I am investigating whether dovecot(https://github.com/dovecot/core/) handles case insensitive Message-ID headers as per RFC. I can't raise a support issue with cPanel team (https://tickets.cpanel.net/review/login.cgi) as that needs an paid account with them. There may be an issue with the CPANEL/WHM DKIM module. Is the source code online? Rob

How do I enable sieve trace debugging?
by Graham Leggett 14 Oct '20

14 Oct '20

Hi all, I want to enable trace debugging for sieve. Most specifically, I want to know what sieve scripts are running, and whether they’re doing anything. I cannot get anything other than dead silence from dovecot with respect to sieve. I have tried the same as asked in this question: https://unix.stackexchange.com/questions/550618/dovecot-sieve-trace-does-no… In my case, the config looks like this: ## TRACE DEBUGGING # Trace debugging provides detailed insight in the operations performed by # the Sieve script. These settings apply to both the LDA Sieve plugin and the # IMAPSIEVE plugin. # # WARNING: On a busy server, this functionality can quickly fill up the trace # directory with a lot of trace files. Enable this only temporarily and as # selective as possible. # The directory where trace files are written. Trace debugging is disabled if # this setting is not configured or if the directory does not exist. If the # path is relative or it starts with "~/" it is interpreted relative to the # current user's home directory. sieve_trace_dir = /tmp/sieve-trace # The verbosity level of the trace messages. Trace debugging is disabled if # this setting is not configured. Possible values are: # # "actions" - Only print executed action commands, like keep, # fileinto, reject and redirect. # "commands" - Print any executed command, excluding test commands. # "tests" - Print all executed commands and performed tests. # "matching" - Print all executed commands, performed tests and the # values matched in those tests. sieve_trace_level = actions,command,tests,matching # Enables highly verbose debugging messages that are usually only useful for # developers. sieve_trace_debug = yes This looks sensible, syslog would be a great place to log, but nothing related to sieve appears.

Changing IMAP separator - does it break things?
by Victor Sudakov 14 Oct '20

14 Oct '20

Dear Colleagues, I am using Dovecot 2.3.4.1 with maildirs. Just found out that MacOS Mail clients cannot work with nested folders, presumably because the MacOS Mail does not understand "." as the IMAP separator. Other clients (ThunderBird, Sylpheed, mutt) work fine. Do you think I can change the hierarchy separator in the "inbox" namespace without breaking other clients and the mail layout on disk, losing mail etc? I don't want to break mail for 50 people just to please one Mac Mail user. The users are advanced developers actively using mail sorting rules, nested folders etc. My `doveconf -n` is here: https://termbin.com/w1wd -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/

Re: Fatal: setgid from userdb lookup fails with wrong gid

Hi, Not sure if this is it, but I used to have the same error when I started with dovecot. Aki's response was the following (and solved my problem). ------------- Hi! You can't set service imap { service_count = 256 } if you are using multiple system UIDs. See https://wiki.dovecot.org/Services#imap.2C_pop3.2C_submission.2C_managesieve *service_count* can be changed from 1 if only a single UID is used for mail users. This is improves performance, but it's less secure, because bugs in code may leak email data from another user's earlier connection.

It would be nice to know if there are any zstd or zlib compressed mails that have problems. We did a lot of stress testing with zstd and also with xz, but haven't been able to reproduce any problems. It's also strange that it says taht the error is "Broken pipe" - that doesn't indicate that the mail is corrupted but that there is something more strange going on. So perhaps you don't actually have any mails written as corrupted, but Dovecot is just somehow having trouble reading the mails. I managed to reproduce this. The files aren't corrupted, it's just that reading is failing. The attached patch should fix the xz code and should make your files readable again. Yes, it works ! I switched now to "zstd" compression and currently re-compressing all user imap folders (one by one) Actually, with further testing it looks like the mails were written truncated. My patch simply hides the truncation when reading the mail. But it's anyway best that can be done about them. zstd also has a bug in writing compressed output, but it should always crash instead of writing broken output. We'll try to get fixes to these merged to git soon. currently I am re-compressing the mailboxes and so far i can see only one (1) Error, after about 120GB of recomresses emails : Sep 10 11:32:24 lxc-imap dovecot: imap(ebay)<37070><1aDvPvKus+/AqKjk>: Panic: file ostream.c: line 287 (o_stream_sendv_int): assertion failed: (!stream->blocking) Sep 10 11:32:24 lxc-imap dovecot: imap(ebay)<37070><1aDvPvKus+/AqKjk>: Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(backtrace_append+0x41) [0x7f5b00de6da1] -> /usr/local/lib/dovecot/libdovecot.so.0(backtrace_get+0x22) [0x7f5b00de6ec2] -> /usr/local/lib/dovecot/libdovecot.so.0(+0xfe5eb) [0x7f5b00df05eb] -> /usr/local/lib/dovecot/libdovecot.so.0(+0xfe687) [0x7f5b00df0687] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x598e1) [0x7f5b00d4b8e1] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x5e2c1) [0x7f5b00d502c1] -> /usr/local/lib/dovecot/libdovecot.so.0(o_stream_sendv+0x32) [0x7f5b00e14a92] -> /usr/local/lib/dovecot/libdovecot.so.0(io_stream_copy+0x5a) [0x7f5b00e1535a] -> /usr/local/lib/dovecot/libdovecot.so.0(o_stream_send_istream+0x50) [0x7f5b00e15060] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(index_storage_save_continue+0x2d) [0x7f5b00f9659d] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(dbox_save_continue+0x30) [0x7f5b00f3d3b0] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_save_continue+0x3e) [0x7f5b00f1a34e] -> dovecot/imap [ebay 192.168.168.228 APPEND](+0x13801) [0x55d6905bf801] -> dovecot/imap [ebay 192.168.168.228 APPEND](command_exec+0x6c) [0x55d6905ce3ec] -> dovecot/imap [ebay 192.168.168.228 APPEND](+0x12fdb) [0x55d6905befdb] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x6d) [0x7f5b00e06ced] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x145) [0x7f5b00e08305] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x54) [0x7f5b00e06d94] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x48) [0x7f5b00e06f08] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x17) [0x7f5b00d7f8d7] -> dovecot/imap [ebay 192.168.168.228 APPEND](main+0x459) [0x55d6905bec99] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf3) [0x7f5b00b0e0b3] -> dovecot/imap [ebay 192.168.168.228 APPEND](_start+0x2e) [0x55d6905bed2e] Sep 10 11:32:24 lxc-imap dovecot: imap-login: Panic: epoll_ctl(del, 21) failed: Bad file descriptor Sep 10 11:32:24 lxc-imap dovecot: imap(ebay)<37070><1aDvPvKus+/AqKjk>: Fatal: master: service(imap): child 37070 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps) until now I only have one broken mailbox, I need to repair (I will try that later, just finish all the other users before): Sep 10 12:13:13 lxc-imap dovecot: imap(mtrenner)<41872><KVTf0PKu7+7AqKi0>: Error: lzma.read(/home/vmail/virtualmailboxes/mtrenner/storage/m.349): corrupted data at 3763912 Sep 10 12:13:13 lxc-imap dovecot: imap(mtrenner)<41872><KVTf0PKu7+7AqKi0>: Error: Mailbox Sent: UID=1480: read(zlib(/home/vmail/virtualmailboxes/mtrenner/storage/m.349)) failed: read(/home/vmail/virtualmailboxes/mtrenner/storage/m.349) failed: lzma.read(/home/vmail/virtualmailboxes/mtrenner/storage/m.349): corrupted data at 3763912 (FETCH BODY[]) > zstd also has a bug in writing compressed output, but it should always crash instead of writing broken output. > We'll try to get fixes to these merged to git soon.

Spam learning for rspamd
by Dan Egli 14 Oct '20

14 Oct '20

I'm quite new to Dovecot, so forgive me if this is a simple question. I've got rspamd running, and it's rewriting the subject of many messages as spam even when they are not. I've moved things out of the spam folder, which I was under the impression would teach rspamd since I've connected a sieve script that is supposed to call rspamd's learning tool, but nothing is happening. I'm really at a loss as to where to even begin searching for an answer, so any help is appreciated! -- Dan Egli On my Test server

Procmail with Dovecot
by Dan Egli 13 Oct '20

13 Oct '20

Hey folks, here's a question. I want to enable procmail for the users so that they can have their incoming messages sorted info various folders and such regardless of MUA access or web access. I know I can set procmail to deliver to a maildir, but wouldn't that screw up dovecot's indexes? If it would, what can I do to ensure that the indexes stay correct? Thanks! -- Dan Egli On my Test server

Move older messages to Old folder after a bunch of changes (sql + other stuff)
by Chris Bennett 13 Oct '20

13 Oct '20

I'm starting to get things better done now. Moved to all virtual users over IMAP. Using a SQL database for users/passwords. Setting up folders working properly with neomutt. Right now, that leaves me with just new mail in the INBOX, and other folders. I have a bunch of old mail in each users Maildirs in their real home folders. Right now, I'd like to move all the old mail into a folder (doesn't really matter what it's called). Right now is actually a perfect time to do this by good luck in timing. How should I go about creating a new folder for those messages and then adding the old mail from system user home Maildir folders to the virtual users folders I'm using? Thanks for any help, Chris Bennett
