Bug: dovecot 2.3.21.1 fails to build with recent ICU
by Marcel Telka 01 Apr '25

Hi, dovecot 2.3.21.1 fails to build with ICU 77. There are also reports it does not build with ICU 76 for the same reason: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=284832 There is no issue when built with ICU 75. The failure is this: /bin/bash ../../libtool --tag=CC --mode=link /usr/gcc/14/bin/gcc -std=gnu99 -m64 -O3 -Wno-incompatible-pointer-types -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=keep -mindirect-branch=keep -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/openssl/3/include -no-undefined -m64 -o test-fts-icu test-fts-icu.o fts-icu.lo -licui18n ../lib-test/libtest.la ../lib/liblib.la -lsocket -lnsl -lsendfile libtool: link: /usr/gcc/14/bin/gcc -std=gnu99 -m64 -O3 -Wno-incompatible-pointer-types -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=keep -mindirect-branch=keep -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/openssl/3/include -m64 -o test-fts-icu test-fts-icu.o .libs/fts-icu.o -licui18n ../lib-test/.libs/libtest.a ../lib/.libs/liblib.a -lsocket -lnsl -lsendfile Undefined first referenced symbol in file ucasemap_utf8ToLower_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) u_strFromUTF8Lenient_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) u_errorName_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) u_cleanup_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) ucasemap_close_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) u_strToUTF8WithSub_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) ucasemap_open_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) ld: fatal: symbol referencing errors. No output written to test-fts-icu collect2: error: ld returned 1 exit status The workaround is easy: to add -licuuc to LDFLAGS, however it would be great if dovecot builds without any workarounds needed.

Dovecot v2.4.1 released
by Aki Tuomi 31 Mar '25

31 Mar '25

Hi! We arey happy to release Dovecot v2.4.1! Some IMPORTANT things to notice (still): - We have changed the signing key for 2.4 going forward, releases are signed with EF0882079FD4ED32BF8B23B2A1B09EF84EDC5219, which can be found at https://repo.dovecot.org/DOVECOT-REPO-GPG-2.4 and is signed with the previous key. The old key has been renamed to https://repo.dovecot.org/DOVECOT-REPO-GPG-2.3. - New 2.4 packages **are not** compatible with old 2.3 configuration, please carefully review https://doc.dovecot.org/2.4.1/installation/upgrade/2.3-to-2.4.html before installing the new packages. - We are happy to provide experimental arm64 support in the form of a Docker image. There are now three kinds of images, latest, latest-dev and latest-root. - The latest docker image is now ran rootless, with UID 1000 as vmail. Please take this into consideration when upgrading. The latest-root image still runs as root. Latest 2.3 image can be used with tag 2.3-latest still We won't be sending separate mail about Pigeonhole anymore as we will release one anyways when we release Dovecot, and Pigeonhole versioning has been changed to match Dovecot versioning.

Bug: Inconsistency in configuration between various clients.
by Louis Schmitz 27 Mar '25

27 Mar '25

We found out about this through a misconfiguration in our web panel. In the main config file the following line includes a subdirectory; !include conf.d/*.conf The web panel created the following two relevant configuration snippets in /etc/dovecot/conf.d/ 11-plesk-security-ssl.conf > ssl_dh=</opt/psa/etc/dhparams2048.pem > ssl_min_protocol=TLSv1.2 > ssl_cipher_list=EECDH+AESGCM+AES128:EECDH+AESGCM+AES256:EECDH+CHACHA20:EECDH+SHA256+AES128:EECDH+SHA384+AES256:EECDH+SHA1+AES128:EECDH+SHA1+AES256:EECDH+HIGH:AESGCM+AES128:AESGCM+AES256:CHACHA20:SHA256+AES128:SHA256+AES256:SHA1+AES128:SHA1+AES256:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!3DES:!MD5:!PSK:!KRB5:!aECDH:!kDH:!EDH > ssl_prefer_server_ciphers=yes > ssl=yes > ssl_cert=</etc/dovecot/private/dovecot.pem > ssl_key=</etc/dovecot/private/dovecot.pem This sets a server wide certificate as being the cert in /etc/dovecot/private/dovecot.pem. Let's say our main server domain is 'acme.com' for example, its 'hostname' (linux hostname) is for example 's02.acme.com'. Then it would also create 14-plesk-sni-mail.acme.com.conf, containing something akin to: > local_name mail.acme.com { > ssl_cert = </opt/psa/var/certificates/scf7b9lcY > ssl_key = </opt/psa/var/certificates/scf7b9lcY > } These point to the ssl cert and key configured for that specific vhost (not the entire server), which can be different from that configured for the server. When some clients connected to the server (connecting to mail.acme.com) it would serve the /etc/dovecot/private/dovecot.pem certificate. This was renewed and the clients would work without issue. Other clients, however, used the certificate at /opt/psa/var/certificates/scf7b9lcY. This certificate is supposed to be the same, but expired and wasn't renewed along with the other one. This was tricky to figure out since the problems did not appear on our side, only when looking at a client. Once I went around the panel GUI and into the actual dovecot configuration files I found the culprit(s). I think, but do not know, that it could be related to which IP protocol (V4 or V6) is used to connect to dovecot. All clients who failed happened to connect over V6. The cases that did not used V4. This seems entirely unrelated and strange behaviour that must be a bug of some kind. Either both should use the one certificate, or the other, or there should be an error or warning if local_name includes a variant subdomain of the server name, the latter in addition to making a consistent choice. It appears that sometimes the first relevant ssl_key and ssl_cert are used, and other times the second when the option is included twice in the configuration, pointing to different matching certificates/keys. It's not apparently a race condition: The behaviour is very consistent for the same client connecting.

Input Buffer Full with OAuth login
by Brad Koehn 26 Mar '25

26 Mar '25

I’m running Dovecot 2.3.21.1 using Authentik for OAuth authentication. I’m using SOGo 5.12.0 as a UI, also with OAuth authentication. When SOGo connects to Dovecot and authenticates with OAuth, it fails and the following is logged: imap-login: Info: Disconnected: Input buffer full (no auth attempts in 0 secs): user=<>, rip=10.42.1.1, lip=10.42.1.196, TLS, session=<NZnp7zMxQuMKKgEB> My dovecot-oauth2.conf.ext looks like this: openid_configuration_url = https://auth.koehn.com/application/o/dovecot-oauth2/.well-known/openid-conf… introspection_url = https://auth.koehn.com/application/o/introspect/ introspection_mode = post client_id = [redacted] client_secret = [redacted] username_attribute = email debug = yes rawlog_dir = /tmp/oauth2 And my auth-oauth2.conf.ext looks like this: passdb { driver = oauth2 mechanisms = xoauth2 oauthbearer args = /etc/dovecot/conf.d/dovecot-oauth2.conf.ext } I’m using the Dovecot Debian packages from repo.dovecot.org. I’ve tried auth for introspection_mode, to no avail. There’s nothing extra in the logs when I turn on debug, and there’s nothing logged in the /tmp/oauth2 directory either, FWIW.

Dovecot and IP check at the user connection (auth-worker problems: no IP...)
by ik7xja＠gmail.com 26 Mar '25

26 Mar '25

Hi to all, I'm using Postfix and Dovecot for my little server. I'm experimenting many false user caming fron the entire world to access to my account. I'm only in a country and I would like to restrict accesso to user coming from IPs located in my country. Since the access is granteg by mysql and SQL in passdb and userdb, I've created a table with only the IPs of my country and check the user remote IP. The trick is working well when I try to access to my account beacuse the variable "%r" is not empy... But... But when there is a delivery of a new message, the auth-worker have no IP and the check fail: auth-worker<5>: sql(user(a)my.domain): unknown user and the new message, coming in my box from other servers come back to the sender as "unknown user" There is a way to user a different query in this auth-worker process (I guess is using the same SQL with the IP-check)? Or "force" an IP (like 127.0.0.1) in the auth-worker invocation? Thanks in advance for any advice.

Appending n solr deployment configuration following two lines:- SOLR_OPTS="$SOLR_OPTS -Dsolr.config.lib.enabled=true" SOLR_MODULES=extraction,ltr,analysis-extras Also, additional note there are some other minor log warning, but weren't problematic.

Dovecot 2.4: Segfault for "doveadm proxy kick foo bar"
by Michael Goth 25 Mar '25

25 Mar '25

Hi! The following command segfaults on Dovecot 2.4: #> doveadm proxy kick foo bar Segmentation fault (core dumped) Giving only one user (doveadm proxy kick foo) works: #> doveadm proxy kick foo 0 connections kicked It does not matter if the users actually exist on the server (so the above command can be used verbatim). This used to work in Dovecot 2.3. I'm running Dovecot 2.4 on Ubuntu 24.04, installed from repo.dovecot.org. Regards, Michael

lost emails - Opened mail because: snippet ?
by Arkadiusz Miśkiewicz 24 Mar '25

24 Mar '25

Hello. I'm tracking a weird case where dovecot (it's 2.3.21.1) looses incoming emails. Email is delivered over LMTP with full success (in theory). From lmtp raw log: 1742822341.735762 250 2.0.0 <examplelogin@mbox> +LpAG8Vb4Wc9OAAA9fPEKQ Saved 1742822341.735918 221 2.0.0 Bye Log says it got saved: Mar 24 14:19:01 mbox dovecot[22785]: lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, msgid=<XYZ...1611.EURP189.PROD.OUTLOOK.COM>, storage_id=1742822341.M462393P14397.mbox,S=139039,W=141006, delivery_status=saved mail to INBOX There is a file name but # find /var/mail/examplelogin/ -name '1742822341.M462393P14397.mbox*' # nothing. Well, someone could delete or move this email, right? But no, that's not the case, only pop3 sessions around: > Mar 24 14:18:43 mbox dovecot[22785]: pop3(examplelogin): pid=<24041> session=<rX98cRYxIvlTDCet>, Disconnected: Logged out top=0/0, retr=0/0, del=0/20, size=5204114, in=24, out=1002 > Mar 24 14:19:01 mbox dovecot[22785]: lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, msgid=<XYZ...1611.EURP189.PROD.OUTLOOK.COM>, storage_id=1742822341.M462393P14397.mbox,S=139039,W=141006, delivery_status=saved mail to INBOX > Mar 24 14:19:43 mbox dovecot[22785]: pop3-login: Login: user=<examplelogin>, method=PLAIN, rip=1.1.1.1, rport=63799, lip=2.2.2.2, lport=110, mpid=27238, session=<GPgZdRYxN/lTDCet> > Mar 24 14:19:44 mbox dovecot[22785]: pop3(examplelogin): pid=<27238> session=<GPgZdRYxN/lTDCet>, Disconnected: Logged out top=0/0, retr=0/0, del=0/20, size=5204114, in=24, out=1002 Note the same number of total mails in del log before and after problematic mail delivery - "del=0/20", so dovecot doesn't see that new mail (there are few pop3 logins after that - all with del=0/20) So the conclusion is that the file, with email, was not created on the filesystem. LMTP raw session log, debug session log, nothing weird - below. BUT there is one thing: Debug: Mailbox INBOX: saving UID 0: Opened mail because: snippet (Mail not cached, highest cached seq=20 uid=31: reset_id=1742577355) "Opened mail because: snippet " - what does this mean? Out of 50k mails delivered only 160 have that "Opened mail because: snippet" and by that I mean that logged for lmtp like: Mar 24 07:25:18 lmtp(xyz): pid=<28535> session=<SPx6Ds764Gd3bwAA9fPEKQ>, Debug: Mailbox INBOX: saving UID 0: Opened mail because: snippet (Mail not cached, highest cached seq=291 uid=4094: reset_id=1579231568) The rest have "UID 0: Opened mail because: mail stream". Started looking at these snipped entries. It seems that almost every mail with this logged is missing on the filesystem(!). Huh, what could be happening here? debug log (is there a way to enable even more detailed/low level log?): > Mar 24 14:19:01 lmtp(examplelogin@mbox): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: auth-master: userdb lookup(examplelogin@mbox): Started userdb lookup > Mar 24 14:19:01 lmtp(examplelogin@mbox): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: auth-master: userdb lookup(examplelogin@mbox): auth USER input: examplelogin home=/var/mail/examplelogin/ mail=maildir:/var/mail/examplelogin/:CONTROL=/var/lib/dovecot/control/examplelogin:VOLATILEDIR=/var/lib/dovecot/control/examplelogin:INDEX=/var/lib/dovecot/control/examplelogin uid=1234 gid=7890 sieve_enabled=no > Mar 24 14:19:01 lmtp(examplelogin@mbox): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: auth-master: userdb lookup(examplelogin@mbox): Finished userdb lookup (username=examplelogin home=/var/mail/examplelogin/ mail=maildir:/var/mail/examplelogin/:CONTROL=/var/lib/dovecot/control/examplelogin:VOLATILEDIR=/var/lib/dovecot/control/examplelogin:INDEX=/var/lib/dovecot/control/examplelogin uid=1234 gid=7890 sieve_enabled=no) > Mar 24 14:19:01 lmtp(examplelogin@mbox): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: changed username to examplelogin > Mar 24 14:19:01 lmtp(examplelogin@mbox): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: lmtp-server: conn unix:pid=25252,uid=8 [89]: rcpt examplelogin@mbox: Added userdb setting: mail=maildir:/var/mail/examplelogin/:CONTROL=/var/lib/dovecot/control/examplelogin:VOLATILEDIR=/var/lib/dovecot/control/examplelogin:INDEX=/var/lib/dovecot/control/examplelogin > Mar 24 14:19:01 lmtp(examplelogin@mbox): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: lmtp-server: conn unix:pid=25252,uid=8 [89]: rcpt examplelogin@mbox: Added userdb setting: plugin/sieve_enabled=no > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: Effective uid=1234, gid=7890, home=/var/mail/examplelogin/ > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: Quota root: name=Calkowita przestrzen dla serwera backend=fs args=group > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: Quota grace: root=Calkowita przestrzen dla serwera bytes=0 (10%) > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: Quota root: name=Twoja przestrzen e-mail backend=fs args=user > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: Quota grace: root=Twoja przestrzen e-mail bytes=0 (10%) > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: Namespace inbox: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/var/mail/examplelogin/:CONTROL=/var/lib/dovecot/control/examplelogin:VOLATILEDIR=/var/lib/dovecot/control/examplelogin:INDEX=/var/lib/dovecot/control/examplelogin > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: maildir++: root=/var/mail/examplelogin, index=/var/lib/dovecot/control/examplelogin, indexpvt=, control=/var/lib/dovecot/control/examplelogin, inbox=/var/mail/examplelogin, alt= > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: quota-fs: fs quota add mailbox dir = /var/mail/examplelogin > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: quota-fs: fs quota block device = /dev/mapper/vg_sys-lv_home > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: quota-fs: fs quota mount point = /home > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: quota-fs: fs quota mount type = xfs > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: Namespace : type=private, prefix=, sep=, inbox=no, hidden=yes, list=no, subscriptions=no location=fail::LAYOUT=none > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: fts: Indexes disabled for namespace '' > Mar 24 14:19:01 lmtp(examplelogin): pid=<14397> session=<+LpAG8Vb4Wc9OAAA9fPEKQ>, Debug: quota: quota_over_flag check: quota_over_script unset -

Cannot retrieve private key from LDAP
by luis.neapolis＠gmail.com 22 Mar '25

22 Mar '25

Hello, I have a problem setting the mail-crypt plugin using global keys. First of all I prepare keys: penssl ecparam -genkey -name secp521r1 | openssl pkey -aes-256-cbc -passout pass:foobar | base64 -w0 >ecprivkey.pem cat ecprivkey_b64.pem | openssl ec -pubout > ecpubkey.pem Now I would like to pass these values using the LDAP passdb. My conf is: userdb ldap { driver = ldap ldap_filter = ... ldap filter ... fields { ... other fields ... crypt_global_public_key_file = inline:%{ldap:pubkey_in_pem_base64} crypt_global_private_key/main/crypt_private_key_file=inline:%{ldap:key_in_pem_base64} crypt_global_private_key/main/private_key_password=foobar } } mail_plugins { mail_crypt = yes } crypt_global_private_key main { # create the filter, but leave its settings empty } when I receive an email I have: lmtp(127004): Fatal: Raw user initialization failed: mail_crypt_plugin: main: Couldn't parse private key : Unknown key format I want to let you know that if I give same keys, without base64 encoding, to configuration: crypt_global_private_key main { crypt_private_key_file= /path/to/key } and: userdb ldap { ..... fields { ... other fields ... # crypt_global_private_key/main/crypt_private_key_file=inline:%{ldap:key_in_pem_base64} ... other fields ... } } all works. If I try to retrieve values from LDAP all is ok with: doveadm user user@domain Any suggestion? Thank you.
