Fatal: -N parameter requires syncing with remote host

hi I get with default (not declared) replication_dsync_parameters above errors, and for users that I'm trying to disable replication. I'm trying to disable with: override_fields = mail_replica="" in userdb and just in case (ldap) also user_attrs = =mail_replica="" my replication conf is pretty basic: service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0660 } } service aggregator { fifo_listener replication-notify-fifo { user = vmail group = Domain Users mode = 0660 } unix_listener replication-notify { user = vmail group = Domain Users } } service doveadm { inet_listener { port = 12345 } } doveadm_password = secret # I can tell simple test: doveadm -v sync -f -u my(a)my.domain ssh vmail@server doveadm dsync-server -u me(a)my.domain works. It's for a user that I don't want replication. What am I missing here? many thanks

Re: Virtual Mailboxes

My next bonehead maneuver - was more of the first! location = virtual:/var/mail/%%d/%%n/mdbox/mailboxes/virtual was adapted from my definition for my shared namespace. Which was intended to share OTHER users - which is why the '%%' prefixes are used. Changing to: location = virtual:/var/mail/%d/%n/mdbox/mailboxes/virtual Now I can actually view something! But I still have a challenge - the mailboxes don't allow subscriptions via IMAP. If I manually edit the "subscriptions" file I can force it and I can now browse & view - but I can't make changes via IMAP clients. What else am I missing? -- Daniel On 2015-06-22 10:31, dmiller(a)amfes.com wrote: > Any ideas on what I need to check or should post to help find the > problem? > > -- > Daniel > > > On 2015-06-20 14:50, dmiller(a)amfes.com wrote: >> The first bonehead maneuver seems to be: >> location = virtual:/var/mail/%%d/%%n/mdbox/virtual >> I'm thinking it should be: >> location = virtual:/var/mail/%%d/%%n/mdbox/mailboxes/virtual >> >> But...it didn't seem to make a difference.

EXT4/LVM recommendations for 3TB of mdbox ?
by Nicolas C. 25 Jun '15

25 Jun '15

Hello, Do you have recommendations on EXT4 and LVM options for a 3TB file-system for mdbox? We currently use the mbox format on a XFS with poor performances since the update in v2.1 (Debian). We will switch to EXT4 to have the possibility of shrinking the file-system if needed (which is not possible with XFS), we currently have LVM partitions but with mdbox we will use LVM snapshots to backup the server in a consistent state. So, - any particular options to use with mkfs.ext4 for the creation of the FS ? - do you recommend a «thin» logical volume ? Our storage (IBM Storwize v7000) already have thin provisioning capabilities. The server will be a VMware virtual machine running Debian with RDM LUNs of 500GB. Data blocks will be automatically spread across several RAID disk (SSD, SAS, SATA) by the v7000. The «mdbox_rotate_size» will be configured around 10MB. Thanks, Nicolas C.

why would replicated to server ask for extra fs permissions?
by lejeczek 24 Jun '15

24 Jun '15

I think I'm near getting a simple replication, but on server which is still "empty" I get: Initialization failed: Namespace '': mkdir(/var/spool/mail/ccnr.biotechnology/nr412/Maildir) failed: Permission denied (euid=1187(nr412) egid=513(Domain Users) missing +w perm: /var/spool/mail, we're not in group 12(mail), dir owned by 0:12 mode=0775 but repl from server runs just fine and their configs are virtually identical. What I missed? many thanks

is it safe to have two backed used for the same user?
by lejeczek 24 Jun '15

24 Jun '15

hi everybody I wonder if it is safe (and wise) to have two passw-user databases for the same one user. I'm thinking, mail to me via pam mail to me(a)this.domain via ldap whole Maildir would be essentially the same one storage target, I see permissions have to be mangled, available to write for both vmail and actual uid. what do you think? Is it how it's done? regards

Quota question

http://wiki2.dovecot.org/Quota/Configuration says: concat('*:bytes=', quota_limit_bytes) AS quota_rule and concat('*:bytes=', quota_limit_bytes) AS userdb_quota_rule but a generic quota_rule on the same page says: plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M } Are "bytes=" and "storage=" equivalent? http://wiki2.dovecot.org/UserDatabase/ExtraFields also shows "storage=": user_query = SELECT home, uid, gid, \ '*:storage=100M' as quota_rule, mail_plugins, \ 'gz' as `plugin/zlib_save` FROM users WHERE userid = '%u' -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Assert test not compatible with s390(x) and ppc64 architectures
by Michal Hlavinka 23 Jun '15

23 Jun '15

Hi, we have found that assert test fails on some architectures: test-net.c:59: Assert failed: net_addr2ip("127.0.0.1", &ip) == 0 && ip.family == AF_INET && ip.u.ip4.s_addr == (127 | (1 << 24)) It seems as bug in test suit as test is expecting IPv4 address in LE format (0x0100007f), but it gets address in BE format(0x7f000001). Patch in attachment should fix this issue. Regards Michal Hlavinka

passdb pam and args/format
by lejeczek 23 Jun '15

23 Jun '15

I wonder if queries to/via pam are formatable? What I'm thinking I'd like to try is to use pam with users(a)local.domain. And I guess I'd have to loose domain part somehow. many thanks

a temporary failure
by lejeczek 23 Jun '15

23 Jun '15

dear all I have a postfix relaying to dovecot's lda but "strangely" it does not work, I mean I imaging it's me doing something wrong, yet I cannot figure out what. postfix logs: to=<me(a)my.domain>,orig_to=<root@localhost>, relay=dovecot, delay=39296, delays=39294/2.2/0/0.27, dsn=4.3.0, status=deferred (temporary failure) and dovecot logs no error, despite having debug to yes in couple of places, it shows: auth: Debug: master in: USER 1 me(a)my.domain service=lda auth-worker(25343): Debug: passwd(me(a)my.domain): lookup auth-worker(25343): passwd(me(a)my.domain): unknown user auth: Debug: ldap(me(a)my.domain): user search: base=ou=People,dc=my,dc=domain scope=subtree filter=(&(objectClass=person)(uid=me)) fields= auth: Debug: ldap(me(a)my.domain): result: objectClass=top,top,top,top, ... here goes the whole lot of ldap atrribs, and at the end: unused. For passdb & userdb in the configs I only configure ldap backed, nothing else. Ldap works, I can query it without failling. I believe it's very simple set up but I must be wrong somewhere. pass_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = uid=user=%n,userPassword=password user_attrs = =home=/var/spool/mail/%d/%n,=mail=maildir:/var/spool/mail/%d/%n/Maildir:INDEX=/var/spool/mail/%d/%n:CONTROL=/var/spool/mail/%d/%n user_filter = (&(objectClass=person)(uid=%n)) Any suggestions very appreciated. thanks
