New to dovecot admin, question about using LDAP for user-specific values
by Gerben Wierda 13 Sep '19

13 Sep '19

I am new to dovecot administration. I’ve read the Wiki but that hasn’t given me the understanding I need. When I query my LDAP (on macOS) on a value for user ‘gerben’, I can get that: dumbledore:~ gerben$ dscl /LDAPv3/127.0.0.1 -read /users/gerben GeneratedUID GeneratedUID: 780D870E-6B00-478E-AB70-3D3307215A82 I would like to use that value in dovecot settings, e.g. something like user_attrs = \ =mail=maildir://Library/Server/Mail/Data/mail/%{ldap:GeneratedUID} Is this possible and if so what do I exactly need to do to get this working?

keywords lost when moving a message in a folder
by wouldsmina 13 Sep '19

Hi, I migrate my dovecot server from Debian 9 to Debian 10 (Dovecot 2.3.4.1), since when I move a message in a folder, keywords systematically disappear. I'm using Thunderbird 60.8.

Outlook 2019 and IMAP
by John Regan 12 Sep '19

12 Sep '19

Hi, We've just upgraded a few of our desktops to use Outlook 2019, and the configuration is different from previous versions. There doesn't appear to be any ability to specify a username in addition to the user's email address. The username is different than the username specified in the email address. I had read about setting auth_username_format, but the user login name is "user" while the email address is user.name(a)company.com. I've included below my dovecot -n config. # 2.3.7.2 (3c910f64b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.2 (7372921a) # OS: Linux 5.1.16-300.fc30.x86_64 x86_64 Fedora release 30 (Thirty) # Hostname: orion.inside.example.com mail_gid = mail mail_home = mail/ mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mail_max_userip_connections = 500 mail_plugins = " listescape" mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational rege x 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 { driver = pam } passdb { driver = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 } process_min_avail = 6 service_count = 0 vsz_limit = 512 M } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { address = 192.168.1.100 port = 995 } } ssl_cert = </etc/letsencrypt/fullchain.pem ssl_cipher_list = ALL:!LOW:!EXP:!aNULL:!RC4::!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { driver = passwd } userdb { driver = passwd }

Re: Gnu sieve vs Dovecot sieve-filter - sieve-filter extremely slow at lda (writing emails to local mbox files)
by Zenaan Harkness 12 Sep '19

12 Sep '19

I am wondering why sieve-filter is so slow compared to gnu sieve. I run mpop (like getmail) to download from a pop3 server to a local mbox file: ~/mail/email-incoming-unsorted This step is very fast. The next step, I throw the email-incoming-unsorted mbox file at a sieve processor, to sort the emails from that mbox, into other mboxes, according to the sieve rules file. Up until a couple days ago I was using Gnu sieve. Gnu sieve balks on emails which have no x-message-id (?? something like this) header field, so after a few years, I finally decided to switch "up" to Dovecot/Pigeonhole's "sieve-filter" command. Using Gnu sieve, this mbox sorting step was even faster than mpop (/ getmail) - and mpop and getmail are really fast (compared with fetchmail), since they pipeline the email downloads. Even with 100s of emails, Gnu sieve would take only 10 to 20 seconds at most. Super fast. Using sieve-filter, all emails are being processed - including those without "message id header". This is good. But also, using sieve filter, is really slower - slower than the download step by an order of magnitude or two. See below for details, any ideas appreciated. To add to the below, I added: mbox_very_dirty_syncs = yes to the sieve-filter config, which slightly improves performance, but not by much (in comparison with Gnu sieve).

On another test run of ~600 emails, sieve-filter is consistently running ~100% of one CPU (for about 4 minutes) to process these emails, which leads to the conclusion that despite what looks like should be a batch process, sieve-filter is perhaps reloading the rules for every single email that it processes, even though I gave it a whole mbox, and not a single email, to process. Can sieve-filter work the way it should / the way I want it / batch process a whole mbox - without reloading the sieve rules for every email? ----- End forwarded message -----

WARNING: using attachment_dir with plugin zlib can corrupt mails
by Patrick Cernko 12 Sep '19

12 Sep '19

Hello list, hello Dovecot developers, this week, I discovered a serious bug in Dovecot, that lead to several broken mails on our servers. The bug corrupts the first few characters of the mail header during saving. On our setup, it was almost always only the very first line of text, that was corrupted. Depending on the IMAP client (they seem to request different header fields, ... during mail access), the bug causes the imap process to hang up the TCP connection and log errors like this: > imap(USERNAME)<4767><TeQP4ASOTK5/AAAB>: Error: Corrupted record in index cache file /IMAP/mail/mailboxes/USERNAME/mdbox/mailboxes/Trash/dbox-Mails/dovecot.index.cache: UID 489113: Broken fields in mailbox Trash: read(attachments-connector(zlib(/IMAP/mail/mailboxes/USERNAME/mdbox/storage/m.813))): FETCH BODY[HEADER.FIELDS (RETURN-PATH SUBJECT)] got too little data: 2 vs 122 In our case that finally grabbed my attention, the client was the users iphone that did not display any new messages but his Thunderbird did. The bug seems to be triggered by a bad "interaction" of attachment_dir option and zlib plugin. If you use both, you most likely are affected, too, except you only use zlib plugin for reading previously compressed stored mails. That's also the workaround we use now: zlib plugin only enabled in mail_plugins but no plugin/zlib_save set. The bug occurs on very specific mails. Due to privacy reasons I could not provide sample mails here. Storing such mails seems to trigger the bug reproducible. I attached a very minimal doveconf -n config, that can be used to trigger the bug. If one of the developers is interested, I can try to generate an "anonymized" version of such a specific mail that still causes the issue. I discovered the bug on our productive systems, running latest Dovecot 2.2 release, but the latest 2.3 I used during debugging is affected, too. During debugging, I also found one hint, that might help find the bug: If you store a problematic mail with zlib_save=gz (or zlib_save=bz2) and then disable the zlib plugin in mail_plugins, you can call doveadm fetch -u test hdr all | grep -v ^hdr: | gzip --decompress on test's mailbox with only that one broken mail. This will display the beginning of the rfc822 mail text until gzip terminates with "gzip: stdin: unexpected end of file", approximately after twice the length of the mail HEADER. This might indicate, that dovecot stores the uncompressed size of the header in it's data structures although the mail is stored compressed. I also found a very efficient way to find all affected mails in our setup: doveadm -f flow fetch -A 'user guid mailbox uid seq flags hdr' all | \ grep -a "^[^ ]+ user=" | \ grep -avF ' hdr=Return-path: ' | \ grep -av '.* hdr=[[:print:][:space:]]*$' (runtime for ~6M mails on our servers was 20-30min) This can be even more optimized if you have a powerful storage system with GNU parallel: > doveadm user '*' | parallel "doveadm -f flow fetch -u '{}' 'user guid mailbox uid seq flags hdr' all | grep -a '^user=' | grep -avF ' hdr=Return-path: ' | grep -av '.* hdr=[[:print:][:space:]]*$' || true" (runtime for ~6M mails on our servers was ~4min) The command will give you a list of mails that possibly are affected, check the full output of doveadm fetch -u USERNAME hdr guid GUID | less to verify that the header is really broken. On our systems I found 39 mails within ~12M mails. I was able to recover these mails "manually" by reconstructing the Return-Path header line, importing the fixed mails and expunging the corrupt ones. Before importing, I had to disable zlib_save option obviously.

Re: Gnu sieve vs Dovecot sieve-filter - sieve-filter extremely slow at lda (writing emails to local mbox files)
by Zenaan Harkness 12 Sep '19

12 Sep '19

(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
