Private \seen flags lost during message move for other users
by Cube . 28 Mar '22

28 Mar '22

Hello, I have a shared mailbox set up with a private index: maildir:/var/mail/public:INDEXPVT=~/Maildir/public Per user \Seen flags are working fine until one user moves a message into another folder/sub-mailbox. For that user doing the move the message remains \Seen however for other users who have already seen the message the flag is lost and it appears unread in the new location. If the message is moved back it still appears unread to the other user even if had been read in that folder/sub-mailbox in the past. Is there anyway to retain per user \Seen that follows the message when its moved? Thank you.

imap_metadata plugin panic
by Elisamuel Resto 23 Mar '22

23 Mar '22

Hello, This may be covered somewhere but recently I enabled the metadata plugin to work with sieve as part of some updates I did a while back and I hadn't checked my logs for any issues with it and so far they're not completely taking my system down. Right now, upon trying to delete a folder I noticed the following in my logs... what am I missing? I see the broken SQL query, but I don't know enough about the dict system or the metadata plugin to know how to add the missing information or fix it otherwise. Regards, Elisamuel Resto Nov 15 12:19:19 wyvern dovecot[461]: dict(51438): Panic: lib-sql: Too many bind args (2) for statement: SELECT meta_key FROM metadata WHERE meta_key LIKE AND username = ?

Issue in 2.3.18 with fts_header_excludes/includes
by Alessio Cecchi 03 Mar '22

03 Mar '22

Hi, I'm still doing some test with fts-flatcurve, after updating to 2.3.18 I enabled: fts_header_excludes = * fts_header_includes = From To Cc Bcc Subject Message-ID but when I try to re-index all messages with FTS flatcurve the fts-flatcurve/ folder inside the Maildir/ become huge. Taking for example a Maildir with cur folder of 1.1G the related fts-flatcurve folder passed from 140M to 2.2G. After remove fts_header_excludes/includes config options, and re-index all messages, the fts-flatcurve/ size return to normal size. Is an issue? Thanks -- Alessio Cecchi Postmaster @http://www.qboxmail.it https://www.linkedin.com/in/alessice

General Locking & Replication Issues
by Paul Kudla (Scom.ca Internet Services Inc.) 01 Mar '22

01 Mar '22

Ok I am running two dovecot servers and feel pretty close to getting things resolved config wise there are however 2 or 3 issues that all seem to be related i have enclosed FULL config files for both mail18.scom.ca & mail19.scom.ca I have a private network that is used for the replication (10.221.0.0/24) - port 12345 is blocked by pf firewall from outside. I am running freebsd 12.1 and built one server and then raid copied it to the second (mail19) so all the ports / builds etc are identical I did start with dovecot-2.3.14 but pigeonhole would not build on freebsd (thanks for that advice / reply )until upgrade to dovecot-2.3.18 dovecot-2.3.18 was built and installed on both servers along with a good build (freebsd build error was fixed after upgrading) dovecot-2.3-pigeonhole-0.5.18 please note that the second mailserver (mail19) is on an nfs share dedicated to the server (i am awaiting sdram drives to replace this issue) but since i am getting errors on both servers i feel nfs share is not the issue (and yes i enabled dlock) mail18 is on normal sdram drives (more of an fyi as i dont think this is the issue) neither mail server is connected to the other in any kind of a shared way - other then replication postfix should be delivering via : pipe -n dovecot -t unix flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} Replication only works properly at startup (ie the mail boxes do sync), afterwhich nothing seems to trigger the differences between the servers to update (notify i believe) manually running : [05:04:46] mail18.scom.ca [root:0] /usr/local/etc/dovecot # doveadm sync -u paul(a)scom.ca remote:10.221.0.19 & [05:21:18] mail19.scom.ca [root:0] /usr/local/etc/dovecot # doveadm sync -u paul(a)scom.ca remote:10.221.0.18 does seem to work but with mixed results. I also included postfix main.cf & master.cf as well as some googling has indicated the file locking may be on the postfix side ?? Also more then happy to donate just can not figure out how ??? so that being said : General logging errors are as follows ?

By default, that is the UNIX # compatible delivery agent that lookups all recipients in /etc/passwd # and /etc/aliases or their equivalent. # # The default is $myhostname + localhost.$mydomain. On a mail domain # gateway, you should also include $mydomain. # # Do not specify the names of virtual domains - those domains are # specified elsewhere (see VIRTUAL_README). # # Do not specify the names of domains that this machine is backup MX # host for. Specify those names via the relay_domains settings for # the SMTP server, or use permit_mx_backup if you are lazy (see # STANDARD_CONFIGURATION_README). # # The local machine is always the final destination for mail addressed # to user(a)[the.net.work.address] of an interface that the mail system # receives mail on (see the inet_interfaces parameter). # # Specify a list of host or domain names, /file/name or type:table # patterns, separated by commas and/or whitespace. A /file/name # pattern is replaced by its contents; a type:table is matched when # a name matches a lookup key (the right-hand side is ignored). # Continue long lines by starting the next line with whitespace. # # See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS". # #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, # mail.$mydomain, www.$mydomain, ftp.$mydomain # REJECTING MAIL FOR UNKNOWN LOCAL USERS # # The local_recipient_maps parameter specifies optional lookup tables # with all names or addresses of users that are local with respect # to $mydestination, $inet_interfaces or $proxy_interfaces. # # If this parameter is defined, then the SMTP server will reject # mail for unknown local users. This parameter is defined by default. # # To turn off local recipient checking in the SMTP server, specify # local_recipient_maps = (i.e. empty). # # The default setting assumes that you use the default Postfix local # delivery agent for local delivery. You need to update the # local_recipient_maps setting if: # # - You define $mydestination domain recipients in files other than # /etc/passwd, /etc/aliases, or the $virtual_alias_maps files. # For example, you define $mydestination domain recipients in # the $virtual_mailbox_maps files. # # - You redefine the local delivery agent in master.cf. # # - You redefine the "local_transport" setting in main.cf. # # - You use the "luser_relay", "mailbox_transport", or "fallback_transport" # feature of the Postfix local delivery agent (see local(8)). # # Details are described in the LOCAL_RECIPIENT_README file. # # Beware: if the Postfix SMTP server runs chrooted, you probably have # to access the passwd file via the proxymap service, in order to # overcome chroot restrictions. The alternative, having a copy of # the system passwd file in the chroot jail is just not practical. # # The right-hand side of the lookup tables is conveniently ignored. # In the left-hand side, specify a bare username, an @domain.tld # wild-card, or specify a user(a)domain.tld address. # local_recipient_maps = unix:passwd.byname $alias_maps #local_recipient_maps = proxy:unix:passwd.byname $alias_maps #local_recipient_maps = # The unknown_local_recipient_reject_code specifies the SMTP server # response code when a recipient domain matches $mydestination or # ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty # and the recipient address or address local-part is not found. # # The default setting is 550 (reject mail) but it is safer to start # with 450 (try again later) until you are certain that your # local_recipient_maps settings are OK. # #unknown_local_recipient_reject_code = 450 #Set by Mailscanner # TRUST AND RELAY CONTROL # The mynetworks parameter specifies the list of "trusted" SMTP # clients that have more privileges than "strangers". # # In particular, "trusted" SMTP clients are allowed to relay mail # through Postfix. See the smtpd_recipient_restrictions parameter # in postconf(5). # # You can specify the list of "trusted" network addresses by hand # or you can let Postfix do it for you (which is the default). # # By default (mynetworks_style = subnet), Postfix "trusts" SMTP # clients in the same IP subnetworks as the local machine. # On Linux, this does works correctly only with interfaces specified # with the "ifconfig" command. # # Specify "mynetworks_style = class" when Postfix should "trust" SMTP # clients in the same IP class A/B/C networks as the local machine. # Don't do this with a dialup site - it would cause Postfix to "trust" # your entire provider's network.

Continue # long lines by starting the next line with whitespace. A file name # is replaced by its contents; a type:name table is matched when a # (parent) domain appears as lookup key. # # NOTE: Postfix will not automatically forward mail for domains that # list this system as their primary or backup MX host. See the # permit_mx_backup restriction description in postconf(5). # relay_domains = $mydestination # INTERNET OR INTRANET # The relayhost parameter specifies the default host to send mail to # when no entry is matched in the optional transport(5) table. When # no relayhost is given, mail is routed directly to the destination. # # On an intranet, specify the organizational domain name. If your # internal DNS uses no MX records, specify the name of the intranet # gateway host instead. # # In the case of SMTP, specify a domain, host, host:port, [host]:port, # [address] or [address]:port; the form [host] turns off MX lookups. # # If you're connected via UUCP, see also the default_transport parameter. # #relayhost = [gateway.my.domain] #relayhost = [mailserver.isp.tld] #relayhost = uucphost #relayhost = [an.ip.add.ress] # REJECTING UNKNOWN RELAY USERS # # The relay_recipient_maps parameter specifies optional lookup tables # with all addresses in the domains that match $relay_domains. # # If this parameter is defined, then the SMTP server will reject # mail for unknown relay users.

This feature is turned on by default, although it # still needs further development (it's disabled on SCO UNIX due # to an SCO bug). # # A Postfix process will pause for $in_flow_delay seconds before # accepting a new message, when the message arrival rate exceeds the # message delivery rate. With the default 100 SMTP server process # limit, this limits the mail inflow to 100 messages a second more # than the number of messages delivered per second. # # Specify 0 to disable the feature.

Build with MySQL -> libmysqlclient not found
by Dimitri 28 Feb '22

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

Hi John, i just want to manage all the software manually, use own directorie-structur and have all the programs in one place, deepen my understanding how these programs work and build these programs only with the components i need.

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.
