Disable SIS
by Nick Rosier 15 Mar '18

15 Mar '18

Hi, I'm currently running a small home-server with Dovecot. A long time ago I configured it with SIS enabled. I would like to stop using SIS. If I remove sis from mail_attachment_fs will the old mails that are stored in SIS-storage still be accessible? How can I convert all mailboxes to stop using SIS and store attachments back in the mails? Rgds, N.

Argon2i support in CE packages
by Grégory Oestreicher 14 Mar '18

14 Mar '18

Hi All, I've been experimenting with the Argon2i password scheme in a local setup, backed by a LDAP server, and Dovecot 2.3.0.1 can't authenticate my users for now. On the LDAP side the user passwords start with {ARGON2I} (and I can authenticate fine to the LDAP server), but it seems that the CE packages are compiled without libsodium. Is that correct? Is at this time the only alternative to recompile Dovecot myself, or are there plans to compile CE packages with libsodium? Cheers, Grégory

Virtual Mailboxes redux

13 Mar '18

I’ve created virtual mailboxes in dovecot, and they show up in various clients, but the folders contain no messages. (I will get an ‘empty” folder icon named “@virtual” and an empty folder icon named “month” inside it. Is there a way I can verify what dovecot THINKS should be in the virtual folder via doveadm? <https://www.dropbox.com/s/hd4wnjrs3y5iswi/Screenshot%202018-03-06%2011.38.2…> # cat /usr/local/etc/dovecot/virtual/month/dovecot-vitual # ~/Maildir/virtual/month/dovecot-virtual * all younger 2678400 # doveconf -n # 2.2.33.2 (d6601f4ec): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.21 (92477967) # OS: FreeBSD 11.1-RELEASE-p4 i386 auth_failure_delay = 5 secs auth_mechanisms = PLAIN LOGIN default_client_limit = 4096 default_process_limit = 1024 default_vsz_limit = 768 M disable_plaintext_auth = no first_valid_uid = 89 imap_id_log = * lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes login_log_format_elements = user=<%u> %r %m %c mail_location = maildir:~/Maildir mail_max_userip_connections = 90 mail_plugins = " virtual" managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext imapsieve vnd.dovecot.imapsieve namespace { location = virtual:/usr/local/etc/dovecot/virtual:INDEX=~/Maildir/virtual:CONTROL=~/Maildir/virtual prefix = @virtual. separator = . } namespace inbox { inbox = yes location = mailbox Archive { auto = subscribe special_use = \Archive } mailbox Drafts { special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam username_filter = !*@* } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Junk imapsieve_mailbox2_before = file:/usr/lib/dovecot/sieve/report-ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Junk imapsieve_mailbox2_name = * sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment sieve_pipe_bin_dir = /usr/lib/dovecot/sieve sieve_plugins = sieve_imapsieve sieve_extprograms } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </path/to/fullchain.pem ssl_key = # hidden, use -P to show it ssl_protocols = !SSLv2 !SSLv3 userdb { driver = passwd } userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=/usr/local/virtual/%u mail=maildir:/usr/local/virtual/%u driver = sql } protocol imap { mail_plugins = " virtual imap_sieve" }

Assertion during dsync receive
by Ian Bobbitt 13 Mar '18

13 Mar '18

Hi, I'm getting an assertion failed on the receiving side, causing syncs to fail for one user. The servers are setup so that only one is receiving any traffic other than replication at any time. The one that's only receiving replications is the one that's failing. I've tried deleting the user's home on the receiving server, but it still crashes during the sync. Oddly, the user's home is 7.4G on the sending server, but ends up at 42G on the receiving side, even after deleting and trying a fresh sync. The mailbox implicated in the backtrace ("Spam") does have a very large number of messages in it. On sender: Spam messages=1217764 recent=0 uidnext=1218103 uidvalidity=1379509105 unseen=16 highestmodseq=744588 vsize=34468460093 guid=090ed93a7a055559abf10200fdf6807a firstsaved=1498744186 On receiver: Spam messages=1217766 recent=352 uidnext=1218105 uidvalidity=1379509105 unseen=16 highestmodseq=744589 vsize=34468496809 guid=090ed93a7a055559abf10200fdf6807a firstsaved=1519396172 Feb 23 14:57:20 dovecot: dsync-local(bgeels): Warning: fscking index file /gnoc/mail/home/bgeels/mail/storage/dovecot.map.index Feb 23 14:57:20 dovecot: dsync-local(bgeels): Warning: mdbox /gnoc/mail/home/bgeels/mail/storage: rebuilding indexes Feb 23 14:57:33 dovecot: dsync-local(bgeels): Panic: file mail-index-util.c: line 10 (mail_index_uint32_to_offset): assertion failed: (offset < 0x40000000) Feb 23 14:57:33 dovecot: dsync-local(bgeels): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x9f3de) [0x7feb584143de] -> /usr/lib64/dovecot/libdovecot.so.0(+0x9f4be) [0x7feb584144be] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7feb583a577c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_uint32_to_offset+0xa0) [0x7feb587906d0] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_cache_compress+0x854) [0x7feb58774f34] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_sync_commit+0x25f) [0x7feb587884ff] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_storage_rebuild_in_context+0x10de) [0x7feb5870b3ae] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_sync_begin+0x858) [0x7feb5870ccd8] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_sync+0x4c) [0x7feb5870ce7c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_storage_sync_init+0x4b) [0x7feb5870cf3b] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x44) [0x7feb586f2834] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync+0x37) [0x7feb586f28d7] -> dovecot/doveadm-server(dsync_mailbox_import_deinit+0x475) [0x445495] -> dovecot/doveadm-server() [0x43edc0] -> dovecot/doveadm-server(dsync_brain_sync_mails+0x743) [0x43f653] -> dovecot/doveadm-server(dsync_brain_run+0x541) [0x43acf1] -> dovecot/doveadm-server() [0x43b070] -> dovecot/doveadm-server() [0x44fe5f] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7feb58429cd2] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x10f) [0x7feb5842b3bf] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x3c) [0x7feb58429d6c] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7feb58429f28] -> dovecot/doveadm-server() [0x4209c5] -> dovecot/doveadm-server() [0x422df6] -> dovecot/doveadm-server() [0x4377f4] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7feb58429cd2] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x10f) [0x7feb5842b3bf] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x3c) [0x7feb58429d6c] Feb 23 14:57:33 dsync-local(bgeels): Fatal: master: service(doveadm): child 82098 killed with signal 6 (core dumped) I've attached the output of `doveconf -n` and the full backtrace from a core dump.

Extra intermediate certificate when using ssl_alt_cert
by Peter Linss 13 Mar '18

13 Mar '18

I just added an ECDSA certificate to my mail server using ssl_alt_cert (the RSA certificate is specified by ssl_cert), both certificate files contain the certificate and a single intermediate (which currently happens to be the same intermediate from Let’s Encrypt). When connecting to the server using either RSA or ECDSA ciphers, the server sends the proper certificate, but also sends two intermediates. Apparently it’s reading the intermediate from both files and using both for all situations, rather than using only the intermediate in the RSA file for RSA certificates, and the intermediate in the ECDSA file for ECDSA certificates. I expect this will be a bigger problem when Let’s Encrypt starts using ECDSA intermediates. Removing the intermediate from the ssl_alt_cert file solves the problem (but then doesn’t allow an ECDSA intermediate to be specified).

2.2.34 broken if ssl_protocols contains !SSLv2
by Stuart Henderson 11 Mar '18

11 Mar '18

The code in ssl_protocols_to_min_protocol() to convert ssl_protocols to min/max values can't cope with strings containing "!SSLv2". dovecot: imap-login: Fatal: Unknown ssl_protocols setting: Unrecognized protocol 'SSLv2' This string might be configured explicitly by the user, or if the user hasn't configured this themselves it could also come from the default because master_service_ssl_default_settings sets this: #ifdef SSL_TXT_SSLV2 .ssl_protocols = "!SSLv2 !SSLv3", #else .ssl_protocols = "!SSLv3", #endif

Hello, I've got dovecot authenticating to a MySQL database. I've got a field varchar(128) called password. Whenever I create a password I use doveadm pw as in: doveadm pw -s sha512-crypt now i'd like to get MySQL to make a dovecot-specific password. My goal is to eventually have roundcube's password plugin working with this MySQL database to change the password. Thanks. Dave.
