argonid and dovecote
by Jerry 06 Dec '18

06 Dec '18

on a FreeBSD 11.2 amd64 machine, I am trying to get Dovecot 2.3.4 to play nice with "argonid" encryption. In the "10-auth.conf" file, I tried: auth_mechanisms = plain argon2id Upon restarting dovecot, I received an error message when attempting to actually it: auth: FATAL: Unknown authentication mechanism "ARGON2ID" Output from doveadm pw -l doveadm pw -l SHA1 SSHA512 BLF-CRYPT PLAIN HMAC-MD5 OTP SHA512 SHA RPA DES-CRYPT CRYPT SSHA MD5-CRYPT SKEY PLAIN-MD4 PLAIN-MD5 SCRAM-SHA-1 LANMAN SHA512-CRYPT CLEAR CLEARTEXT ARGON2I ARGON2ID SSHA256 NTLM MD5 PBKDF2 SHA256 CRAM-MD5 PLAIN-TRUNC SHA256-CRYPT SMD5 DIGEST-MD5 LDAP-MD5 I assume I am making a stupid mistake, but I do not know what it is. -- Jerry

Dovecot 2.3.4 crashing on Solaris 10 - "Panic: output stream is missing error handling"
by Fabian Fritz 06 Dec '18

06 Dec '18

Hi, I just compiled Dovecot for Solaris 10 and try to run it now. Other than setting a custom port, I did not add custom settings. When I tried running doveconf for the first time, it crashed immediately: doveconf -n # 2.3.4 (): /export/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 sun4u~~ # Hostname: merlin service pop3-login { inet_listener pop3 { port = 1110 } } submission_max_mail_size = 0 doveconf: Panic: output stream is missing error handling doveconf: Error: Raw backtrace: 0xff01b3a8 -> 0xff063b04 -> 0x1673c -> 0x1797c -> 0x14478 Abort (core dumped) The same error appears when I run dovecot -F. Unfortunately I currently don't have access to the core dumps (I might do later), but I could run it with the Debugger with user process debugging enabled: (This is the part when it crashes. I can provide the full output if requested) truss -u "libdovecot" /export/dovecot/bin/doveconf -n service pop3-login { inet_listener pop3 { port = 1110 } } submission_max_mail_size = 0 /1: write(1, " s e r v i c e p o p 3".., 95) = 95 /1@1: <- libdovecot:o_stream_uncork() = 0xa1918 /1@1: -> libdovecot:buffer_free(0xa1a10, 0x0, 0x0, 0x0) /1@1: -> libdovecot:pool_system_free(0xff0fb050, 0x4af10, 0xff0fb030, 0xff059470) /1@1: <- libdovecot:buffer_free() = 0 /1@1: -> libdovecot:buffer_free(0xa1a18, 0x1c00, 0xfec47940, 0x0) /1@1: -> libdovecot:pool_system_free(0xff0fb050, 0x4af60, 0xff0fb030, 0xff059470) /1@1: <- libdovecot:buffer_free() = 0 /1@1: -> libdovecot:pool_datastack_create(0xc3ed8, 0xc4200, 0x328, 0x0) /1@1: <- libdovecot:pool_datastack_create() = 0x42a58 /1@1: -> libdovecot:buffer_create_dynamic(0x42a58, 0x20, 0x8000, 0xff0f44f4) /1@1: <- libdovecot:buffer_create_dynamic() = 0x42a68 /1@1: -> libdovecot:buffer_append(0x42a68, 0x525c8, 0x4, 0x42a68) /1@1: -> libdovecot:buffer_write(0x42a68, 0x0, 0x525c8, 0x4) /1@1: <- libdovecot:buffer_append() = 0x42a88 /1@1: -> libdovecot:array_sort_i(0xffbfec38, 0x1cd70, 0x0, 0x52830) /1@1: <- libdovecot:array_sort_i() = 0x42a88 /1@1: -> libdovecot:buffer_append_space_unsafe(0x42a68, 0x4, 0x4, 0x1cd70) /1@1: -> libdovecot:buffer_get_space_unsafe(0x42a68, 0x4, 0x4, 0x1cd70) /1@1: <- libdovecot:buffer_append_space_unsafe() = 0x42a8c /1@1: -> libdovecot:o_stream_uncork(0xa1968, 0xffbfedb0, 0x0, 0x1) /1@1: <- libdovecot:o_stream_uncork() = 0xa1918 /1@1: -> libdovecot:o_stream_destroy(0xffbfed3c, 0x0, 0x0, 0x1) /1@1: -> libdovecot:o_stream_unref(0xffbfed3c, 0x0, 0x0, 0x1) doveconf: Panic: output stream is missing error handling /1: write(2, " d o v e c o n f : P a".., 58) = 58 /1: getcontext(0xFFBFE988) /1: open("/proc/self/as", O_RDONLY) = 8 /1: fstat64(8, 0xFFBFE7B8) = 0 /1: pread(8, "FFBFEB H", 4, 0xFFBFE958) = 4 /1: pread(8, "FF\0CBD0", 4, 0xFFBFE95C) = 4 /1: pread(8, "FFBFEBA8", 4, 0xFFBFEB80) = 4 /1: pread(8, "FF01B11C", 4, 0xFFBFEB84) = 4 /1: pread(8, "FFBFEC\b", 4, 0xFFBFEBE0) = 4 /1: pread(8, "FF01B3A8", 4, 0xFFBFEBE4) = 4 /1: pread(8, "FFBFEC80", 4, 0xFFBFEC40) = 4 /1: pread(8, "FF06 ;04", 4, 0xFFBFEC44) = 4 /1: pread(8, "FFBFECE0", 4, 0xFFBFECB8) = 4 /1: pread(8, "\001 g <", 4, 0xFFBFECBC) = 4 /1: pread(8, "FFBFED @", 4, 0xFFBFED18) = 4 /1: pread(8, "\001 y |", 4, 0xFFBFED1C) = 4 /1: pread(8, "FFBFEDF0", 4, 0xFFBFED78) = 4 /1: pread(8, "\001 D x", 4, 0xFFBFED7C) = 4 /1: pread(8, "\0\0\0\0", 4, 0xFFBFEE28) = 4 /1: pread(8, "\0\0\0\0", 4, 0xFFBFEE2C) = 4 /1: close(8) = 0 doveconf: Error: Raw backtrace: 0xff01b3a8 -> 0xff063b04 -> 0x1673c -> 0x1797c -> 0x14478 /1: write(2, " d o v e c o n f : E r".., 90) = 90 /1: sigaction(SIGABRT, 0x00000000, 0xFFBFEB88) = 0 /1: sigaction(SIGABRT, 0xFFBFEA38, 0xFFBFEAD8) = 0 /1: lwp_sigmask(SIG_SETMASK, 0x00000000, 0x00000000) = 0xFFBFFEFF [0x0000FFFF] /1: lwp_kill(1, SIGABRT) = 0 /1: Received signal #6, SIGABRT [default] /1: siginfo: SIGABRT pid=25172 uid=0 code=-1 I have no idea about what that error means.

Restricting sending mail to domain or group
by admin 06 Dec '18

06 Dec '18

Hi folks, has anybody a simple solution for the following request? I have a group alias (all(a)company.com) (1) Only company.com accounts should be able to send an email to everybody in that company via all(a)company.com. (2) - rather optional: refine the restrictions, e.g. two groups, grp1(a)company.com and grp2(a)company.com. Grp1 members should be able to send mails to grp2 but not vice versa. What else than sieve would keep dealing with that demands as simple as possible? Thanks in advance and sorry for abusing this list for this kind of „problem“ which is not a bug. Regards, -M

Error: Corrupted record in index cache file
by Orion Poplawski 05 Dec '18

05 Dec '18

With dovecot-2.2.36-3.el7.x86_64 we had a couple hours where mail_plugins did not properly include zlib for all of the needed services. This seems to have led to some corruption in our mdbox mailboxes. I've run doveadm force-resync on a number of users, but I'm still seeing messages like this: dovecot[13563]: imap(USER): Error: Corrupted record in index cache file /var/spool/imap/USER/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: UID 67976: Broken physical size in mailbox INBOX: read(zlib(/var/spool/mail/USER/storage/m.1203)) failed: Cached message size smaller than expected (2978 < 8192, box=INBOX, UID=67976) Is there anything that can be done about this? Can I safely delete the dovecot.index.cache file? I'm hesitant to do so since I understand that the mdbox format uses the index to store mailbox information and deleting at least some index files is a destructive operation.

vacation script issue
by fins 05 Dec '18

05 Dec '18

Hello, I have a complete Postfix + Dovecot + openLDAP setup almost working, the only issue I have is the vacation script auto-reply that doesn't work properly. If I send an email to a user with the vacation filter enabled, the auto-reply is send to a local recipient with the same account name. So for example if I send a mail from test(a)xyz.com to test(a)example.com, the auto-reply is received on the test(a)example.com address instead of the test(a)xyz.com who's the original sender. Here's a log file: Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): Debug: sieve: executing script from /var/mail/example.com/test/.dovecot.svbin Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): sieve: msgid=< dovecot-sieve-1543841568-836314-0(a)imap.example.com>: discarding vacation response to auto-submitted message from <MAILER-DAEMON> Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): sieve: msgid=< dovecot-sieve-1543841568-836314-0(a)imap.example.com>: stored mail into mailbox 'INBOX' Dec 3 13:52:48 imap postfix/pipe[6663]: D835A300E05: to=<test(a)example.com>, orig_to=<test(a)xyz.com>, relay=dovecot, delay=0.1, delays=0.03/0.01/0/0.06, dsn=2.0.0, status=sent (delivered via dovecot service) Can somebody help with this issue and/or point where to go for debugging?

Random issue on mailbox "assertion failed"
by Thomas Durand 05 Dec '18

Hi, Since few weeks, I have regularly the issue below with some mailboxes - This is happening randomly. Users are complaining emails are not visible. The situation is recovered by removing indexes but I would like to have it fix permanently. Ruuning dovecot 2.2.10 - Anyone to advise me what is wrong ? Thanks.

And what about the "dovecot-keywords" files in both folders? Do they match? The letter "a" seems to indicates that there is at least one non-standard flag defined in the source folder's keywords. By the way, can I assume you move messages only by using Thunderbird/IMAP and not by manipulating the file system? Here's how things look on my server: # On arrival (UNSEEN) 1543968031.M941319P5841.foo,S=1390,W=1422:2, # After reading (SEEN) 1543968031.M941319P5841.foo,S=1390,W=1422:2,S # After being moved to another folder (SEEN) 1543968031.M941319P5841.foo,S=1390,W=1422:2,S I can use IMAP search terms SEEN and UNSEEN as indicated above, and I see the same message state displayed in Notmuch mail (my default, it accesses Dovecot's Maildir storage directly) and various IMAP clients connecting to Dovecot.

dovecot and argon2 encryption
by Jerry 04 Dec '18

I am using a FreeBSD 11-2 amd/64 system with dovecot version 2.3.4 installed. I was playing around with different encryption schemes. doveadm pw -l SHA1 SSHA512 BLF-CRYPT PLAIN HMAC-MD5 OTP SHA512 SHA RPA DES-CRYPT CRYPT SSHA MD5-CRYPT SKEY PLAIN-MD4 PLAIN-MD5 SCRAM-SHA-1 LANMAN SHA512-CRYPT CLEAR CLEARTEXT SSHA256 NTLM MD5 PBKDF2 SHA256 CRAM-MD5 PLAIN-TRUNC SHA256-CRYPT SMD5 DIGEST-MD5 LDAP-MD5 There is no mention of "argon2" shown. Now, from the command line I can enter this command: ~ $ echo -n "Secret-Password" | argon2 somesalt Type: Argon2i Iterations: 3 Memory: 4096 KiB Parallelism: 1 Hash: e6432f595e999988c7c54c30d530b0fc7d9953510e5ccf295359258f4ea22a3d Encoded: $argon2i$v=19$m=4096,t=3,p=1$c29tZXNhbHQ$5kMvWV6ZmYjHxUww1TCw/H2ZU1EOXM8pU1klj06iKj0 0.039 seconds Verification ok However, this fails: doveadm pw -p "Secret-Password" -s argon2 Fatal: Unknown scheme: ARGON2 I have tried different ways to enter "argon2", but nothing works. Can someone tell me what I am doing wrong? Thanks :) -- Jerry
