Struggling to get sieve running
by nick＠howitts.co.uk 23 Oct '24

23 Oct '24

Hi, I am new to Dovecot and Debian, but I seem to have got Dovecot up and running with local delivery and then switched to LMTP. I am running Debian 12.7 and Webmin 2.202 to try and get things running, but I've had to tweak files. Also Webmin did not install dovecot-lmtpd, dovecot-sieve or dovecot-managesieved, so I did that manually. I have tried following the configuration guide from Dovecot (but there seems to be little there) and other sources I've found on the internet, but there is nothing I have found to get sieve listening on port 4190 when checked with ss. My Dovecot config from `dovecot -n` is: ``` # 2.3.19.1 (9b53102964): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.19 (4eae2f79) # OS: Linux 6.1.0-26-amd64 x86_64 Debian 12.7 # Hostname: my.fqdn auth_username_format = %Ln disable_plaintext_auth = no first_valid_uid = 1000 mail_location = maildir:~/Maildir mail_privileged_group = mail 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 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = imap lmtp service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/letsencrypt/live/mydomain.com/fullchain.pem ssl_client_ca_dir = /etc/ssl/certs ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } protocol lmtp { mail_plugins = " sieve" postmaster_address = nick(a)mydomain.com } protocol lda { mail_plugins = " sieve" } ``` Dovecot packages installed from the Debian repos are: ``` dovecot-core/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-imapd/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-lmtpd/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-managesieved/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-pop3d/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-sieve/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] ``` Ultimately I intend to run manage sieve from Roundcube which I have already got running, or I may try a Thunderbird addon. Can anyone give me some pointers, please?

Missing IMAP folders after upgrading from 2.3.17 to 2.3.21.1
by Frank Kirschner 23 Oct '24

23 Oct '24

Hi, I have upgraded from 2.3.17 to 2.3.21.1. mail_location = maildir Now in some mailboxes are IMAP folder in subdir of INBOX missing. When I do a 'ls -la' in filesystem, I see the subfolder like other folder with identical owner an permissions. But when I do doveadm mailbox list -u [user] the IMAP folder is not displayed. So I have deleted all files in /opt/dovecot/[hash]/[user] because I use INDEX=/opt/dovecot/%2.256Nu/%u:ITERINDEX The restart dovecot and re-login the Imap client. All IMAP folders are rebuilt but the same folders like before are still missing. Any ideas please? thanks, Frank doveconf -n # 2.3.21.1 (d492236fa0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.21.1 (49005e73) # OS: Linux 5.15.149-1-pve x86_64 AlmaLinux release 8.10 (Cerulean Leopard) # Hostname: *** auth_verbose = yes disable_plaintext_auth = no doveadm_password = # hidden, use -P to show it first_valid_uid = 1000 imap_id_send = lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lmtp_save_to_detail_mailbox = yes log_path = /var/log/dovecot.log login_greeting = IMAP ready. mail_fsync = always mail_full_filesystem_access = yes mail_gid = 1000 mail_home = /srv/mail/mail_storage2/%d/%n mail_location = maildir:~/mail:VOLATILEDIR=/dev/shm/dovecot/%2.256Nu/%u:INDEX=/opt/dovecot/%2.256Nu/%u:ITERINDEX mail_plugins = " notify replication" mail_privileged_group = vpostfix mail_uid = 1000 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 vacation-seconds mbox_write_locks = fcntl mmap_disable = yes namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { special_use = \Trash } prefix = } passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { recipient_delimiter = + replication_full_sync_interval = 1 hour sieve = file:~/sieve;active=~/.dovecot.sieve sieve_before = /etc/dovecot/spam-global.sieve sieve_extensions = +vacation-seconds sieve_vacation_default_period = 1d sieve_vacation_max_period = 30d sieve_vacation_min_period = 0 sieve_vacation_use_original_recipient = yes } postmaster_address = ***** protocols = imap pop3 lmtp sieve service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = vpostfix } unix_listener replication-notify { mode = 0666 user = vpostfix } } service auth { inet_listener { address = 192.168.130.192 port = 3659 } unix_listener /var/spool/postfix/private/auth { group = vpostfix mode = 0666 user = vpostfix } unix_listener auth-userdb { group = vpostfix mode = 0600 user = vpostfix } } service config { unix_listener config { user = vpostfix } } service doveadm { inet_listener { port = 4711 } user = vpostfix } service imap-login { process_min_avail = 1 service_count = 1 } service lmtp { inet_listener lmtp { address = 192.168.130.192 port = 24 } } service managesieve-login { inet_listener sieve { port = 4190 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0666 user = vpostfix } } ssl_alt_cert = </etc/alt/fullchain.pem ssl_alt_key = # hidden, use -P to show it ssl_cert = </etc/fullchain.pem ssl_cipher_list = PROFILE=SYSTEM ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } protocol lmtp { mail_plugins = " notify replication sieve" } protocol lda { mail_plugins = " notify replication sieve" } protocol imap { mail_max_userip_connections = 10 mail_plugins = " notify replication quota imap_quota" }

Uppercase username emails are rejected
by lua8ds＠proton.me 20 Oct '24

20 Oct '24

When a sender writes my email address with my username uppercase, e.g. USERNAME(a)name.com, in the to: field of their MUA, my mail server rejects that email. /var/log/mail.log prints: <USERNAME(a)redacted.com>: host mail.redacted.com[private/dovecot-lmtp] said: 550 5.1.1 > <USERNAME(a)redacted.com> User doesn't exist: USERNAME(a)redacted.com (in reply to RCPT TO > command) In the manual, I found that: auth_username_format Default: %Lu Formatting applied to username before querying the auth database. You can use the standard variables here. Examples: %Lu Lowercases the username [...] My current setting was not the default; I had: auth_username_format = %n So I updated that setting to: auth_username_format = %Lu expecting that %Lu would lowercase the username - and that my problem would be fixed. It does not though. Updating this setting not only prompts my email server to still reject USERNAME(a)redacted.com, but now also rejects (lowercase username) username(a)redacted.com (which my server had no issue receiving beforehand). So I reverted auth_username_format to: auth_username_format = %n Emails sent to username(a)redacted.com land in my mailbox again - but emails sent to USERNAME(a)redacted.com still don't. What can I try to troubleshoot? Which config file shall I share with you?

Piegeonhole and PATH variable
by Julien Salort 18 Oct '24

18 Oct '24

Hello, I have a dovecot-sieve rule that has been working fine for years which calls sa-learn whenever a message is moved from or to the Junk folder. Recently, but I don't know when it started exactly, this no longer works. I get the following error message in mail.log: dovecot: imap: Error: Use of uninitialized value $ENV{"PATH"} in split at /usr/lib/x86_64-linux-gnu/perl-base/File/Spec/Unix.pm line 136. Error: program exec:/usr/lib/dovecot/sieve-pipe/sa-learn-spam.sh (2526990): Forcibly terminated with signal 15 Error: sieve: failed to pipe message to program `sa-learn-spam.sh': refer to server log for more information. [2024-10-16 10:16:51] Error: sieve: Execution of script /usr/lib/dovecot/sieve-pipe/report-spam.sieve failed The content of report-spam.sieve is require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"]; if environment :matches "imap.user" "*" { set "username" "${1}"; } pipe :copy "sa-learn-spam.sh" [ "${username}" ]; So my guess is that one of the require on the first line triggers this Unix.pm, and it fails because somehow the PATH variable is not set in this context. However, I am at a complete loss to determine how to change the environment variable in the context of dovecot-sieve. And also, I am not sure why this would be required. Does somebody know how to fix this problem, or alternatively point me to the relevant part in the documentation? Thanks, Julien
