oath-toolkit pam authentication with dovecot
by "Tóth Attila" 04 Apr '26

04 Apr '26

Anybody has experience in deploying oath-toolkit totp authentication for dovecot? It works for ssh in a challenge response fashion, but I have concernes against concatenating the password with the totp digits, because I have difficulties even with su+oath_toolkit... Thx: Dw. -- dr Tóth Attila, Radiológus, 06-20-825-8057 Attila Toth MD, Radiologist, +36-20-825-8057

Bug report: filter `default` in LDAP context does not suppress error logging
by Johannes Nohl 04 Apr '26

04 Apr '26

Bug report: Expanding variables with filter `default` in LDAP context does not suppress error logging if LDAP attribute is missing. Expected behaviour: Missing LDAP attribute does not throw an error. Example `nologin = %{ldap:missingAttribute | default}` Details: Please note: The missing attribute is called `shadowInactive` in reality. There might be another issue, the field nologin is boolean and set true if any value is assigned -- while default without parameter returns empty (thus, you cannot use default with nologin without workaround). The intended behaviour is documented clearly, however due to a bug in rendering you need to look into the doc sources (my PR for that was accepted already: https://doc.dovecot.org/2.4.2/core/config/auth/databases/ldap.html#ldap-spe… https://github.com/dovecot/documentation/pull/1478#pullrequestreview-403461… Full context: passdb ldap { driver = ldap ldap_filter = (&(objectClass=posixAccount)(mail=%{user})) fields { user = %{ldap:uid} nologin = %{ldap:shadowInactive | default} reason = The account for this email address is disabled. } } The same error was reported already a year ago, although among others, see point 4: https://dovecot.org/mailman3/archives/list/dovecot@dovecot.org/thread/TLJ2O… Please excuse my first attempt of 31-03-2026. It was unreadable. Aki already tried to help but was - I guess - distracted from the main point. I found a workaround for the missing attribute translation to boolean fields (if someone is interested) https://dovecot.org/mailman3/archives/list/dovecot@dovecot.org/thread/67Z4C… I tested with dovecot 2.4.2 and 2.4.3 (openSUSE repos) against local LDAP. The check for disabled users throws permanently errors in the log file, whenever the user is missing the ldap attribute for disabled. Thus, for each login of all enabled users (you will probably agree that this not acceptable). This results in the following log line: 2026-03-31T00:46:31.102690+02:00 mailserver dovecot: auth(test,ipv4,sasl:plain)<YE81n0VOVuofEeSD>: Error: ldap: auth_passdb_post settings: Failed to parse configuration: Failed to expand passdb_fields/nologin setting variables: ldap: No such attribute 'shadowinactive' Thank you Johannes -- Johannes Nohl postmaster(a)i-t-cloud.de

2.4 upgrade : INBOX does not exist
by Stefan G. Weichinger 02 Apr '26

02 Apr '26

Today I upgraded a server at a customer. I modified the config I had built over the last week, with the help of this list. So far nearly everything works, but thunderbird complains about non-existing mailboxes like INBOX. But we can access it, it's a bit strange. In the filesystem it looks like: # ls -la /home/vmail/our.tld/user\(a)our.tld/ insgesamt 7096 drwx------ 69 vmail vmail 4096 2. Apr 19:00 . drwx------ 129 vmail vmail 12288 2.

Error: sieve: fail2ban: line 23: read(<lmtp DATA local>) failed: Seeking past EOF by 2364 bytes
by Graham Cobb 01 Apr '26

01 Apr '26

Hi, dovecot is crashing for me while doing sieve processing for messages received via lmtp. This is reproducible, and seems to hit every message which runs a particular sieve script. Any thoughts or help would be appreciated! The error is: Error: sieve: fail2ban: line 23: read(<lmtp DATA local>) failed: Seeking past EOF by 2364 bytes Note: the number of bytes is always one of: 2169, 2272, 2259, 2364. I have many of these. I cannot see how the "Seeking past EOF" error can be caused by a bug in my sieve script. But please let me know if it can! Background: I have (and have had for many years) a complex set of sieve scripts for controlling my incoming email. They have worked fine for all that time. However, recently (ish), processing which uses a particular script is crashing dovecot. The actual log extract is below. The sieve script line 23, mentioned in the error report, is a large "if anyof (" statement containing many clauses like: body :raw :regex "country:[[:space:]]+KR", I can provide the full sieve script if required. This is what I see in the dovecot log (note: I reformatted the backtrace to make it easier to read. I also changed all my server names): Mar 29 03:03:52 SERVER dovecot-HOST: lmtp(4008073): Connect from local Mar 29 03:03:52 SERVER dovecot-HOST: lmtp(cobb)<4008073><PiAQHoiIyGmJKD0Ay7SJiA>: Error: sieve: fail2ban: line 23: read(<lmtp DATA local>) failed: Seeking past EOF by 2364 bytes Mar 29 03:03:52 SERVER dovecot-HOST: lmtp(cobb)<4008073><PiAQHoiIyGmJKD0Ay7SJiA>: Error: sieve: Execution of script 'auto:personal/.dovecot' was aborted due to temporary failure (user logfile /home/cobb/.dovecot.sieve.log may reveal additional details) Mar 29 03:03:52 SERVER dovecot-HOST: lmtp(cobb)<4008073><PiAQHoiIyGmJKD0Ay7SJiA>: Panic: file istream-concat.c: line 27 (i_stream_concat_close): assertion failed: (cstream->cur_input == cstream->input[cstream->cur_idx]) Mar 29 03:03:52 SERVER dovecot-HOST: lmtp(cobb)<4008073><PiAQHoiIyGmJKD0Ay7SJiA>: Error: Raw backtrace: #1 [unw_get_proc_name() failed: -10] -> #2 [unw_get_proc_name() failed: -10] -> #3 i_panic[0x7f41540655e6] -> #4 [unw_get_proc_name() failed: -10] -> #5 io_stream_unref[0x7f415413c120] -> #6 i_stream_unref[0x7f4154145c30] -> #7 index_storage_mailbox_close[0x7f4154383e70] -> #8 mailbox_close[0x7f41542fd9e0] -> #9 mailbox_free[0x7f4154302ab0] -> #10 lmtp_local_deinit[0x55dfa9c4e320] -> #11 client_state_reset[0x55dfa9c4f0d0] -> #12 smtp_server_transaction_free[0x7f4154091880] -> #13 smtp_server_connection_reset_state[0x7f4154093c90] -> #14 smtp_server_command_call_hooks[0x7f415408be60] -> #15 smtp_server_command_send_replies[0x7f4154090050] -> #16 [unw_get_proc_name() failed: -10] -> #17 [unw_get_proc_name() failed: -10] -> #18 io_loop_call_io[0x7f4154151710] -> #19 io_loop_handler_run_internal[0x7f41541534b0] -> #20 io_loop_handler_run[0x7f4154153640] -> #21 io_loop_run[0x7f4154153820] -> #22 master_service_run[0x7f41540a6330] -> #23 main[0x55dfa9c4a260] -> #24 __libc_start_call_main[0x7f4153e32c30] -> #25 __libc_start_main_alias_2[0x7f4153e32ce0] -> #26 _start[0x55dfa9c4a470] Mar 29 03:03:54 SERVER dovecot-HOST: lmtp(cobb)<4008073><PiAQHoiIyGmJKD0Ay7SJiA>: Fatal: master: service(lmtp): child 4008073 killed with signal 6 (core dumped) Mar 29 03:04:05 SERVER postfix/lmtp[4008072]: 005083DC75D: to=<MYADDRESS@MYDOMAIN>, orig_to=<ANOTHER@ANOTHERDOMAIN>, relay=SERVERNAME[private/dovecot-lmtp], delay=1740676, delays=1740674/0.25/0.04/1.5, dsn=4.4.2, status=deferred (lost connection with SERVERNAME[private/dovecot-lmtp] while sending end of data -- message may be sent more than once) The only message in .dovecot.sieve.log is: fail2ban: line 23: error: failed to read input message: internal error occurred: refer to server log for more information.
