first_valid_uid
by Vince42 28 May '16

28 May '16

Hi, I have error log entries like dovecot: lmtp(22155, mail): Error: user mail: Mail access for users with UID 8 not permitted (see first_valid_uid in config file, uid from userdb lookup). This obviously tells me that the user mail (UID 8) is trying to access the LMTP daemon. How can I find out why he is doing so and how I can get rid of this error message? The mail system (Ubuntu 14.04 LTS : Postfix + Dovecot) is working - but probably not properly configured. -- Cheers, \\|// Vince (o o) ----------------------------ooO-(_)-Ooo------------------------- ''' (o)_(o) [ ][0][ ] ô¿ô (=°o°=) World Domination by Copy and Paste [ ][ ][0] - (")_(") [0][0][0] () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments Ooo. ---------------------------.ooO----( )------------------------- ( ) (_/ \_)

Unable to view shared mailbox
by dev 25 May '16

25 May '16

Hi All, I have a mailing list I'd like to archive and share with a handful of users. The users are all in OpenLDAP. 10-auth-system.conf.ext is setup with "driver=pam" so it appears anyone in LDAP who already is able to SSH into the server may also connect to dovecot with same username/password they use in LDAP. I have a shared mailbox directory called LISTS_Archive. The system directory is /home/shared_imap. I can connect to dovecot using LDAP credentials (using Thunderbird) and this shared folder (LISTS_Archive) is grayed out. I assume I have acls wrong? What I want is for users in LDAP to access the LISTS_Archive imap folder as a shared folder for everyone. Only R/O access however (which is 'lr' in acl file I think). Would someone please point out what I've missed? Thank you. # # egrep -v '(^$|\#)' /etc/dovecot/conf.d/10-mail.conf # mail_location = maildir:~/.maildir namespace inbox { type = private separator = / inbox = yes } mail_plugins = acl plugin { acl = vfile:/etc/dovecot/acls } namespace { hidden = no inbox = no location = maildir:/home/shared_imap/:INDEX=~/Maildir/shared/%%u:INDEXPVT=~/Maildir/shared/%%u prefix = LISTS_Archive/ separator = / type = public list = yes subscriptions = no } # # egrep -v '(^$|\#)' /etc/dovecot/conf.d/20-imap.conf # protocol imap { mail_plugins = $mail_plugins imap_acl } # # dir /home/shared_imap/ # total 8 drwxr-xr-x 7 root root 4096 May 25 10:26 .. -rw-rw-r-- 1 user384 mail-user 0 May 25 10:43 dovecot-acl-list drwxrwsr-x 2 root mail-user 4096 May 25 10:43 . # # cat /etc/dovecot/acls # * user=user384 lr

ot: selfcert IMAP StartTLS 143 Win10 Tbird woes
by voytek＠sbt.net.au 25 May '16

25 May '16

I was trying to set up a replacement laptop running W10/64 to replace a Win7 laptop, installed TBird, and, attempted normal setup: IMAP StartTLS 143, SMTP StartTLS 587 (like on old laptop), and, to cut a long story, eventually discovered it won't work till I changed IMAP SSL/TLS 993 ? SMTP seems OK, only IMAP didn't (I recall earlier similar type of issues with either Outlook or OE or WLive?) is this the self certified part ? or what is it ? what's the best way around ? or just leave it as 993 ? thanks for any hints , pointers or even words of encouragement

Not all commands are included, unfortunately. Also, the list only shows commands that are available with doveadm as per configuration. Aki

Error: Filename keeps changing
by Ward Romp 24 May '16

24 May '16

Dear all, Two days ago, my ldap server (for authentication) crashed and I had to set up a new one. Everything works fine except the mailbox for one user (let's name him debugger). When I try to access his mail whatever way, dovecot complains about "Error: maildir_file_do(........): Filename keeps changing" For example, a command "doveadm copy -u debugger(a)boontje.net Archive mailbox Netspar" returns doveadm(debugger(a)boontje.net): Error: maildir_file_do(/var/mail/vmail/boontje.net/debugger/mail/Netspar/cur/14230…: Filename keeps changing doveadm(debugger(a)boontje.net): Error: Copying message UID 1 from 'Netspar' failed: Internal error occurred.

Accessing the mails via a mail client (Roundcube, Thunderbird, etc...) give the same error. Dovecot runs on a virtual machine and the mailboxes are stored via a CIFS-share on a NAS. I rebooted both machines, checked the filesystem (no errors), CIFS-share, directories and mail files are readable and writeable by dovecot user (vmail on the mail server). The mails are intact, cat <filename> shows the full mail. I'm baffled, any suggestions?

Growing number of dovecot processes
by John Oliver 24 May '16

24 May '16

OS is CentOS 6, dovecot-2.0.9-19 Just started using this server as a replacement for an old Debian server running an old dovecot. The number of dovecot processes just grows and grows until there are 100 concurrent login processes (we have maybe 40 or 50 users), and then nobody can log in any more. A reload resets, but the number of stuck processes climbs very quickly. We're authenticating against an OpenLDAP. Unfortunately, this system is not connected to the Internet so I cannot paste logs or output of commands. I've been Googling, but aren't hitting on the right phrase to describe this issue to uncover possible answers :-( If anyone can get me pointed in the right direction, I'd appreciate it. -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

No implicit INBOX with mailbox_list_index = yes?
by Karsten Heiken 23 May '16

23 May '16

Hello all, I am running a Dovecot Cluster (2.2.13 and 2.2.23 show the same behaviour) using dsync replication (as described here: http://wiki.dovecot.org/Replication) In addition to that I allow users to share mailboxes using IMAP ACLs. My problem is that I need to set "mail_shared_explicit_inbox = yes" if I want my users to see Inboxes of other users. If I leave mail_shared_explicit_inbox = no, then the user cannot see any Inboxes of other users: > * LIST (\Subscribed \UnMarked) "/" Sent > * LIST (\Subscribed \UnMarked) "/" Drafts > * LIST (\Subscribed) "/" INBOX When I set explicit_inbox = yes, then I can see the shared mailboxes: > * LIST (\Subscribed \UnMarked) "/" Sent > * LIST (\Subscribed \UnMarked) "/" Drafts > * LIST (\NonExistent) "/" shared > * LIST (\NonExistent) "/" shared/bob(a)luis.uni-hannover.de > * LIST (\Subscribed) "/" shared/bob(a)luis.uni-hannover.de/INBOX > * LIST (\Subscribed) "/" INBOX After some digging I found out that if I set mailbox_list_index = NO, then everything works even without explicit_inbox: > * LIST (\Subscribed) "/" Sent > * LIST (\Subscribed) "/" Drafts > * LIST (\NonExistent) "/" shared > * LIST (\Subscribed) "/" shared/bob(a)luis.uni-hannover.de > * LIST (\Subscribed) "/" INBOX Since we are migrating from Cyrus to Dovecot, our users are used to the behaviour of explicit_inbox = no, so I would like to keep it that way. I would simply leave mailbox_list_index disabled, but the comment states it is required for NOTIFY, which in turn is required by the rolling replication -- am I corrent? > # Mailbox list indexes can be used to optimize IMAP STATUS commands. They are > # also required for IMAP NOTIFY extension to be enabled. > # mailbox_list_index = yes What am I doing wrong or don't understand?

Dovecot-FTS:

We're running Dovecot with SOLR Lucene 5.5 and we have several errors like badMessage: 414 for HttpChannelOverHttp@5216da8e{r=0,c=false,a=IDLE,uri=-} 20.5.2016, 14:10:16 and URI is too large >8192 in our solr-logfile. I don't know if this is a problem in SOLR or in Dovecot, so I just bring it to your attention.
