Again from the logs in my first message the troubling entries are those that look like this: Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Error: link(/spool/mail/j/jerry/mail/INBOX/u.20423, /spool/mail/s/steve/mail/INBOX/.temp.1311791081.P12412Q2M989550.testmailserver.) failed: Permission denied Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): +1IXBeVXME58MAAARoVNxQ: msgid=<201107271824.p6RIOPa5020900 at backup.>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2011-07-27 11:24:41] lmtp seems to be attempting to write a link from one user's mail store to another user's mail store. This only happens on recipients that are not first on the recipient list. Best regards, -Boris PS - Apologies to the list if this mail produces an out of thread message as I posted the original message as a non-member (needing moderator approval) and I am now a member.

[Dovecot] want only usder in userfile/passfile and use to login user@domain
by Erik - versatel 28 Jul '11

28 Jul '11

After adding: auth_username_format=%Lu the %d domain is unfolleded correctly. (and not empty anymore) Maybe a good idee to make a remark in the text Virtual Users about that. I use: passdb: driver: passwd-file args: /etc/dovecot/vhosts/%d/etc/shadow userdb: driver: static args: uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u In the password-file (shadow) i have to add users in the form user@domain. I want to add users in the form user I have also tryed not a static userdb but a real one; see example Dynamic-passwd locations. To get this working i had to add mail-uid and mail-gid. But still it has the same form user@domain and not user Can anybody tell my how to get ride of the domain part in the passwd en userfile. I still want the user to login with user@domain Thanks.

Hi, I upgrade my server an I have dovecot 2.0.9 (on RedHat 6) and my user uses Thunderbird 5.0 (on Windows XP). I use authentication via LDAP (Windows server 2003 AD). When users use in password diacritic marks (ą,ć,ę,ł,ń,ó) authentication failed. For example when user test have password: Sierpieńłą*123 in log file item appears: localhost dovecot: auth: ldap(test,192.168.0.68): invalid credentials (given password : SierpieDB#005*123) What can I do? Thanks

[Dovecot] dovecot quota feature request
by Shing 28 Jul '11

28 Jul '11

Hi all, I'm going to implement before queue quota check with postfix to prevent bounce mail, the quota information is stored into mysql using dovecot quotadict, it would be nice that dovecot can have an option to switch the quota check with (used space < quota) instead of (used space+mail size < quota), so that i can write a simple sql statement to check_recipient_access to reject those mail, thanks. Shing

[Dovecot] Store quota on passwd-file?? Not work
by Sébastien FOURCADE 28 Jul '11

28 Jul '11

Hello all, I have installed Dovecot 1.2.15 and Postfix 2.7.1 on my Debian 6.This install no include MySQL, I prefer to store Password/User in a file... File /etc/dovecot/passwd contains :user2@domain.com:{CRAM-MD5}::::userdb_mail=maildir:~/Maildir userdb_quota_rule=*:bytes=300M File /etc/dovecot/users :user2@domain.com::3000:3000::/home/vmail/domain.com/user2/:/bin/false:: What is the correct syntax for my file to use a different per-user quota ? This example not work on my Dovecot :user2@domain.com:{CRAM-MD5}:3000:3000::/home/vmail/domain.com/user2::userdb_mail=maildir:~/Maildir userdb_quota_rule=*:storage=200Muser2@domain.com:{CRAM-MD5}:3000:3000::/home/vmail/domain.com/user2::userdb_quota_rule=*:bytes=200M Thx.

[Dovecot] set delay between pop3-logins
by tonjg 28 Jul '11

28 Jul '11

I'm using dovecot 1.1.8 on a raq4 server running centos 4.8 Is it possible to set a time delay between all dovecot pop3-logins? say 20 - 30 seconds for example? My reason is I want to thwart the constant login attempts from hackers hunting for an open relay. It's no good blocking the ip address because every hack attempt comes in from a different address. I'm the only user on the server so no-one else would be affected by such a delay. Thanks for any pointers -- View this message in context: http://old.nabble.com/set-delay-between-pop3-logins-tp32134037p32134037.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] lmtp multiple recipients fail
by flylordis flylordis 28 Jul '11

28 Jul '11

Hello, I am having a problem with the lmtp delivery of mail addressed to multiple recipients. The first recipient receives the mail correctly but the next recipients do not. ltmp apparently tries to create a link from the subsequent recipients' mail store to the first recipient mail store and fails. This returns 451 smtp codes to the sender which then resends at some later time. Please see below for users jerry, steve, and mary. The message to jerry gets written but not steve or mary: ul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: none: root=, index=, control=, inbox= Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Connect from 143.112.53.4 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: jerry home=/spool/mail/j/jerry system_groups_user=jerry uid=18738 gid=4025 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: steve home=/spool/mail/s/steve system_groups_user=steve uid=9838 gid=3011 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: mary home=/spool/mail/m/mary system_groups_user=mary uid=7007 gid=3011 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Effective uid=18738, gid=4025, home=/spool/mail/j/jerry Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: fs: root=/spool/mail/j/jerry/mail, index=, control=, inbox=/spool/mail/j/jerry/mail/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): +1IXBeVXME58MAAARoVNxQ: msgid=<201107271824.p6RIOPa5020900@backup.>: saved mail to INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Effective uid=9838, gid=3011, home=/spool/mail/s/steve Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: fs: root=/spool/mail/s/steve/mail, index=, control=, inbox=/spool/mail/s/steve/mail/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Error: link(/spool/mail/j/jerry/mail/INBOX/u.20423, /spool/mail/s/steve/mail/INBOX/.temp.1311791081.P12412Q2M989550.testmailserver.) failed: Permission denied Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): +1IXBeVXME58MAAARoVNxQ: msgid=<201107271824.p6RIOPa5020900@backup.>: save failed to INBOX: Internal error occurred.

Hi, I'm using Dovecot 1.2.15 on Debian. On some clients, at least KMail, some messages (especially older ones) appear twice in the message list of the client. This is really annoying. Can anyone give me a hint on how to solve this issue? -- Best Regards, Dominik Schulz

[Dovecot] DIsctionnary flat file format for shared mailboxes ?
by Frank Bonnet 28 Jul '11

Hello I would be grateful if someone could send an example of a dictionnary flat file used by the shared mailboxes feature, it has very few here so a flat file will be enough I think. Thank you
