http://dovecot.org/releases/1.1/dovecot-1.1.1.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.1.tar.gz.sig Hopefully this release lives a bit longer than v1.1.0. - Maildir: When migrating from v1.0 with old format dovecot-uidlist files, Dovecot may have appended lines to it using the new format and later broken with "UID larger than next_uid" error.

[Dovecot] LDAP Auth
by Proskurin Kirill 03 Jul '08

03 Jul '08

Hello all. Im trying to configure Dovecot to auth at LDAP. Main idea what login = email of user. At dovecot-ldap: hosts = 127.0.0.1 dn = cn=root,dc=ForexClub dnpass = secret tls = no debug_level = 1 auth_bind = no ldap_version = 3 base = dc=Virtual-Domains,dc=ForexClub deref = never scope = subtree user_attrs = user_filter = (&(objectClass=mailUser)(mail=%u)) pass_attrs = mail=user,userPassword=password pass_filter = (&(objectClass=mailUser)(mail=%u)) default_pass_scheme = CRYPT And... all works fine. Im can connect and auth. But in logs with debug_level=1 im see this: As im think it is *not* good. As im understand he not found anythink. BUT it is auth and work... Whats wrong? dovecot: Jul 02 19:47:11 Info: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=172.16.1.19 rip=172.16.1.80 lport=143 rport=59553 dovecot: Jul 02 19:47:11 Info:

[Dovecot] 1.1 namespaces and message corruption
by Kyle Wheeler 02 Jul '08

02 Jul '08

Hello, I've been trying out the new dovecot's namespace support, and I'm having some issues moving messages between namespaces. Specifically, when I move some messages from a Maildir-based namespace to an mbox-based namespace, the message gets corrupted: its contents are removed, and an entirely empty message is added to the destination mailbox. This is 100% repeatable (some messages just *cannot* be copied intact). I have two namespaces, set up like so: namespace private { # Default separator = . hidden = no inbox = yes prefix = location = maildir:%h/Maildir } namespace private { separator = . hidden = no prefix = "INBOX.ArchiveTest." location = mbox:%h/Maildir/Archive } All I do is tell my client (mutt) to copy a message from a folder in the maildir namespace into a folder in the mbox namespace. Does anyone know what might be going wrong or how I can even debug this? No error messages of any kind are showing up in the dovecot log file, and the mail_debug setting doesn't seem to give me any useful information. Message corruption of this sort worries me... ~Kyle -- To sin by silence when they should protest makes cowards of men. -- Abraham Lincoln

Re: [Dovecot] Poor pop3 over nfs performance
by Mark Zealey 02 Jul '08

02 Jul '08

In case anyone else is experiencing this issue, using the following in a postlogin script is a reasonable workaround: if [[ ! -e "$HOME/.lastlogin_imap" && "$HOME/Maildir/dovecot.index.cache" -ot "$HOME/Maildir/new" && "$HOME/Maildir/dovecot-uidlist" -ot "$HOME/Maildir/new" ]]; then rm -f "$HOME/Maildir/dovecot.index.cache" fi (whenever a user logs in via imap we touch .lastlogin_imap, so we only kill the cache file if the user is pop3-only and both the cache and uidlist are older than the new directory).

[Dovecot] 'Book of IMAP' ?
by Bob Gustafson 02 Jul '08

02 Jul '08

Hi I am needing a bit more detail on IMAP protocol and setup possibilities (for an application in mind). I note that 'The Book of IMAP' has recently been published in English (May 08). It seems to be focused on Cyrus IMAP rather than Dovecot. Does anyone on the list have the book? Is the book's treatment of Cyrus IMAP much different from Dovecot? Thanks for any comments. Bob G

[Dovecot] Errors running imaptest with dovecot-1.1.1
by Joseba Torre 02 Jul '08

02 Jul '08

Hi, I've been trying some benchmarks to compare 1.0 vs 1.1 -this is the easiest way to explain the move to my boss-, so I've compiled dovecot 1.1 and imaptest-20080627 in my secondary machine running RHEL4, with homes in NFS, indeces in local files and control files also in NFS. Then I've created 100 new users imaptest001-imaptest100, and set the password paquitoelchocolatero to all of them. Then I run: imaptest user="imaptest%03d" pass=paquitoelchocolatero mbox=dovecot.mbox clients=50 secs=10 logout=0 seed=123 2> errores The output is normal (still haven't began with the benchmark), but the "errores" file -attached- is filled with lines like this: Error: UIVALIDITY changed: 1214910049 -> 1214910037 Error: imaptest071[19]: UID=8 INTERNALDATE changed 1214910065+120 -> 1214910042+120: * 1 FETCH (INTERNALDATE ...

[Dovecot] User changing password
by Mauricio Tavares 02 Jul '08

02 Jul '08

If users are checking their email using imap or pop, is there a way they can change their own passwords (so I can create a temporary one and let them change them to whatever they want) through, say, Thunderbird or whatever?

[Dovecot] Can't create subfolders when activating namespaces, e.g. private/public
by Torsten Krah 02 Jul '08

02 Jul '08

Hi, i am using hardy dovecot, 1.0.10. If i enable namespaces (the private and a public one) i am unable to create new subfolders in my private namespace, only top level folders works. There is nothing in the log about that error even if i set mail_debug = yes. If i comment out everything (no namespaces at all, implicit private one), it works again. Any hints whats going wrong, why is my client getting the message about not being able to create this subfolder? kinds regards Torsten
