LMTP and Sieve with <prefix><recipient_delimiter><user>
by Paul Muster 11 Jun '19

11 Jun '19

Hi there, Dovecot's LMTP implementation and Pigeonhole Sieve already do support the <user><delimiter><suffix> format. RfC 5233, the Sieve subaddress extension, also offers <prefix><delimiter><user>. Could Docecot's LMTP and Pigeonhole be extended to that effect? Thanks & greetings, Paul

Potfix+Dovecot with dsync replication problem
by Zeljko Dokman 10 Jun '19

10 Jun '19

Hi all, I am in need of some help. Straggling to make something work, trying to configure postfix and dovecote imap server with dovecote replication. Can’t figure out what is wrong with my configuration. Replication is working only for vmail user account, I am getting this error on my secondary server for all other users… dovecot: doveadm: Fatal: setgid(4015(zdokman) from userdb lookup) failed with euid=5000(vmail), gid=5000(vmail), egid=5000(vmail): Operation not permitted (This binary should probably be called with process group set to 4015(zdokman) instead of 5000(vmail)) primary server reports this error: dovecot: doveadm(zdokman): Error: doveadm server disconnected before handshake: EOF dovecot: doveadm(zdokman): Error: sync: Disconnected from remote: EOF doveadm replicator status '*' username priority fast sync full sync success sync failed vmail none 01:58:13 02:05:25 01:58:13 - zdokman none 00:00:25 02:55:26 - y test none 00:01:00 21:48:13 - y doveadm sync * doveadm(root): Fatal: execvp(Maildir) failed: Permission denied dsync-local(root): Error: read(remote) failed: EOF (version not received) I am attaching my dovecot.conf main.cf and master.cf. I think my problem is with permissions but I can figure out how to workaround it. Best regards

Sql user and maildirs
by ＠lbutlr 10 Jun '19

10 Jun '19

For many years I had the following in my dovecot.conf: userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=/usr/local/virtual/%u/Maildir mail=maildir:/usr/local/virtual/%u/Maildir driver = sql } Recently, I started having quite a lot of errors on one MySQL account (used as a bcc backup account) along the lines of Fatal: Namespace '': Ambiguous mail location setting, don't know what to do with it: /usr/local/virtual/backup@domain/Maildir (try prefixing it with mbox: or maildir: Messages were sitting in the mail and were also getting dumped into /usr/local/virtual/backup@domain/new and I ended up running a fun little awk to move them into the right folders: grep -r "<backup+" . |awk -F: '{t=tolower($2); f=tolower($1); gsub(/@.*/, "/", t); sub(/<backup\+/, "../Maildir/", t); sub(/\.\//, "",f); cmd="mv " f" “t; system(cmd); }’ So I changed my doevecot.conf to: userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=maildir:/usr/local/virtual/%u/Maildir mail=maildir:/usr/local/virtual/%u/Maildir driver = sql } And the errors went away. So, no problem here to solve, but I am curious why I haven’t been having issues until quite recently? Was there a change or have I stumbled into something where it only looks like I’ve fixed the issue? In case it matters? # cat dovecot-sql.conf.ex [7:57] [/etc/dovecot] driver = mysql connect = host=localhost dbname=postfixusers user=dovecot password=x default_pass_scheme = SHA256-CRYPT password_query = select password FROM mailbox where username ='%u' user_query = select 89 as uid, 89 as gid, concat('/usr/local/virtual/', maildir, 'Maildir') as home FROM mailbox where username = '%u' The only ‘recent’ change I’ve made to my configuration was creating the Maildir/ subfolder for all the virtual users instead of using the ‘mailder’ from the sql table (that is, I added “, ‘Maildir’” to the concat, but that was quite awhile ago. I’m pretty sure I’d have noticed this before. Is that user_query as it should be or should I set concat('/usr/local/virtual/', maildir) as home and also set concat(‘maildir:/usr/local/virtual/', maildir, 'Maildir') as mail here rather than in the userdb block? -- K is for KATE who was struck by an axe L is for Leo who swallowed some tacks

Re: doveconf complains No matches on !include conf.d/* line but still writes out contents in conf.d
by Ben Ma 09 Jun '19

09 Jun '19

Further investigation shows that `doveconf` called `/usr/lib/dovecot/managesieve` which in return calls `doveconf` again, but with another uid (possible? I'm not sure) and a few extra arguments, which causes a call to `glob` in `src/config/config-parser.c:settings_include` to fail with `GLOB_NOMATCH`. I'd be appreciate if anyone can provide information on suspicious permission-relating operation that `managesieve` does before calling `doveconf`. I just can't find a way to post reply on previous mails, so I decided to post a new one. The original text follows. On 2019/6/6 3:15, Ben Ma wrote: > I'm on dovecot 2.3.3 (dcead646b).

since moving/upgrading system I've noticed I no longer get sieve script compiled, there is no dovecot.svbin created in /var/vmail/vmail1/sbt.net.au/voytek(a)tld.au/sieve what am I missing, how to check ? also, looking at sieve.log, I see a lot of May 31 06:32:50 lda(voytek(a)sbt.net.au)<1234><c4aVBfI98FzSBAAAyLbbsQ>: Error: sieve: Failed to initialize script execution: Invalid postmaster_address: invalid address `root' specified for the postmaster_address setting # grep root dovecot.conf postmaster_address = root what should I have ? # dovecot --version 2.3.6 (7eab80676)

FTS Xapian
by Daniel Miller 09 Jun '19

09 Jun '19

For my primary namespace this is working fine - thanks to the developers! It also appears to work great for shared folders as well. But my virtual folders aren't returning results - at least not to the client. The logs show FTS Xapian opening several DB files and getting results - but nothing is being returned to client. Is this a config issue on my side or is this a current limitation of the plugin? -- Daniel
