Dovecot FST not using plugins
by Joan Moreau 12 Jan '21

12 Jan '21

Hello, With recent git version of dovecot, I can see that the FTS does not use the configured plugin anymore, but tries to sort the mailbox directly on the spot (which is of course very painful). Is there a change in the configuration file in order to recover the old behavior ? or something else has changed ? Thank you Joan

Remap login before authentication
by Miloslav Hůla 11 Jan '21

11 Jan '21

Hi, with Dovecot 2.3.4 I would like to allow user to login with two different usernames: - USERNAME (no domain) - now works - name.surname(a)domain.tld - would like to add Problem is, that the only authentication method I have is LDAP bind by USERNAME. Now I use: ============ passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } # Args uris = ldaps://ldap.domain.tld auth_bind = yes auth_bind_userdn = uid=%u,dc=domain,dc=tld base = ============ I know passdb can remap user&domain, but I have no password hash at all. And for example '{SASL}' is not supported password scheme to return e.g. from SQL passdb. Is there any way how to achive this? Maybe somehow remap username in first passdb and then continue to LDAP bind? 1. login as name.surname(a)domain.tld 2. remap to USERNAME 3. do the LDAP bind Milo

Re: status of test code

Update:I was finally able to build 2.3.13 on centos 8 (8.3). I managed this by going back to the qmailtoaster spec file, removing a few things no longer relevant (vpopmail) and disabling all the tests. Most tests were still running but there were also many that did not. The good news is the resulting executable in the RPM no longer complains about not being able to find libdovecot.so. i've done some basic testing on imap and everything appears to be working.Someone who maintains the tests and rpm build should really have a look. Doing a build on a fresh centos 8 machine, as I was able to with the qmailtoaster source rpm, should really be much simpler. My impression is the current spec file may have edits that were eroneously committed? SteveSent from my T-Mobile 4G LTE device------ Original message------From: steve(a)keptprivate.comDate: Sat, Jan 9, 2021 3:42 PMTo: dovecot(a)dovecot.org;Cc: Subject:status of test codeHi, I'm continuing to try to build 2.3.13 with a source RPM. At this point I've taken the source zip file and I'm working with the previously working qmailtoaster SPEC file and RPM build process. The toaster SPEC file runs the built-in dovecot tests after build... 2.3.11 would make it through all the tests with a few minor exceptions. 2.3.13 seems no longer able to run the test is lib-ssl-iostream or lib-lua (and perhaps others, but that's as far as I've gotten). I can selectively disable the tests to make progress, but it raises the question of what the plans are for the built-in tests. Also, I continue to not be able to find where all the testing is turned on/off at once? I'm sure it will be obvious when someone tells me but please tell me, because I'm pulling my hair out. Steve

lzma mdboxes with unexpected EOF
by Bjoern Franke 10 Jan '21

10 Jan '21

Hi, I'm running dovecot 2.3.13 (until 05.01. it was 2.3.11.3) on Arch Linux and used lzma compressed mdboxes. Yesterday a user called me that she is missing all mails from the beginning of the month until now. I took a look into the logs and saw several "lzma.read [...] unexpected EOF at <....>". As I had no clue why the mdboxes are broken, I tried to convert all 3 mailboxes to Maildir using "doveadm sync" to prevent further issues and stumbled upon several lzma errors for mdbox files of my own user. So I wrote a script which took the offset and size via "doveadm dump" und then dds the xz parts out of the broken mdboxes and extracts them via 7z. But I'm wondering why that happened at all. I stumpled upon [1] but there was no further discussion about it. Best Regards Bjoern [1]https://dovecot.org/pipermail/dovecot/2019-September/117007.html

auth error log format change
by Adrian Minta 10 Jan '21

10 Jan '21

Hi, we recently upgraded to 2.3.13 from 2.3.11 and the log format for auth errors seems to have change. This change may have an adverse effect on fail2ban rules. Is there a way to revert to old format ? Thank you ! Old log example: Jan 10 00:32:37 mail dovecot: auth-worker(50806): sql(name(a)domain,112.18.92.0.104,<Dg/+P3+49cMFt1xo>): Password mismatch Jan 10 03:20:02 mail dovecot: auth-worker(26057): sql(name(a)domain,112.18.92.0.104,<oMyxloG4M7AFt1xo>): Password mismatch New log example: Jan 10 00:32:37 mail dovecot: auth-worker(50806): conn unix:auth-worker (pid=22503,uid=0): auth-worker<585236>: sql(name(a)domain,112.18.92.0.104,<Dg/+P3+49cMFt1xo>): Password mismatch Jan 10 03:20:02 mail dovecot: auth-worker(26057): conn unix:auth-worker (pid=25928,uid=0): auth-worker<4234337>: sql(name(a)domain,112.18.92.0.104,<oMyxloG4M7AFt1xo>): Password mismatch -- Best regards, Adrian Minta

problem building on centos 8 (8.3 kernel)
by steve＠keptprivate.com 09 Jan '21

Hi, I'm converting from qmailtoaster/vpopmail build. When I try to build dovecot-2.3.13-2.src.rpm for centos 8.3 the first thing I run into is this: + sed -i 's|/etc/ssl|/etc/pki/dovecot|' doc/mkcert.sh doc/example-config/conf.d/10-ssl.conf + '[' -e buildinfo.commit ']' ++ head -1 buildinfo.commit + COMMIT=89f716dc2ec7362864a368d32533184b55fb7831 ++ /bin/sh /home/build/rpmbuild/SOURCES/lsb_release -is /bin/sh: /home/build/rpmbuild/SOURCES/lsb_release: No such file or directory + ID= error: Bad exit status from /var/tmp/rpm-tmp.WFaLYQ (%build) RPM build errors: Macro expanded in comment on line 455: %{_libdir}/dovecot/settings Bad exit status from /var/tmp/rpm-tmp.WFaLYQ (%build) I can get past this with an edit to the dovecot.spec file (removing sourcedir): if [ -e "buildinfo.commit" ]; then COMMIT=`head -1 buildinfo.commit` ID=`/bin/sh %̶{̶_̶s̶o̶u̶r̶c̶e̶d̶i̶r̶}̶/̶lsb_release -is` RELEASE=`/bin/sh %̶{̶_̶s̶o̶u̶r̶c̶e̶d̶i̶r̶}̶/̶lsb_release -rs` CODENAME=`/bin/sh %̶{̶_̶s̶o̶u̶r̶c̶e̶d̶i̶r̶}̶/̶lsb_release -cs` ARCH=`arch` fi The RPM builds but it fails to run with this message in the logs: Jan 6 20:52:11 beta1 systemd[1]: Starting Dovecot IMAP/POP3 email server...

Any ideas what I have going wrong? Also, a side question, when I build the rpm it's not running the extensive tests that the old qmailtoaster source rpm used to run. I've looked through the spec file and I don't really see where to turn that back on. Sorry if any of this is stupid, but I'm new to building directly from the dovecot repo. Steve

Another thought... Could I use a different build mechanism that would result in the same installation rpm?
