Dovecot process died with assertion failed
Hi, I'm testing Dovecot v2.3.9.2. So, I found a problem that a Dovecot process termed with Panic, like below: Feb 10 08:50:09 imap(us...@example.com)<38440>: Panic: file message-snippet.c: line 71 (snippet_add_content): assertion failed: (*count_r <= size) Feb 10 08:50:09 imap(us...@example.com)<38440>: Error: Raw backtrace: /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(backtrace_append+0x3b) [0x7fee4c46331b] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7fee4c46346e] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(+0xfc90b) [0x7fee4c46f90b] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(+0xfc9c1) [0x7fee4c46f9c1] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fee4c3b470a] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(+0xdea53) [0x7fee4c451a53] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot-storage.so.0(+0xdcd98) [0x7fee4c80bd98] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot-storage.so.0(+0xdd1a5) [0x7fee4c80c1a5] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot-storage.so.0(index_mail_get_special+0x2c1) [0x7fee4c80c591] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot-storage.so.0(dbox_mail_get_special+0x48) [0x7fee4c7adeb8] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot-storage.so.0(+0x78f2b) [0x7fee4c7a7f2b] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot-storage.so.0(mail_get_special+0x10) [0x7fee4c76f3e0] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](+0x2645b) [0x55ffc6c5845b] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](+0x239df) [0x55ffc6c559df] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](imap_fetch_more+0x35) [0x55ffc6c578b5] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](cmd_fetch+0x35f) [0x55ffc6c44aaf] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](command_exec+0xb9) [0x55ffc6c535b9] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](+0x1eacf) [0x55ffc6c50acf] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](+0x1eb87) [0x55ffc6c50b87] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](client_handle_input+0x215) [0x55ffc6c51885] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](client_input+0x7e) [0x55ffc6c5206e] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x7b) [0x7fee4c48bcdb] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x105) [0x7fee4c48dd55] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x59) [0x7fee4c48bde9] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fee4c48c098] -> /usr/local/dovecot-2.3.9.2/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fee4c3e9623] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](main+0x367) [0x55ffc6c40d37] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7fee4bfc7545] -> dovecot-backend-server/imap [us...@example.com 10.16.2.10 UID FETCH](+0xefb4) [0x55ffc6c40fb4] Feb 10 08:50:09 imap(us...@example.com)<38440>: Fatal: master: service(imap): child 38440 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps) It was occurred this by a mail had ISO-2022-JP content (Single part mail). I saw that the mail was not strange. When I appended the mail with IMAP APPEND command, that no problem happened. I think the problem comes by LMTP only. Any idea?

Very slow mail download/notification with dovecot 2.2.33 and Thunderbird
Hi! I know that there are many results if I search for "dovecot thunderbird very slow" on Google but none of them helped me with my problem. :( I am running Ubuntu 18.04 (4GB RAM, 40GB HDD with EXT4) with the following software: - Dovecot 2.2.33 All accounts are using Maildir Sieve filters - Postfix 3.3.0 with opendkim, spamassassin, razor, pyzor, And as IMAP client I am using Thunderbird 68.4 on Windows10. Sieve is used to sort incoming mails into my 224 folders (56 INBOX. folders and its subfolders (output of "find .INBOX.* -maxdepth 4 -type d -print |wc -l")). My problem is that it takes very very long to synchonize the INBOX and its subfolders. Even if there are only a few new messages to be downloaded. Sometimes Thunderbird outputs something like "downloading message 1 of 19" and it takes at least 60 seconds to download all of them. None of these 19 mails is larger than 5kB. And sometimes it seems that the transfer is suspended for a long time and it takes >5 Minutes to synchronize only a few mails. :( Every helpful advice is welcome. I just don't know where to look for the cause right now, but I can provide configurations (like output of |doveadm config) |and some logfiles. Thank you very much! Thorsten

Re: [v 2.3.4.1][quota] recalculation
Hi Sami, You are right ! Event if emails are deleted from trash (and so: they do not appears in thunderbird anywere), they are not expunged ! Right clic on trash > empty trash will send expunge signal to server ! Thanks a lot !

Re: [v 2.3.4.1][quota] recalculation
Hi, Does thunderbird even delete the mail from storage if you delete it from UI? Most imap clients with default configuration just flag the mail \Deleted but do not actually expunge if from server. In Apple Mail.App that I use there is "Erase Deleted Items" to actually expunge mails previously flagged \Deleted.

[v 2.3.4.1][quota] recalculation
Hello, I can't find the information on the wiki :( When is the quota recalculated after a mail deletion ? For instance, I am running low of storage and I use Thunderbird to delete large mail. I only notice a recalculation when I quit Thunderbirdb and I relaunch it. Even, with doveadm CLI, as long as Thunderbird is not disconnected on the client side, the server didn't recalculate the storage available. Thanks for the help !
