Build with MySQL -> libmysqlclient not found

Hi folks, just step into another problem and don't know why? If i try to configure dovecot with the following: > ./configure --prefix=/test/core/dovecot --with-ssldir=/test/core/dovecot/tls --with-mysql i get > ... > checking for auth_userokay... no > checking for mysql_config... NO > checking for mysql_init in -lmysqlclient... noconfigure: error: Can't build with MySQL support: libmysqlclient not found After that i've tried to configure with following: > LDFLAGS="-L/test/core/mariadb/lib" ./configure --prefix=/test/core/dovecot --with-ssldir=/test/core/dovecot/tls --with-mysql but with same result. The Content of "/test/core/mariadb/lib" is: libmariadbclient.a libmariadb.so -> libmariadb.so.3 libmariadb.so.3 libmysqlclient.a -> libmariadbclient.a libmysqlclient_r.a -> libmariadbclient.a libmysqlclient_r.so -> libmariadb.so.3 libmysqlclient.so -> libmariadb.so.3 libmysqlservices.a pkgconfigplugin Also the Path "/test/core/mariadb/lib/pkgconfig" is in the PKG_CONFIG_PATH variable and the Library-Path "/test/core/mariadb/lib" is known by the dynamic linker (/etc/ld.so.conf.d/mylibs.conf). So what am i doing wrong? My Dovecot version: 2.3.18 My Mariadb version: 10.6.5 My OS: Ubuntu 20.04

email location - files or sql
by Robert Moskowitz 25 Feb '22

25 Feb '22

I have been running a Dovecot based mail server for over 10 years and it is time (really past) to upgrade. I really don't want to roll my own anymore. Too much time and too many skills needed. Time to retire. But still want it 'in-house'. What I am seeing is that many of the packages seem to roll the messages into some SQL database. My Dovecot setup uses the /home/vmail/doman/../{cur,new,etc} tree structure. Is there any pros vs cons on this that I can read? Is there some nice packed mailserver I can drop on a Centos-arm server that has Dovecot under the covers and I can easily rsync my current mail store to it? Mail-in-a-box looks interesting. But I have not figured out its internals and if I have to worry about anything compiled for arm that is not part of the distro. Thanks in advance for help.

Messages reappearing in mailboxes as duplicates
by Andrew Skipper 23 Feb '22

23 Feb '22

Hello, We have 3 nodes running, with a two way replication between 2 of them and a 1 way replication to a DR node running off one. We use mdbox, and directors to split traffic across nodes. There is no shared file system. Users are experiencing messages reappearing in their INBOX as unread with duplicate GUID and message headers. This occurs generally several days after a message was first received (and often actioned; read, moved, trashed, expunged, also often bulk moved/deleted). We have attempted to remove replication from the equation by cutting down to one single node with all replication disabled which did not have any impact. We have also started regular cache and mailbox purging. There are no logged events when mail items reappear, and we only observe it based on user report, mailbox inspection (doveadm looking for duplicate GUIDs/unique message headers) or seeing IMAP commands being done against the same message twice (e.g. monday they copy to trash, delete and expunge from inbox, delete and expunge from trash, then the next monday they will have to do the same for the reappearing message).

Pigeonhole page's RFC links broken (fix attached)
by Patrick Nagel 22 Feb '22

22 Feb '22

Hi there, I was just reading https://pigeonhole.dovecot.org/ and noticed that all the links to the RFCs are broken. I fixed them via regexp search & replace curl https://pigeonhole.dovecot.org/ | sed -e 's|https\?://tools.ietf.org/html/rfc\([0-9]\{4\}\)/\?|https://www.ietf.org/r…' >Pigeonhole_fixed_rfc_links.html and attached the resulting page. Cheers, Patrick.

postfix, dovecot-lda, /run/dovecot/stats-writer socket permision and local user delivery, again
by Michael Tokarev 22 Feb '22

22 Feb '22

Hi! There are many questions on the 'net about the same theme: lda(mjt): Error: net_connect_unix(/run/dovecot/stats-writer) failed: Permission denied dovecot-lda is run from postfix as mailbox_command for local users. There's even a suggestion on dovecot wiki to make dovecot-lda setgid (to mail) - for a different reason but people use this trick to shut this error message up. See eg the last message at https://forum.zentyal.org/index.php?topic=35236.0 which points to https://wiki2.dovecot.org/LDA/Postfix . But the thing is: mail delivery stops right after making dovecot-lda setgid, like this: Feb 22 00:06:46 tsrv dovecot: lda(mjt)<253650><s+nnHub+E2LS3gMA7tuOMA>: \ Fatal: setresgid(914(dovecot),914(dovecot),8(mail)) failed with euid=1000(mjt): \ Operation not permitted why the hell lda tries to setuid to dovecot user? It will definitely unable to write to the maildir since it is owned by user mjt, not by user dovecot! And I *only* made it setgid, not setuid. How to use dovecot-lda together with postfix, after all? Thanks, /mjt

No, the problem is the logging of the cache lookup with password mismatch.

/usr/libexec/dovecot/anvil crashes immediately
by Friedrich Kink 21 Feb '22

21 Feb '22

Dear list, I built a dovecot package for openindiana (which is a Solaris derivative) from latest version 2.3.18. Everything compiles and builds fine without any issue. Even subsequent installation and startup of main dovecot process works as expected. But execution of /usr/libexec/dovecot/anvil immediately crashes. To get some more meaningful backtrace I compiled with -g. Below some facts of my environment and a backtrace. Maybe some of you are more familiar with this kind of issue as I, and can give some hint or share ideas how to nail down the problem. Or can it be a configuration issue? BTW it is running in a so-called zone. And former versions, I don't know exactly but I believe up to 2.3.17, did not show this crash. gcc --version gcc (OpenIndiana 7.5.0-il-0) 7.5.0 Configure parameters: gcc_OPT = -g CONFIGURE_OPTIONS+=
