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.

mail_attachment_detection_options not working
by Alessio Cecchi 09 Mar '18

09 Mar '18

Hi, I enabled mail_attachment_detection_options on dovecot 2.2.34, in 10-mail.conf I have: mail_attachment_detection_options = add-flags-on-save but when an email is delivered in mailbox (Maildir) via LMTP no flag (HasNoAttachment or HasAttachment) was added. In dovecot-keywords file I have: 0 $HasNoAttachment 1 NonJunk 2 $HasAttachment so I thinks that the feature was eanbled but is unable. What am I doing wrong? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

I'm running Dovecot 2.2.27 (c0f36b0) on Debian Stretch and I'm having some trouble with LMTP delivery from Postfix to Dovecot. The message in the logs is Mar 9 09:21:19 mail postfix/smtpd[3295]: NOQUEUE: reject: RCPT from some.mail.server[1.2.3.4]: 450 4.1.1 <alias(a)my.domain>: Recipient address rejected: unverified address: host my.mail.server[private/dovecot-lmtp] said: 550 5.1.1 <user(a)my.domain> User doesn't exist: user(a)my.domain (in reply to RCPT TO command); from=<someone(a)another.domain> to=<alias(a)my.domain> proto=ESMTP helo=<some.mail.server> However, testing my installation with doveadm works fine: doveadm user -u user(a)my.domain userdb: user(a)my.domain user : user(a)my.domain uid : 5000 gid : 5000 home : /srv/mail/vhosts/my.domain/user doveadm auth test user(a)my.domain passdb: user(a)my.domain auth succeeded I'm using a static userdb and a ldap passdb: # /etc/dovecot/conf.d/auth-ldap.conf.ext passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/srv/mail/vhosts/%d/%n } And my LDAP config reads like this # /etc/dovecot/dovecot-ldap.conf.ext uris = ldap://127.0.0.1 dn = uid=dovecot,ou=services,dc=my,dc=domain dnpass = ********* auth_bind = yes auth_bind_userdn = cn=%u,ou=mail,dc=my,dc=domain ldap_version = 3 base = ou=mail,dc=querco,dc=org deref = never scope = onelevel user_attrs = user_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)(cn=%u)) pass_attrs = cn=user,userPassword=password pass_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)(cn=%u)) iterate_attrs = cn=user iterate_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)) Sending the mail straight to user(a)my.domain works. Sending it to another alias works as well. Is there some caching problem and if so how to delete the cache (reboot didn't work)? Any pointers are highly appreciated.
