm not unwilling to configure an alternate namespace for myself. (It's helps that I'm the sysadmin here). Ideally, this would be a thing I could only set for my account -- match on a user-agent/username string of some sort? (My other option has been "create a different username and forward to myself there", but this feels like it should be solvable). -Dan My doveconf follows: # 2.3.13 (89f716dc2): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 11.4-RELEASE-p3 amd64 # Hostname: prime.gushi.org disable_plaintext_auth = no mail_full_filesystem_access = yes mail_location = mbox:%h/mail:INBOX=%h/.mail:INDEX=/var/db/indexes/%u namespace { alias_for = hidden = yes list = no location = prefix = mail/ separator = / } namespace { alias_for = hidden = no list = yes location = prefix = ~/mail/ separator = / subscriptions = yes } namespace { alias_for = hidden = yes list = no location = prefix = ~%u/mail/ separator = / } namespace { hidden = no list = yes location = mbox:~%u/.incoming/ prefix = Inbounds/ separator = / } namespace inbox { inbox = yes location = prefix = separator = / } passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } service imap-login { inet_listener imap { port = 143 } inet_listener imap_other { port = 1143 } inet_listener imaps { port = 993 ssl = yes } inet_listener imaps_other { port = 1993 ssl = yes } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3_other { port = 1110 } inet_listener pop3s { port = 995 ssl = yes } inet_listener pop3s_other { port = 1995 ssl = yes } } ssl_cert = </etc/mail/certs/prime.gushi.org.certkey ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC FB: fb.com/DanielMahoneyIV LI: linkedin.com/in/gushi Site: http://www.gushi.org ---------------------------

doveadm expunge logging
by Arkadiusz Miśkiewicz 11 Feb '21

Hello. dovecot 2.3.13 here, using doveadm -c /etc/my.conf expunge -A mailbox SomeFolder savedbefore 31d and my.conf includes plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename save } unfortunately expunged messages are not logged anywhere. Tried -v and -D to see if these will get logged to output (so I could pipe these to syslog) but verbose/debug also don't show which messages were expunged. Is there a way to get this logged?

Hi I'm made a lot of test trying to get SLQ auth driver work with vpopmail/mysql configured with many domains (one table for each domain) Finally I made it work, but ... only with PLAIN password Is there a way to make SQL auth work with vpopmail/mysql tables with encrypted password (CRAM-MD5 / MD5-CRYPT) ?

Re: SQL-AUTH driver replace for VPOPMAIL-AUTH

It seems like it would be possible to use a view table (with a union query) to "make" the many domain style table out of the tables by domain. You wouldn't want to do that if you were adding domains often... but it should make the dovecot auth for many domains work on top of the old tables instantly.Sent from my T-Mobile 4G LTE device------ Original message------From: Eric BrochDate: Wed, Feb 10, 2021 2:58 PMTo: dovecot(a)dovecot.org;Cc: Subject:Re: SQL-AUTH driver replace for VPOPMAIL-AUTHPablo, Can you share your dovecot-sql.conf.ext file for 'one table for each domain'.

Problem enabling the mail_log plugin
by Mike Quigley 09 Feb '21

I need to track some issues with deleted messages so I have been trying to set up the mail_log plugin. I have Dovecot v2..27 running on Debian 9. I have configured /etc/dovecot/conf.d/10-logging.conf, 20-imap.conf, and 20-lmtp.conf and restarted dovecot, but I see so difference in /var/log/mail.info & /var/log/syslog when I delete a message from my Inbox in Roundcube.

I'm unable to get Claws-Mail to work with SSL/993 with a passphrased selfsigned cert
by Steve Litt 06 Feb '21

06 Feb '21

Hi all, First, thanks to everyone on Freenode #dovecot who helped me with my extreme problems a couple days ago. I once again have Claws-Mail able to connect to my SSL/993 only Dovecot IMAP, after making my own cert and a few other things. Here's the deal though. When I try to use an rsa:4096 cert with a passphrase for dovecot, Claws-Mail cannot connect, even though I put the cert's passphrase in Claws-Mail's passphrase field right below the field for the cert's location/filename. It tells me it can't import the p12 cert. This happens whether I put in the location of the public cert, or the private one. What do I need to do to get Claws-Mail and Dovecot to work together with a passphrased cert? Naturally, this could be a deficency in Claws-Mail, and I've written a similar email to the Claws-Mail group, but either way I'd like to get this solved so I'm not using a no-password cert. By the way, when I do: openssl s_client -connect 192.168.0.2:993 \ -cert/etc/ssl/dovecot_certs/private/dovecot.pem openssl asks me for the passphrase and upon receiving it gives me the information. This does not happen if I give it the location of the public key. Thanks, SteveT Steve Litt Autumn 2020 featured book: Thriving in Tough Times http://www.troubleshooters.com/thrive

Service unavailable, lots of idle dovecot-login processes
by Wolfgang 05 Feb '21

05 Feb '21

Hi, Web search turned no results to this problem: We have a small site running private e-mail for maybe 12 people, dovecot is used by Postfix-SASL and IMAP clients. PROBLEM: When starting dovecot, after a few hours, IMAP clients are no longer able to connect. Thunderbird indicates that connection is refused. On the server, we see 100 dovecot/imap-login processes. This is the process limit. If we increase the process limit to 200, same thing, we survive a few hours longer but eventually we're seeing 200 imap-login processes and rejected connections. When listing TCP connections via lsof, there are only around 30 connections open to IMAP and we have exactly the same amount of dovecot/imap processes. These connections are held by 30 dovecot/imap-login processes. The other 70 dovecot/imap-login processes seem to do nothing. They're all sitting in "epoll_wait(14," according to strace but don't have TCP connections open. The only way out of this that we have found is re-starting dovecot every few hours. BTW, service_count = 1 for improved security. Dovecot Version: 2.3.4.1 (f79e8e7e4) Interestingly we were using nearly the same config on our old server with 2.2.13 and did not see this issue. Any ideas how to solve that properly? Thank you, Wolfgang

logging verbosity
by Fourhundred Thecat 05 Feb '21

05 Feb '21

Hello, I get lots of these messages in the log: dovecot: imap-login: Login: user(a)1.2.3.4, TLSv1.3 with .. dovecot: imap(user)<10889><glzsCIi6AMbUGQtL>: Disconnected for inactivity ... dovecot: imap(user)<10887><vzjQB4i6/MXUGQtL>: Logged out ... when user clicks on folder in Thunderbird, or sometimes even when the Thunderbird window is in focus (without clicking anything). Anyway, how can I suppress these info messages, while keeping the important ones, such as auth problems? I am using Dovecot v2.3.4.1 with 10-logging.conf with default values. I see there is this line: # Log unsuccessful authentication attempts and the reasons why they failed. auth_verbose = yes I definitely want to keep logging unsuccessful auth, but how can I suppress the verbose rest? and lastly, can these settings be set per-user? Can I suppress verbose for user 'bob' but keep for others? thanks,

Several users, same mailbox
by Adrian 04 Feb '21

04 Feb '21

Hello, I have had Dovecot set up to use PAM authentication, as my current users all have system accounts on Debian. I've just moved over to passwdfile authentication, because I want to add new users who won't have logins on the system. This is working fine with my existing users. Now, the problem is that I want the new users to share the SAME (Maildir) 'mailbox'. Currently 10-mail.conf contains mail_location = maildir:/var/mail/%u:LAYOUT=fs so this needs to be overridden, or I need some new way of mapping users to mail locations. I could probably do it with symlinks from /var/mail/newuser to /var/mail/mail-location but there may be a better way to do it than that. I'd like it to be in a file, not needing mySQL or other database. Lastly, are there any implications for locking? These will be used rarely but if a second user logs in for the same mailbox they should get a lock error. dovecot -n # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.19.0-11-amd64 x86_64 Debian 10.7 ext4 # Hostname: example.com disable_plaintext_auth = no mail_location = maildir:/var/mail/%u:LAYOUT=fs Thanks in advance

Restarting indexing?
by Philip Warner 04 Feb '21

04 Feb '21

Hi, I have about 80GB of mail to index using Dovecot 2.3.4.1 and xapian 1.4.11 FTS. After about 18 hours I had to reboot the server for an unrelated reason (it was perhaps a quarter of the way through indexing). After reboot, the indexing did not restart, and I could find no way to restart it other than via the ‘doveadm index’ command, which I have now done, with the result that the indexing has restarted from scratch. Is there a way to coax it to restart from where it left off, in case I need another reboot? Sent from Mail for Windows 10

Regards, Michael dovecot[106888]: lmtp(572901): Warning: Event 0x55ee2285bd30 leaked (parent=(nil)): lmtp-client.c:173: 1 Time(s) dovecot[106888]: lmtp(572901): Warning: Event 0x55ee228774e0 leaked (parent=0x55ee228772d0): mail-storage-service.c:1336: 1 Time(s) dovecot[106888]: lmtp(572901): Warning: Event 0x55ee22877ef0 leaked (parent=0x55ee228711c0): mail-storage-service.c:1336: 1 Time(s) dovecot[106888]: lmtp(572901): Warning: Event 0x55ee2287b3b0 leaked (parent=0x55ee22856e00): smtp-server-transaction.c:58: 1 Time(s) dovecot[106888]: lmtp(572901): Warning: Event 0x55ee2287d5f0 leaked (parent=0x55ee2287db10): smtp-server-recipient.c:38: 1 Time(s) dovecot[106888]: lmtp(572901): Warning: Event 0x55ee2287db10 leaked (parent=0x55ee22856e00): smtp-server-transaction.c:58: 1 Time(s) dovecot[106888]: lmtp(572901): Warning: Event 0x55ee22883700 leaked (parent=0x55ee228877e0): smtp-server-recipient.c:38: 1 Time(s) dovecot[106888]: lmtp(572901): Warning: Event 0x55ee22883910 leaked

Custom quota exeed message
by rudolf＠padaru.de 03 Feb '21

Hey there, i need some help with custom quota messages with dovecot and postfix. The quota setup is clear and easy, now i want to manipulate the exceed message, which is generated, if the mailbox is full. Now i got something like that Your message to <user(a)my.server.com> was automatically discarded: Quota exceeded (mailbox for user is full) The first line so i think is generated from postfix and cant be edit or? The second line is generatet from dovecot and i can manipulate there with the quota_exceeded_message variable. My problem is, that the sender cant see the mail-adress where he originally send the mail. Because the user is an local user on my server. I need somethin like that: Your message to <peter.schmidt(a)schmidt.com> was automatically discarded: Quota exceeded (mailbox for user is full) Is there an way to manipulate the first line of answer? Ori s there an way, that i can run a custom script in the quota_exceeded_message var? With the latter variant i would be able to create something like: Your message to <user(a)my.server.com> was automatically discarded: Quota exceeded (mailbox for user <peter.schmidt(a)schmidt.com> is full) But configurations like quota_exceeded_message = script /my/script.sh wont execute the script. Does anybody have an idea? Mit freundlichen Grüßen Yours sincerely Pascal Rudolf

how to dovecot import to folder/, not folder/INBOX
by didar 02 Feb '21

02 Feb '21

Hi, I am trying to import old Gmail mails from a maildir source into dovecot folder. chowm -R vmail:vmail /tmp/batch-1234 doveadm import -u gmail maildir:/tmp/batch-1234 2011 all This works, but it imports the emails into "2011/INBOX" rather just into "2011". Since, the "gmail" user account has maildir storage itself, I rename the "%h/.2011.INBOX" to "%h/.2011" manually and it seems to be working. I am wondering if there is another cleaner way to do it? Maybe import into default INBOX and use "doveadm move" instead? Here is my passdb file: (this is a testing setup inside a VM in my laptop) didar:{plain}e5d903c1615cdcd9c3d088ec2cb71b11927f7650:::: jamir:{plain}9ffeba7706846ed6be4e6e52bcc7afd792330874:::: chaitali:{plain}09ce7f54c7fee999a27967b741dc2e5f3950e7e8:::: rajesh:{plain}308059d2078ba123c435ebf7d0f20d8f137330cf:::: samim:{plain}23b82f0b10a802d25f308960c6071b151e3c37b6:::: monibul:{plain}8da4d1ae5e520ff8fadd415cfbfbafc8fcebb367:::: owasim:{plain}7ef9cf46165c4729e09fc142432cd892e3365c44:::: office:{PBKDF2}$1$9b5a900650285343$5000$1d041a5a6caea807e26b8ff4b41e5389bb4b4427::::/opt/mailstore/common/.Office::userdb_mail=maildir:~/ banking:{PBKDF2}$1$429b69dc44c46b33$5000$25a4b4c106c3fa69a6890253aa9163b66f013d48::::/opt/mailstore/common/.Banking::userdb_mail=maildir:~/ gmail:{PBKDF2}$1$4fadc2241bf79ee5$5000$6b6db95f72fbe2d9dcd311fdad6f614302e98da7::::/opt/mailstore/common/.Gmail::userdb_mail=maildir:~/ automail:{PBKDF2}$1$549cf6f14ab5ceb0$5000$a18fe676ca716148ab1ba75f225044a960420bbf::::/opt/mailstore/common/.Automail::userdb_mail=maildir:~/ Here is my dovecot.conf: # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.19.0-13-amd64 x86_64 Debian 10.7 ext4 # Hostname: dovecot.vbox.lan auth_mechanisms = plain login info_log_path = /var/log/dovecot-info.log listen = 10.0.2.90 log_path = /var/log/dovecot.log mail_attachment_dir = /opt/mailstore/attachments mail_location = mdbox:/opt/mailstore/mdboxes/%u mail_plugins = acl namespace { list = children location = maildir:/opt/mailstore/common:INDEXPVT=~/.common prefix = Common/ separator = / subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dai/passwd-imapauth driver = passwd-file } plugin { acl = vfile:/etc/dovecot/dai/global-acl } protocols = imap lmtp service imap-login { inet_listener imap { address = 127.0.0.1 } } service imap { process_limit = 50 } service lmtp { inet_listener lmtp { address = 10.0.2.90 port = 24 } user = vmail } ssl_cert = </etc/dovecot/dai/dai-dovecot.cert ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/dai/passwd-imapauth default_fields = uid=vmail gid=vmail home=/opt/mailstore/mdboxes/%u driver = passwd-file } protocol imap { mail_max_userip_connections = 2 mail_plugins = acl imap_acl } protocol lmtp { auth_username_format = %n } -- It's all in the mind, ya know.

Obtaining the IMAP GUID from a sieve script
by Ron Garret 02 Feb '21

02 Feb '21

Is there any way to obtain the IMAP GUiD of a message that is being processed by a sieve script? I’m writing a filter that needs to to keep track of message identities as they are moved around between folders. I could add my own id header, but I’d rather not have to reinvent that wheel. Thanks, rg
