pop3_migration plugin
by Andrea Gabellini 19 Aug '20

19 Aug '20

Hello, I'm trying to migrate from an old courier-IMAP server on which I made a plugin to access the individual mailboxes with a master password Emails are used in both POP3 and IMAP. I followed this guide https://wiki.dovecot.org/Migration/Dsync In the log I find these messages, which are generated by the server independently without issuing the command "doveadm backup ..." dsync-local (xxxxxxx) <yIAgHZtVPF85HwAA9osHUQ>: Error: pop3_migration: 8044 POP3 messages have no matching IMAP messages (first POP3 msg 1 UIDL UID33550-1353000352) - all IMAP messages were found (POP3 may contain more than IMAP to INBOX - you may want set pop3_migration_all_mailboxes = yes) - set pop3_migration_ignore_missing_uidls = yes or pop3_migration_ignore_extra_uidls = yes to continue anyway The mailboxes obviously have at least the "Sent", "Trash" and "Drafts" mailboxes. What should I do? Where can I find documentation of the pop3_migration plugin?

Sieve scripts replication not working
by Piotr Auksztulewicz 18 Aug '20

18 Aug '20

Hi all! I am a long-time dovecot user/admin on my home server, but only recently tried to configure replication. Everything seems to work except sieve scripts replication. When I upload new one on the server A, it does not replicate to server B, even if it seemingly tries to, according to debug logs. The log antry says: Replication requested by 'sieve_storage_sync_transaction_begin', priority=1 on server A, but nothing like that on server B. Server B logs show that server A is connecting to doveadm service but little else. Any ideas what could be wrong? Please see the logs below. Users and domains have been anonymized. ----- Upload ------------- $ sieve-connect -s serverA.mydomain.example -p sieve -u user(a)mydomain.example --notlsverify Sieve/IMAP Password: ReadLine support enabled. > put lists > put autosave ----- Server A log ------- Aug 18 16:05:49 serverA dovecot[60776]: managesieve-login: Login: user=<user(a)mydomain.example>, method=PLAIN, rip=<redacted>, lip=<redacted>, mpid=35651, TLS, session=<Qw4fYiet/uEKKCgK> Aug 18 16:05:49 serverA dovecot[60776]: managesieve(user(a)mydomain.example)<35651><Qw4fYiet/uEKKCgK>: Debug: Loading modules from directory: /usr/lib/dovecot/modules Aug 18 16:05:49 serverA dovecot[60776]: managesieve(user(a)mydomain.example)<35651><Qw4fYiet/uEKKCgK>: Debug: Module loaded: /usr/lib/dovecot/modules/lib15_notify_plugin.so Aug 18 16:05:49 serverA dovecot[60776]: managesieve(user(a)mydomain.example)<35651><Qw4fYiet/uEKKCgK>: Debug: Module loaded: /usr/lib/dovecot/modules/lib20_replication_plugin.so Aug 18 16:05:49 serverA dovecot[60776]: managesieve(user(a)mydomain.example)<35651><Qw4fYiet/uEKKCgK>: Debug: Effective uid=113, gid=122, home=/var/vmail/user(a)mydomain.example Aug 18 16:05:49 serverA dovecot[60776]: managesieve(user(a)mydomain.example)<35651><Qw4fYiet/uEKKCgK>: Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/mail:LAYOUT=fs:DIRNAME=.MailDir:UTF-8 Aug 18 16:05:49 serverA dovecot[60776]: managesieve(user(a)mydomain.example)<35651><Qw4fYiet/uEKKCgK>: Debug: fs: root=/var/vmail/user(a)mydomain.example/mail, index=, indexpvt=, control=, inbox=, alt= Aug 18 16:05:49 serverA dovecot[60776]: managesieve(user(a)mydomain.example)<35651><Qw4fYiet/uEKKCgK>: Debug: sieve: Pigeonhole version 0.5.4 () initializing Aug 18 16:05:49 serverA dovecot[60776]: managesieve(user(a)mydomain.example)<35651><Qw4fYiet/uEKKCgK>: Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts.

Getting this when attempting to build 2.3.11.3 on CentOS 6: test-mail-cache.c:176: Assert failed: strcmp(str_c(str),"123\nfoo\n456\nbar\n") "" != "123 foo 456 bar " test-mail-cache.c:176: Assert failed: strcmp(str_c(str),"123\nfoo\n456\nbar\n") "" != "123 foo 456 bar " mail cache uncommitted lookups ....................................... : FAILED Full make check output is at https://paste.centos.org/view/b48d38a9 I can provide full build logs if you want, but that's a 4M file so I'll provide it upon request. For now I'm going ot have to bypass the make check stage of the build for CentOS 6, but I worry that the failed check could be indicative of something critical. Peter

Apple Mail Since upgrade to dovecot 2.3.x unable to connect

|Dear all,| |a couple of days ago I upgraded our server from Ubuntu 18.04 to 20.04, thereby upgrading dovecot from 2.2.x to 2.3.x. | |Since then, some older versions of apple's mail.app (bundled with el Capitano, released in 2016) no longer connect.

MDBOX DSYNC error: Broken physical size in mailbox
by paul-dovecotlist＠trainor.nz 18 Aug '20

18 Aug '20

Hi All, I currently have a small Dovecot server (Server A) and I've installed a second dovecot mailbox server (server B) and am trying to sync mailboxes from Server A to Server B. Both servers sit behind two dovecot directors on separate hosts and have identical config files (doveconf -n output below). Mailboxes on Server A are on an NFS mount. Server A has been working fine with no issues for a couple of years. I'm running this command on Server A: doveadm sync -u #user# tcp:#newservername#:24245 Small mailboxes with few items are syncing OK.. but most mailboxes fail (sycn stops) with the following type of error: (Mailbox name, storage file, UID and sizes vary). dsync-local(#username#)<b2vTDKerOV/fAQAAZMK/0g>: Error: Mailbox INBOX: Cache /#usershomedirectory#/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: Deleting corrupted cache record uid=9: UID 9: Broken physical size in mailbox INBOX: read(/#usershomedirectory#/mdbox/storage/m.1) failed: Cached message size larger than expected (60616 > 8688, box=INBOX, UID=9) If I run it again, I'll get the same error, but with a new UID. If I do a local migration instead of server to server, I still get the errors. e.g. doveadm sync -u #user# maildir:~/Maildir-test/ I tried running a force resync (doveadm force-resync -u #user# -f "*) but it didn't help. There's no issues from an imap client accessing any emails. Using imapsync to sync affected mailboxes works fine for example. But... if I then run a dsync on Server B (doveadm sync -u #user# maildir:~/Maildir-test/) on an account that was successfully migrated with imapsync, I get the issue again. How worried should I be about these corrupted cache records, and any ideas how to resolve? Thanks in advance for your help!

Apple Mail Since upgrade to dovecot 2.3.x unable to connect
by Johannes Rohr 17 Aug '20

|Dear all,| |a couple of days ago I upgraded our server from Ubuntu 18.04 to 20.04, thereby upgrading dovecot from 2.2.x to 2.3.x. | |Since then, some older versions of apple's mail.app (bundled with el Capitano, released in 2016) no longer connect. When I turn on SSL debugging, I see:| |Debug: SSL error: SSL_accept() failed: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol imap-login: Debug: SSL error: SSL_accept() syscall failed: Invalid argument| || |Unfortunately, it doesn't reveal the name of the unsupported protocol. Also, what about the failed syscall? Does dovecot try and fail to open some file?| |Here are the contents of /etc/dovecot/conf.d/10-ssl.conf:| | ssl = yes ssl_cert = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/fullchain.pem ssl_key = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/key.pem ssl_ca = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/ca.pem ssl_client_ca_dir = /etc/ssl/certs ssl_dh = </etc/dovecot/dh.pem | |I would greatly appreciate any hints! | |Cheers,| |Johannes | | | ||

generating secure ARGON2ID passwords
by Felix Zielcke 16 Aug '20

16 Aug '20

Hello, I'm using dovecot 2.3.4.1 on a Debian buster system. with Argon2ID password scheme, it's only possible to configure the parameters used for it via the generic -r option to "doveadm pw". A higher -r will increase time and memory comsumption. But on my dual core VM it always uses p=1. So it seems the needed threads can only be changed on compile time? Will there be in future a way to explicitly specify memory, time and threads needed for Argon2ID?
