MailCrypt: Encrypted user keys configuration with LDAP & cryptokey generate
by FELINN 28 Mar '19

28 Mar '19

Hi, I try to use the MailCrypt plugin with Floder encryption and encrypted user keys, using LDAP. I use Dovecot 2.2.27 (c0f36b0) I follow the wiki: https://wiki2.dovecot.org/Plugins/MailCrypt doveconf -n and dovecot-ldap.conf.ext attached to this message. I well configured slapd to let dovecot's dn query the userPassword (hashed password SSHA). I use fusiondirectory-mail plugin: ------------------------------------------------------------------------ $ ldapsearch -D 'cn=dovecot,ou=dsa,dc=foo,dc=bar' -W -LLL '(&(objectClass=gosaMailAccount)(objectClass=posixAccount)(uid=<user>))' 'userPassword' dn: cn=<user>,ou=people,dc=foo,dc=bar userPassword:: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX ------------------------------------------------------------------------ The problem is that mails still readable and no keys are generated, even if a send a mail to this address, or login through webmail. I wait more than 1h until something happens, Cf: https://dovecot.org/list/dovecot/2018-September/112763.html If I try to generate keys manually I get this error: ------------------------------------------------------------------------ $ doeveadm mailbox cryptokey generate -u <user> doveadm(<user>): Error: mail_crypt_user_generate_keypair(<user>) failed: mail_crypt_require_encrypted_user_key set, cannot generate user keypair without password or key Folder Public ID x ERROR: mail_crypt_require_encrypted_user_key set, cannot generate user keypair without password or key doveadm(<user>): Warning: Timeout leak: 0x7f0c439c0180 (mail-index-alloc-cache.c:240) ------------------------------------------------------------------------ It works with -o plugin/mail_crypt_private_password=<password> of course, but by hand it's not the goal >< I probably miss something, I guess that the part of the wiki about sql and password_query is only for configuration that use SQL for dbuser. Is there similar things to do with LDAP? Thank you very much for your time. -- f00wl FELINN https://felinn.org

Weird things in the mail queue
by Lionel Elie Mamane 27 Mar '19

27 Mar '19

I noticed a mail stuck in my mail queue. dovecot-lda was returning error 64 Invalid parameter given. (EX_USAGE). Weird, weird, weird. After some sleuthing, I found the sender address was FirstLast(a)domain.tld, with a UTF8-encoded Unicode U+FEFF ZERO WIDTH NO-BREAK SPACE character (AKA byte order mark) between "First" and "Last" :) Since that is passed as the -f parameter to dovecot-lda, it was giving the 64 error.

Maildir permissions issue with Postfix
by Randall R. Sargent 27 Mar '19

27 Mar '19

Hi all, We have a Postfix server that serves as an alias MTA to route to other mail systems. I've recently installed Dovecot on it because we have three service accounts that need simple POP3 mailboxes. I have the accounts set up on the system and mail does get delivered to their ~/Maildir/ locations by Postfix, however, every time a message is dropped in the Maildir for the user, the permissions for the message are set to the user's uid:gid and Dovecot can't access the mail message. Doing a chmod fixes it temporarily until the next message drops. The vmail group has access to the user's home folder structure. Any help is appreciated!! Dovecot: 2.2.36 /etc/dovecot/dovecot.conf: auth_debug = yes disable_plaintext_auth = no first_valid_uid = 1002 log_path = /var/log/dovecot.log mail_debug = yes mail_home = /srv/mail/%Lu mail_location = maildir:~/Maildir mbox_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = / } passdb { driver = pam } service auth-worker { user = root } userdb { args = blocking=no driver = passwd override_fields = uid=vmail gid=vmail } Thanks, Randy

doveadm backup doesn't transfer mail from root INBOX
by Francis 27 Mar '19

27 Mar '19

Hi, I'm trying to migrate IMAP mails from dovecot 1.1.20apple0.5 (osx) to dovecot 2.2.33.2 (ubuntu). I'm using "doveadm backup" to migrate my data. It works fine for all subfolders, but the root INBOX stay empty on the new server. I suspect a problem related with hierarchy separator ("." on previous server, "/" on new) or with the namespace prefix (set to "INBOX/" on new server). Any hint? Thanks. show there is no messages in INBOX # doveadm mailbox status -u (myuser) all INBOX INBOX messages=0 recent=0 uidnext=1 uidvalidity=1553630060 unseen=0 highestmodseq=1 vsize=0 guid=d54cd42849739b5cb5790000ed87e144 firstsaved=18446744073709551615 show there is messages in subdirectory #

index problems after update
by Hajo Locke 27 Mar '19

27 Mar '19

Hello List, i have a problem with index-files which is separated in 2 subproblems. May be these problems are connected. Currently we use Ubuntu 18.04 LTS which is bundled with dovecot 2.2.33.2 These servers are fresh installed machines and users are added to the system after, there was no upgrade. Sometimes it happens, that dovecot stops showing new mail. There is no error in log, dovecot just seems to do his normal operations but is not delivering new emails from /var/mail/myuser emails are delivered again if i delete index-files from .imap folder. So index is recreated and everything works again. I cant reproduce this problem, but every 2 days i have one user who is reporting this problem. Second problem is similiar. I Upgraded a server from Ubuntu 16.04 to Ubuntu 18.04. This includes an upgrade from dovecot 2.2.22 to 2.2.33.2. After that i installed an self packaged dovecot 2.2.36.1 Now here is same problem, dovecot is not showing new mails, but the difference is we have a Raw backtrace in Log just as expected: Feb 8 08:45:37 hostname dovecot[14882]: imap(myuser): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0xa1ee2) [0x7f78b3b2cee2] -> /usr/lib/dovecot/libdovecot.so.0(+0xa1fda) [0x7f78b3b2cfda] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f78b3abb8a8] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_mail_parse_header+0x78a) [0x7f78b3e7940a] -> /usr/lib/dovecot/libdovecot.so.0(+0x83592) [0x7f78b3b0e592] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x74) [0x7f78b3b38814] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read_data+0x3d) [0x7f78b3b392fd] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_mail_get_header_stream+0x4a) [0x7f78b3e7a2ea] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_get_header_stream+0x4a) [0x7f78b3dfd8da] -> /usr/lib/dovecot/libdovecot-storage.so.0(imap_msgpart_open+0x24a) [0x7f78b3ebb57a] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](+0x2081c) [0x5581ac76d81c] -> dovecot/imap [m038422 ip.ip.ip.ip FETCH](+0x1ea54) [0x5581ac76ba54] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](imap_fetch_more+0x39) [0x5581ac76cd69] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](cmd_fetch+0x31b) [0x5581ac75e1bb] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](command_exec+0x5c) [0x5581ac76a09c] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](+0x1b612) [0x5581ac768612] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](+0x1b6ac) [0x5581ac7686ac] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](client_handle_input+0x18d) [0x5581ac768a6d] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](client_input+0xac) [0x5581ac768fbc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7f78b3b43482] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x12e) [0x7f78b3b44b9e] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x36) [0x7f78b3b43516] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f78b3b436c8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f78b3ac6aa3] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](main+0x329) [0x5581ac75b159] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xe7) [0x7f78b36bbb97] -> dovecot/imap [myuser ip.ip.ip.ip FETCH](_start+0x2a) [0x5581ac75b2fa] Feb 8 08:45:37 hostname dovecot[14882]: imap(myuser): Fatal: master: service(imap): child 14135 killed with signal 6 (core dumped) Over all dovecot and OS versions we use same old-fashioned setup.

Test SASL authentication via telnet (or similar)
by Alessio Cecchi 26 Mar '19

26 Mar '19

Hi, I'm looking for a way to autenticate my email users via Dovecot SASL TCP connections from an external nodejs or python script. Dovecot configuration is fine, if I set in postfix smtpd_sasl_path = inet:127.0.0.1:12345 works fine. But if a try via "telnet 127.0.0.1 12345" to chat with SASL in dovecot log found: dovecot: auth: Error: Authentication client not compatible with this server (mixed old and new binaries?) What is the right way to chat with SASL via TCP port? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

dovecot 2.3.5 - tests fail: http payload echo (ssl)
by Helmut K. C. Tessarek 26 Mar '19

26 Mar '19

Hi, I was womdering, if anyone has experienced the same issues. When I run the tests after compiling 2.3.5, the following 4 tests fail: http payload echo (ssl): sequential .................................. : ok http payload echo (ssl): pipeline .................................... : ok http payload echo (ssl): parallel .................................... : FAILED: Test is hanging http payload echo (ssl) .............................................. : FAILED http payload echo (ssl; unknown size): sequential .................... : ok http payload echo (ssl; unknown size): pipeline ...................... : ok http payload echo (ssl; unknown size): parallel ...................... : FAILED: Test is hanging http payload echo (ssl; unknown size) ................................ : FAILED 4 / 114 tests failed Failed to run: ./test-http-payload The tests ran fine for 2.3.4.1. Is there any way, to debug the issue any further? Do the tests write log files? It just doesn't make amy sense. Nothing has changed on the OS since I compiled and tested 2.3.4.1. Cheers, K. C. -- regards Helmut K. C.

imapsieve: script not triggered
by Andreas Krischer 25 Mar '19

25 Mar '19

Hi, folks! My problem: I set up dovecot with imapsieve to execute a script whenever a user copies a mail to his Spam folder (spam autolearning). Unfortunately this script is never executed regardless what I’m configuring for imapsieve. It looks like dovecot doesn’t really load the plugin… The "dovecot -n" output is attached. I already tried setting imapsieve_mailbox1_name to *, but even this does not execute the script… Also I tried a mailbox without mail_crypt enabled, no success as well. In the attached mail.log (mail_debug=yes) you can see, that imap_sieve_plugin is loaded, but it isn’t really executed. The normal (LMTP) sieve is working - if a mail is incoming the sieve module shows it work in mail.log: May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: file storage: Storage path `/var/vmail/myhost.name/postmaster/sieve' not found May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: file storage: Storage path `/var/vmail/myhost.name/postmaster/.dovecot.sieve' not found May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: storage: No default script location configured May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: User has no personal script May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: file storage: Using script storage path: /etc/dovecot/sieve/after/ May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: file script: Opened script `spam' from `/etc/dovecot/sieve/after/spam.sieve' May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: executed after user's Sieve script(1): /etc/dovecot/sieve/after/spam.sieve May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: Mailbox <lmtp DATA>: Opened mail UID=1 because: header Message-ID (Cache file is unusable) May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: Opening script 1 of 1 from `/etc/dovecot/sieve/after/spam.sieve' May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: Loading script /etc/dovecot/sieve/after/spam.sieve May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: Script binary /etc/dovecot/sieve/after/spam.svbin successfully loaded May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: binary save: not saving binary /etc/dovecot/sieve/after/spam.svbin, because it is already stored May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: Executing script from `/etc/dovecot/sieve/after/spam.svbin' I already spent hours on this problem so please let me know if you have any idea what the problem could be… :( Thanks in advance!
