Per the Dovecot site here: https://wiki.dovecot.org/Plugins/MailCrypt ... the "decrypt.rb" ruby script can be used to decrypt a Dovecot-encrypted message file from the command line. The script sort of runs successfully for me, in the sense that it doesn't error out, but it doesn't show the decrypted message. I've called it like so: decrypt.rb -k <PATH_TO_DOVECOT_KEYFILE> -f ./encrypted_message But when I do it just displays the info below and exits (I've subbed <DATA> … [View More]

Shared mailboxes, users with dots and a bug in subscriptions
by Tobias Stein 17 May '22

17 May '22

Hi, i'm running Dovecot 2.3.14.alpha0 with shared namespaces and stumbled across some errors messages logged, when the list of subscribed mailboxes is queried by a client. For every distinct account of in the list of subscriptions two corresponding lines are logged: Jan 28 11:42:34 mx1 dovecot: auth: missing passwd file: /etc/dovecot/private/example/users Jan 28 11:42:34 mx1 dovecot: auth: missing passwd file: /etc/dovecot/private/example/users Jan 28 11:42:34 mx1 dovecot: auth: missing … [View More]passwd file: /etc/dovecot/private/example/users Jan 28 11:42:36 mx1 dovecot: imap(example_user(a)example.com)<3638><xl6li/O5VsVfWxyn>: Error: mkdir(/var/run/dovecot/user-not-found/noc@example) failed: Permission denied (euid=109(vmail) egid=118(vmail) missing +w perm: /var/run/dovecot, dir owned by 0:0 mode=0755) Jan 28 11:42:36 mx1 dovecot: imap(example_user(a)example.com)<3638><xl6li/O5VsVfWxyn>: Error: mkdir(/var/run/dovecot/user-not-found/info@example) failed: Permission denied (euid=109(vmail) egid=118(vmail) missing +w perm: /var/run/dovecot, dir owned by 0:0 mode=0755) Jan 28 11:42:36 mx1 dovecot: imap(example_user(a)example.com)<3638><xl6li/O5VsVfWxyn>: Error: mkdir(/var/run/dovecot/user-not-found/root@example) failed: Permission denied (euid=109(vmail) egid=118(vmail) missing +w perm: /var/run/dovecot, dir owned by 0:0 mode=0755) Similar messages are logged, when invalid entries are listed in '/var/lib/dovecot/db/shared-mailboxes', which i already pruned and haven't received them anymore since. I think these errors are caused by an unintended behaviour when writing "~/Maildir/subscriptions", which looks (shortened) like this. V 2 INBOX/INBOX shared/noc@example com/INBOX shared/info@example com/INBOX shared/root@example com/test shared/root@example com/test test_sub The subscription-file.c explodes the name on every hierarchy separator ('.','\0') and inserts a TAB character. Unfortunately it also explodes on the DNS label delimiter „.‟. This should probably be fixed by passing a structure containing the required information to the formatter to distinguish mailboxes from domain-names. Subscription in combination with multiple domains and shared mailboxes seems broken to me. Actually i can't even explain to me, why it is working in face of the errors. :-) Unfortunately in Maildir++ the separator dot is hard-coded. There is a very old thread on this mailing list, that suggests using „auth_username_translation‟ to replace dots with a different character, but this idea is getting worse the longer i think about it. I absolutely dislike the idea to set LAYOUT=fs, namespace/separator = § to change the separators to split on, because this would mean to restructure the physical layout of all mailboxes (hierarchically) and mess around with lots of files. I attached a dovecot-sysreport to reproduce the behaviour. /etc/dovecot/private/example.com/users looks like this: ### user:password:uid:gid:(gecos):home:(shell):extra_fields noc:{SSHA512}_hash_:::::: info:{SSHA512}_hash_:::::: root:{SSHA512}_hash_:::::: Please correct me if i'm wrong or point me to a workaround, but i think the layout code needs some love. :-) Best regards Tobias [View Less]

Dsync replication - delayed replication (Sync lock)
by Daniel Botting 31 Jan '22

31 Jan '22

Hi, *Our setup:* Two Debian 10 machines that are setup to replicate mail between them, we have round robin DNS setup so a user can connect to either server. *What should happen:* Mail is delivered to either server and replicated across straight away to their mailbox on the other server so it does not matter which one they are connected to they will receive it fairly soon after delivery. *What actually happens:* In some instances the user will experience a delayed receipt of messages … [View More]if they are not connected to the server that the message is initially delivered to, sometimes the delay is 5/10 minutes, we had a recent support ticket submitted where it was over an hour.

Mailbox problem on centos O/S after some "fiddling"
by John Richards 28 May '21

28 May '21

Good day from Somerset, England Version 2.2.10 Problem after a huge centos update Data:- Server has 8 mailboxes under /var/mail/"user name" history:- After update, mail to ONE user was going into mqueue as undeliverable Had to delete and recreate the user. somewhere along the line (ME!) /var/mail/;imap var/mail/new were deleted After new user and reboot server no one could access mailboxes with password error except ONE user randomly...… [View More].This created the /var/mail/.mbox folder and sub folders but with the owner as the user name. Then any mail for other users was put in the /var/new folder and just sat there. only the "owner" of this folder could get mail, everyone else was prohibited with password error. chown the folder (owner:group) to root did nothing BUT When .mbox was give PUBLIC execute permissions (771) suddenly everything works fine! I do not understand why dovecot creates this folder as we ONLY ever use pop3 (currently with plain text auth but going to secure when this sorted) for mail and also why when it writes the blank folder it "owns" it with the user accessing it (also the /var/mail/new folder takes the same owner) I have trolled everywhere and spent a whole day on this so any clues would be very gratefully accepted as do not like to leave this folder as 771 (note the folder INBOX within it is only 770 and the log file in that is 660) Is this INBOX needed at all for pop3 ? rgds John Richards UK ================= dovecot -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-514.2.2.el7.x86_64 x86_64 CentOS Linux release 7.3.1611 (Core ) ext4 auth_mechanisms = plain login disable_plaintext_auth = no mail_location = mbox:/var/mail/:INBOX=/var/mail/%u 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 = shadow } protocols = pop3 service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/pki/tls/certs/watchetwebdesign.co.uk.crt ssl_key = </etc/pki/tls/private/watchetwebdesign.co.uk.key userdb { driver = passwd } [View Less]

IMAP session hangs on 8k-long commands if COMPRESS=DEFLATE is enabled
by Guilhem Moulin 21 Apr '21

21 Apr '21

Hi there, Dovecot 2.3.7 appears to hang when the client sends a long command after enabling the IMAP COMPRESS extension [RFC 4978]. PoC script attached along with the doveconf(1) output. Without COMPRESS=DEFLATE, and with the default ‘imap_max_line_length’ value (64k) I'm able send commands up to 65539 bytes long (that's 3 bytes more than 2¹⁶, so maybe the leading tag and the trailing CRLF aren't counted), after which Dovecot rightfully replies with tagged BAD responses. $ COMPRESS=n /… [View More]tmp/many-fetch.pl 65539 […] C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [65539 bytes] S: x OK Fetch completed (0.005 + 0.001 + 0.004 secs). C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [65540 bytes] S: x BAD Error in IMAP command UID FETCH: IMAP command line too large (0.001 + 0.001 secs).

With COMPRESS=DEFLATE however, the server never sends anything back when the command size exceeds 8192 bytes: $ COMPRESS=y /tmp/many-fetch.pl 8192 […] S: x OK [READ-ONLY] Examine completed (0.001 + 0.000 secs).

Interestingly, when setting ‘imap_max_line_length’ to 4096, the server also hangs after receiving a command of size >4096 bytes (instead of replying with a tagged BAD response). $ COMPRESS=y /tmp/many-fetch.pl 4096 C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [4095 bytes] S: x OK Fetch completed (0.001 + 0.000 secs).

C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [4097 bytes] [ _hangs until the server terminates the session for inactivity_ ] I'm also able to reproduce the buggy behavior against Dovecot versions found in other Debian releases. It's identical with 2.3.4 (Buster), the server also hang past 8192 bytes. 2.2.27 (Stretch) and 2.2.13 (Jessie) are able to send replies to 8k-long commands, but hang past 65536 bytes. For all 3 releases, without COMPRESS=DEFLATE Dovecot doesn't hang and rightfully sends tagged BAD responses to commands of size >65539 bytes. So while the hanging behavior appears to be a long-standing bug, the fact that's it's now hit at min($imap_max_line_length, 8192) instead of $imap_max_line_length seems to be a regression from somewhere between 2.2.27 and 2.3.4.

Only INBOX is searched when using gmail with dovecot FTS and solr

Hi, I am using https://github.com/docker-mailserver/docker-mailserver to setup my mailserver and added solr for full-text search. Nearly everything is working as expected. But I have a problem with the full-text search, as I have a lot of folders in my mailbox and I just can't find any mail in any of these folders except INBOX when I search with the Gmail android app. After analyzing the logs, I assume, that the bug is in the Gmail app, as it is only searching in the INBOX folder.

json_parse_number broken by compiler optimization

Hi, the recent Ubuntu (re)builds uncovered an issue with dovecot 1:2.3.13+dfsg1-1 build log: https://launchpadlibrarian.net/529849650/buildlog_ubuntu-hirsute-amd64.dove… A coworker tried 2.3.14 but got the same result. What fails is the json_parser build time test like: test-json-parser.c:161: Assert(#25) failed: null_strcmp(json_output[pos].value, value) == 0 I was looking into that a bit more and what I found is that it is dependent on the new toolchain of gcc 10.2.0-1.

A breakpoint on str_append_c and backtraces showed that we clearly do the "right" parsing. From the backtraces I've seen it does (just from positions): For example (gdb) bt #0 str_append_c (chr=<optimized out>, str=0x5555556930d0) at str.h:44 #1 json_parse_digits (parser=<optimized out>) at json-parser.c:366 => that is a digit It does "- digit digit dot digit digit digit" This perfectly matches the input value, but still the result stays empty: (gdb) p (char*)(str->data) $738 = 0x555555693110 "" In comparison - when parsing the latter 12.456e9 which works I see two odd things: 1. the value isn't cleared despite str_truncate(parser->value, 0); at the beginning of json_parse_number 2. the value (this time) is read exactly as I assumed Breakpoint 17, json_parse_number (value_r=0x7fffffffe1a0, parser=0x555555692ee0) at json-parser.c:394 394 str_truncate(parser->value, 0); Breakpoint 18, str_append_c (chr=<optimized out>, str=0x5555556930d0) at str.h:44 44 buffer_append_c(str, chr); (gdb) p (char*)(str->data) $741 = 0x555555693110 "sub3" ^^ not cleared, still has "sub3" even later on Breakpoint 18, str_append_c (chr=<optimized out>, str=0x5555556930d0) at str.h:44 44 buffer_append_c(str, chr); (gdb) p (char*)(str->data) $742 = 0x555555693110 "1ub3" ^^ reading left to right one char at a time "over the old value", which didn't update the data. So it seems in json_parse_number the ordering of a) str_truncate(parser->value, 0); b) the parsing itself is messed up by optimization. We already know from the above that reducing just this function to -O1 or less avoids the issue. But what is it really - I don't know? Maybe you have a better idea what is going on, the issue should be reproducible when building dovecot with the toolchain present on the latest Ubuntu being 21.04 (Hirsute) right now. -- Christian Ehrhardt Staff Engineer, Ubuntu Server Canonical Ltd [View Less]

We get the error "User initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:bytes=: Invalid bytes limit:" /mar 16 10:29:27 lda(user@domain): Quota: Executing warning: quota-warning 90 user@domain// //Mar 16 10:29:27 buzonn5 gonzalo: mar 16 10:29:27 lda(user@domain): Quota: Executing warning: quota-warning 90 user@domain// //Mar 16 10:29:27 … [View More]buzonn5 dovecot: lda(user@domain): Debug: Loading modules from directory: /usr/lib64/dovecot// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: Module loaded: /usr/lib64/dovecot/lib15_notify_plugin.so// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: Module loaded: /usr/lib64/dovecot/lib20_mail_log_plugin.so// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: Module loaded: /usr/lib64/dovecot/lib90_sieve_plugin.so// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: auth USER input: user@domain home=/buzones/externos/4/215283255776546 uid=508 gid=503 quota_rule=*:bytes=2147483648// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: Ignoring overridden (-o) userdb setting: plugin/quota_rule// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: Effective uid=508, gid=503, home=/buzones/externos/4/215283255776546// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: Quota root: name=_backup backend=maildir args=ns=// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Debug: Quota rule: root=_backup mailbox=* bytes=0 messages=0// //Mar 16 10:29:27 buzonn5 dovecot: lda(user@domain): Error: User initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:bytes=: Invalid bytes limit:// //Mar 16 10:29:27 buzonn5 dovecot: lda: Fatal: Invalid user settings.
