Since http://dovecot.org/pipermail/dovecot-cvs/2014-November/025241.html Dovecot's LMTP does support ORCPT. Is it possible to set X-Original-To-Header based on that ORCPT?

dovecot Panic: file mail-index-sync-update.c: line 1013
by Eugen I 08 Aug '18

08 Aug '18

An email came to several users but one user didn't receive it and we got 'Mail delivery failed' message. As I see from the log below, there were broken index file. Then dovecot repaired that index and we got the error: Panic: file mail-index-sync-update.c: line 1013 (mail_index_sync_map): assertion failed: (map->hdr.indexid == index->indexid || map->hdr.indexid == 0) It was one-time error and it has not reappeared yet. At the moment the user receives emails successfully (in .Queue.… [View More]A_Sup.group_05 as well). It is supposed that Dovecot had to repair index file and put the email in mnt/mail//user05/Maildir/.Queue.A_Sup.group_05/ directory but it didn't. Is there something wrong with Dovecot? Thanks. --- Operating system: Linux Centos 7 3.10.0-862.3.2.el7.x86_64 #1 SMP Mon May 21 23:36:36 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux rpm -qa |grep dovecot dovecot-pigeonhole-2.2.10-8.el7.x86_64 dovecot-2.2.10-8.el7.x86_64 dovecot.log output --------------------- Aug 06 23:19:24 lda: Debug: Loading modules from directory: /usr/lib64/dovecot Aug 06 23:19:24 lda: Debug: Module loaded: /usr/lib64/dovecot/lib90_sieve_plugin.so Aug 06 23:19:24 lda(user05): Debug: Effective uid=10492, gid=10001, home=/mnt/mail/user05 Aug 06 23:19:24 lda(user05): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/mnt/mail//user05/Maildir:INBOX=/mnt/mail//user05/Maildir Aug 06 23:19:24 lda(user05): Debug: maildir++: root=/mnt/mail//user05/Maildir, index=, indexpvt=, control=, inbox=/mnt/mail//user05/Maildir, alt= Aug 06 23:19:24 lda(user05): Debug: userdb lookup skipped, username taken from USER environment Aug 06 23:19:24 lda(user05): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= Aug 06 23:19:24 lda(user05): Debug: Destination address: user05(a)imap.po.com (source: user@hostname) Aug 06 23:19:24 lda(user05): Debug: sieve: Pigeonhole version 0.4.2 initializing Aug 06 23:19:24 lda(user05): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts.

Reproducible SIGSEGV when Dovecot 2.3 compiled against glibc-2.28
by Reuben Farrelly 08 Aug '18

Hi, Dovecot 2.3 (release and current -git) versions compile, but fail to run when compiled against glibc-2.28. This is what is logged on startup: Aug 8 08:24:39 thunderstorm.reub.net dovecot[569]: master: Dovecot v2.3.2.1 (0719df592) starting up for imap, lmtp, sieve, submission, sieve Aug 8 08:24:39 thunderstorm.reub.net dovecot[569]: master: Error: service(auth): command startup failed, throttling for 2 secs Aug 8 08:24:39 thunderstorm.reub.net dovecot[574]: auth: Fatal: master: … [View More]service(auth): child 582 killed with signal 11 (core dumped) Aug 8 08:24:39 thunderstorm.reub.net dovecot[574]: replicator: Error: userdb lookup: Disconnected unexpectedly Aug 8 08:24:52 thunderstorm.reub.net dovecot[569]: master: Warning: Killed with signal 15 (by pid=670 uid=0 code=kill) The issue is specifically with the 'auth' binary. Other components all appear to be unaffected. The 'auth' binary dies with a Segmentation Fault when run as a standalone executable too.

dsync not replicating ".dovecot.sieve -> .sieve/managesieve.sieve"
by Tony 06 Aug '18

06 Aug '18

Hi, Currently using dovecot 2.3.2.1 and pigeonhole 0.5.2 on two identical hosts. I recently noticed ".dovecot.sieve" and ".sieve/managesieve.sieve" are not replicating from one host to the other in either direction. Mail is having no trouble replicating on both hosts with dsync, it is only sieve files that are not replicating for unclear reasons. # doveconf -n host 1: https://ptpb.pw/njs3 host 2: https://ptpb.pw/KsfK If I enable sieve debug logs I don't see anything that would cause … [View More]alarm. The error logs are also not reporting any trouble. I have tested creating filters in Roundcube which is hosted from host1. This creates the sieve files as expected, but the same sieve files do not replicate to host2. When using Sieve with Thunderbird if the sieve files are created on host1 or host2, these are not replicating with dsync. So it does not seem to matter if the sieve files are created on either host and with any mail client, they just do not replicate at all. # host1 stat /home/vmail/example.email/user\(a)example.email/.dovecot.sieve File: /home/vmail/example.email/user(a)example.email/.dovecot.sieve -> .sieve/managesieve.sieve Size: 24 Blocks: 0 IO Block: 4096 symbolic link Device: 800h/2048d Inode: 596605 Links: 1 Access: (0777/lrwxrwxrwx) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2018-08-05 15:24:41.351827516 -0700 Modify: 2018-08-05 15:24:41.351827516 -0700 Change: 2018-08-05 15:24:41.351827516 -0700 Birth: - stat /home/vmail/example.email/user\(a)example.email/.sieve/managesieve.sieve File: /home/vmail/example.email/user(a)example.email/.sieve/managesieve.sieve Size: 65 Blocks: 8 IO Block: 4096 regular file Device: 800h/2048d Inode: 1657978 Links: 1 Access: (0600/-rw-------) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2018-08-05 15:27:30.034984088 -0700 Modify: 2018-08-05 15:27:30.034984088 -0700 Change: 2018-08-05 15:27:30.034984088 -0700 Birth: - # host2 stat /home/vmail/example.email/user\(a)example.email/.dovecot.sieve File: /home/vmail/example.email/user(a)example.email/.dovecot.sieve -> .sieve/managesieve.sieve Size: 24 Blocks: 0 IO Block: 4096 symbolic link Device: fe03h/65027d Inode: 787482 Links: 1 Access: (0777/lrwxrwxrwx) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2018-08-05 16:10:54.832151815 -0700 Modify: 2018-08-05 16:10:54.815484905 -0700 Change: 2018-08-05 16:10:54.815484905 -0700 Birth: - stat /home/vmail/example.email/user\(a)example.email/.sieve/managesieve.sieve File: /home/vmail/example.email/user(a)example.email/.sieve/managesieve.sieve Size: 18 Blocks: 8 IO Block: 4096 regular file Device: fe03h/65027d Inode: 786938 Links: 1 Access: (0600/-rw-------) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2018-08-05 16:10:54.815484905 -0700 Modify: 2018-08-05 16:10:49.818745528 -0700 Change: 2018-08-05 16:10:49.822078910 -0700 Birth: - Here is the Maildir tree view. tree -a /home/vmail/example.email/user\(a)example.email/ /home/vmail/example.email/user(a)example.email/ ├── .dovecot.sieve -> .sieve/managesieve.sieve ├── Maildir │ ├── .Archive │ │ ├── cur │ │ ├── dovecot.index.log │ │ ├── dovecot-uidlist │ │ ├── maildirfolder │ │ ├── new │ │ └── tmp │ ├── cur │ │ ├── 1531611877.M860311P418538.mail,S=5999,W=6167:2,RS │ │ ├── 1531624146.M201381P535494.mail,S=2133,W=2184:2,S │ │ ├── 1533194577.M483202P864896.mail,S=6117,W=6393:2,S │ │ └── 1533195582.M123163P877084.mail,S=1739,W=1786:2,S │ ├── dovecot.index │ ├── dovecot.index.cache │ ├── dovecot.index.log │ ├── dovecot-keywords │ ├── dovecot.list.index │ ├── dovecot.list.index.log │ ├── dovecot.mailbox.log │ ├── dovecot-uidlist │ ├── dovecot-uidvalidity │ ├── dovecot-uidvalidity.5b4a79b5 │ ├── .Drafts │ │ ├── cur │ │ ├── dovecot.index.log │ │ ├── dovecot-uidlist │ │ ├── maildirfolder │ │ ├── new │ │ └── tmp │ ├── maildirsize │ ├── new │ ├── .Sent │ │ ├── cur │ │ │ ├── 1531611855.M403833P418688.mail,S=3510,W=3623:2,S │ │ │ └── 1531624037.M238133P535494.mail,S=436,W=451:2,S │ │ ├── dovecot.index.cache │ │ ├── dovecot.index.log │ │ ├── dovecot-uidlist │ │ ├── maildirfolder │ │ ├── new │ │ └── tmp │ ├── .Sent Messages │ │ ├── cur │ │ ├── dovecot.index.log │ │ ├── dovecot-uidlist │ │ ├── maildirfolder │ │ ├── new │ │ └── tmp │ ├── .Spam │ │ ├── cur │ │ ├── dovecot.index.cache │ │ ├── dovecot.index.log │ │ ├── dovecot-uidlist │ │ ├── maildirfolder │ │ ├── new │ │ └── tmp │ ├── subscriptions │ ├── tmp │ └── .Trash │ ├── cur │ ├── dovecot.index.cache │ ├── dovecot.index.log │ ├── dovecot-uidlist │ ├── maildirfolder │ ├── new │ └── tmp └── .sieve ├── managesieve.sieve └── tmp 30 directories, 41 files I know at one point sieve files must have been replicating with dsync, it's just not clear to me at which version of dovecot and pigeonhole this began with the exception of mail files which are replicating.

Assertion failure with IMAP NOTIFY
by Florian Pritz 05 Aug '18

05 Aug '18

Hi, For a few weeks I've been running a custom notification script[1] that uses IMAP NOTIFY. The script uses a single connection, sets up a NOTIFY watch on a couple of mailboxes + automatic FETCH for the selected mailbox. If a status update arrives for a different mailbox, it selects that box and fetches the mail.
