JWT local validation
by Tomas Habarta 11 Aug '21

11 Aug '21

Hello, I have a working setup with Roundcube using OAuth2 -- introspection works without any problem, unfortunately local validation does not as tokens are missing "typ" header (seems that one is indeed optional per RFC7519 and therefore not present in the implementation in place). Is there any parameter to assert the token type or any other workaround to make local validation work as it currently fails with: oauth2 failed: Local validation failed: Cannot find 'typ' field. dovecot v2.3.15 Roundcube 1.5beta CentOS 8 Thanks, regards Tomas

Pigeonhole Sieve Config Warning
by dovecot＠ptld.com 09 Aug '21

09 Aug '21

In the sieve plugin settings i have plugin { ... sieve_user_email = %u } Variables pages says %u = full username (e.g. user@domain) This config seems to work in practice, the email is from: the users email address. However on starting dovecot im getting a warning twice: dovecot[35893]: managesieve: Warning: sieve: Invalid address value for setting `sieve_user_email': Missing domain dovecot[35893]: master: Dovecot v2.3.8 (9df20d2db) starting up for imap, lmtp, sieve dovecot[35897]: managesieve: Warning: sieve: Invalid address value for setting `sieve_user_email': Missing domain So is there really an issue? Or just an improper warning?

dsync and sieve script
by Andrea Gabellini 09 Aug '21

09 Aug '21

Hello, I'm testing the migration from and old dovecot server 2.2.24 to a new one with 2.3.15 using this command: doveadm -c /etc/dovecot/dovecot-migration.conf -o mail_fsync=never backup -x "shared" -x "shared/*" -x "dovecot/sieve" -R -T 60 -u andrea.gabellini.sc(a)telecomitalia.sm imapc: This command replicate email messages but not the sieve scripts. The esclusion of "dovecot/sieve" is mandatory because the old server is misconfigured and doesn't have a separate home and maildir location. Is dsync able to replicate the sieve scripts or I'm doing something wrong?

quota_grace

There isn't much documentation on quota_grace. How would you disable quota grace? quota_grace = 0 quota_grace = 0% quota_grace = 0m quota_grace = -1 Assuming "0" isn't an "unlimited" setting?

Timo - is the v2.3.15 GCC limitation really necessarily or it's just a bug?
by Mart Pirita 02 Aug '21

02 Aug '21

Hello. So far I have successfully built Dovecot until v2.3.14 on Centos 4-6 (yes I know, they are old, but as they are remote servers, distros can't upgraded), and sometimes I have also met compilation issues, but after highlighting them, Timo have fixed the code. Found from similar thread (Dovecot 2.3.15 compilation fails https://dovecot.org/list/dovecot/2021-June/122412.html ) that new GCC is needed. However I can't find such requirement in v2.3.15 change log. As seems that I'm not the only one with compilation issues, then @Timo - can You please fix the code so that also v2.3.15 can compiled on older distros? Compilation options: ./configure --prefix=/usr --with-ssl=openssl --with-ssldir=/etc/ssl --sysconfdir=/etc --with-pam --without-bsdauth --without-sql --without-nss --without-ldap --without-pgsql --without-mysql --without-sqlite --with-rundir=/var/run/dovecot --without-cassandra --without-lucene --without-solr --without-textcat --without-libcap --without-stemmer --disable-rpath --disable-dependency-tracking --disable-silent-rules --without-gssapi --without-cdb Compilation error: builtin-strftime -c -o test-smtp-params.o test-smtp-params.c test-smtp-params.c:29: error: unknown field `data' specified in initializer test-smtp-params.c:29: warning: missing braces around initializer test-smtp-params.c:29: warning: (near initialization for `test_params_buffer1.<anonymous>') test-smtp-params.c:30: warning: missing initializer test-smtp-params.c:30: warning: (near initialization for `test_params_buffer1.<anonymous>.<anonymous>.used') test-smtp-params.c:30: error: unknown field `used' specified in initializer test-smtp-params.c:31: warning: excess elements in struct initializer test-smtp-params.c:31: warning: (near initialization for `test_params_buffer1') test-smtp-params.c:33: error: unknown field `data' specified in initializer test-smtp-params.c:33: warning: missing braces around initializer test-smtp-params.c:33: warning: (near initialization for `test_params_buffer2.<anonymous>') test-smtp-params.c:34: warning: missing initializer test-smtp-params.c:34: warning: (near initialization for `test_params_buffer2.<anonymous>.<anonymous>.used') test-smtp-params.c:34: error: unknown field `used' specified in initializer test-smtp-params.c:35: warning: excess elements in struct initializer test-smtp-params.c:35: warning: (near initialization for `test_params_buffer2') make[3]: *** [test-smtp-params.o] Error 1 make[3]: Leaving directory `/usr/src/redhat/BUILD/dovecot-2.3.15/src/lib-smtp' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/src/redhat/BUILD/dovecot-2.3.15/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/redhat/BUILD/dovecot-2.3.15' make: *** [all] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.7364 (%build) -- Mart

SQL Backend for IMAP METADATA Dictionary
by Joseph D Wagner 01 Aug '21

01 Aug '21

I've seen documentation on using a SQL backend for quota dictionary and passdb&userdb dictionary. However, I can't find any examples of a SQL backend for IMAP METADATA / mail_attributes_dict. Is this combination possible? If so, is there an example somewhere? I am unsure what data structures it's expected or how to create the map entries for it. Thanks in advance. Joseph D. Wagner

Re: check_policy_service sends size=0

> It sounds like a better approach would be to make Dovecot reject any > email no matter what the size is (even size=0) if a user is over > quota. I'll take further discussion to the dovecot mailing list then. If you are not aware, dovecot has by default a 10% over quota grace. So even being a couple of bytes over quota it would still accept a small message.
