[Dovecot] dovecot-auth
by Piviul 05 Oct '04

05 Oct '04

Hi, I'm a new list member, I’m a not an English native speaking (so, please forgive any error you can find in this mail) and I'm trying to install Dovecot in Debian Woody. I've installed the Dovecot package from backports and I’m trying to configure it to get the credential authentication from an LDAP backend. This is the configuration process summary I’ve done; if you need some configuration file I can post it with great pleasure. In LDAP I’ve created the user cn=dovecot,ou=DSA,dc=flanet,dc=org, I’ve configured this user to have read access to the userPassword field in slapd.conf (the other parameter such as uid, directoryHome… can be read as anonymous), I’ve configured the dovecot-ldap.conf to bind using the “cn=dovecot,ou=DSA,dc=flanet,dc=org” and I set the *auth_userdb* and *auth_passdb* of dovecot.conf to *ldap /path/to/dovecot-ldap.conf*. When I’m trying to start dovecot in the mail.err log file I can find > Oct 5 11:13:29 PDC-SMB dovecot-auth: LDAP: ldap_simple_bind_s() failed (dn cn=dovecot,ou=DSA,dc=flanet,dc=org): Invalid credentials Is the problem that the ldap-password is stored in SSHA crypted mode and in *dnpass* I've inserted it in plaintext? Or more in general, someone can help me to find where I wrong and how can I try to solve it? Piviul

[Dovecot] timeout when retrieving folder list w/ Evolution 2.0?
by leon breedt 05 Oct '04

05 Oct '04

hi, i have a problem with some maildir folders, where Evolution times out when retrieving the header list. It only happens with one particular folder, but i can't seem to find a pattern behind it. The amount of headers it does manage to retrieve varies, from between 3% to 50%. Its not a particularly large folder either (only 520 messages). The error message I get from Evolution is "Server response ended too soon". I did an Ethereal trace, and the closest IMAP command before the failure is: FLAGS (\Answered \Seen) RFC822.SIZE xxx INTERNALDATE "xxx" UID nnn)\r\n its a different UID value that fails each time though. after this response from the server, it seems to get through the message header (not sure if the entire message header was sent back). i'll keep this folder around as a test case. any ideas on where to start debugging? i'm fairly familiar with C and gdb. leon

[Dovecot] Dovecot and fcntl errors
by Eric Joe 05 Oct '04

05 Oct '04

Hello, I am new to the list and after searching the net for a solution to this problem, I have yet to find it. Maybe someone here can help. I had been using Dovecot that came with FC2 for about 1200 POP3 and IMAP mail accounts. At random times (1-5 days) an imap process would run the cpu usage up to 99% on one of my cpus (Running SMP P3-866) and hang. That process was unkillable and only a reboot would fix the problem. If I let it go, eventually it would lock up the server completely. I am seeing this error in my /var/log/maillog <snip> Oct 4 08:23:21 ns2 imap(editorial): Timeout while waiting for release of exclusive fcntl() lock for index file /home/editorial/mail/.imap/INBOX/.imap.index Oct 4 23:00:10 ns2 imap(jimar5573): Timeout while waiting for release of exclusive fcntl() lock for index file /home/jimar5573/mail/.imap/INBOX/.imap.index Oct 4 23:02:10 ns2 imap(jimar5573): Timeout while waiting for release of exclusive fcntl() lock for index file /home/jimar5573/mail/.imap/INBOX/.imap.index Oct 4 23:04:10 ns2 imap(jimar5573): Timeout while waiting for release of exclusive fcntl() lock for index file /home/jimar5573/mail/.imap/INBOX/.imap.index </snip> I have since upgrade (built from source) Dovecot 0.99.11 and have been running for 2 days without a hung process or lockup, but I still see these errors in the maillog. Can anyone suggest a fix? Regards Eric

[Dovecot] Dovecot/IMP Bug with RFC822.SIZE and BODYSTRUCTURE
by Ryan Hulsker 05 Oct '04

05 Oct '04

Ok, I have narrowed my IMP/Dovecot attachment problem down to what I think is a bug in Dovecot. The test that follow are performed on 0.99.11. When you download an attachment in IMP it uses the php function imap_fetchbody() which contacts the IMAP server and retrieves just the mime chunk you are looking for. It does this by first fetching some information about the email, and then grabs the specific chunk you are looking for in a second request. The first request looks like this. "FETCH 258 (ENVELOPE BODY.PEEK[HEADER.FIELDS (Path Message-ID Newsgroups Followup-To References)] BODYSTRUCTURE INTERNALDATE RFC822.SIZE FLAGS)" Dovecot responds properly on all parts of this request except for the BODYSTRUCTURE portion which gets returned as this. "BODYSTRUCTURE ("text" "plain" NIL NIL NIL "7bit" 0 0 NIL NIL NIL)" This causes the imap_fetchbody() funtion to freak out and not do the 2nd request, and it returns 0 bytes. If I manually try "FETCH 258 (BODYSTRUCTURE)" Dovecot returns the expected data properly. I figured there must be an interaction between the BODYSTRUCTURE fetch and one of the other items that are requested, so I tried them all and narrowed it down to this. FETCH 258 (BODYSTRUCTURE) <- works OK FETCH 258 (BODYSTRUCTURE RFC822.SIZE) <- BODYSTRUCTURE reply is wrong. I have been surfing through the dovecot source looking for a way to fix or work around this, but I am only a mediocre C coder. Can anyone enlighten me? Ryan Hulsker

[Dovecot] trouble accessing mbox folders with simultaneous logins
by 2 m＠le / Jonathan Salomon 04 Oct '04

04 Oct '04

Hi all! I have setup dovecot (RPM) on a Fedora Core 2 machine using LDAP for authentication. It all seems to work pretty well, except for simultaneous logins. I am using mbox files to store the mail as follows (from /etc/dovecot.conf): default_mail_env = mbox:~/.mail/:INBOX=/var/mail/%u:INDEX=MEMORY So the INBOX file is stored in /var/mail, other mailfolders are stored in the users home directory in the .mail folder. Because the /home directory of this machine is mounted from fileserver through NFS, I have set the INDEX=MEMORY options (see http://www.dovecot.org/doc/nfs.txt) As said before I am getting some problems when using simultaneous logins for the same mail account (for instance when multiple users that work on a specific project want to share a mail account containing all the mail about the project in addition to their private account). The client used is Microsoft Outlook and besides some outlook specific problems, it also gives these errors (translated from Dutch) when many users are simultaneously logged in to the same account: 'Your server reported that a UID does not comply with the IMAP standard, which signifies an error on the server.' 'The UID of a message is unexpectedly deleted. This signifies an error on the server.' I am not sure where to look... I assume a problem with the index files? Does NFS cause the problem? Will this be fixed if I switch to maildirs? I would be grateful for any tips on the subject!

Re: [Dovecot] trouble accessing mbox folders with simultaneous logins
by Michael Cosby 04 Oct '04

I can help you narrow the problem down a bit. I'm assuming you're using 1.0-test45 or 46, in which case I see the same problem using mbox, index files stored on disk and no NFS. I access my mail via pine and chatter email (an imap client for the palm). While I've not seen any errors that specifically say UID, the client for the palm will occasionally reload messages from a few days back thinking they're new, which eventually crashes the client when the count of mail it should be loading doesn't match what it actually got (the palm client's in beta, too :) ). I solved the problem by moving back to the 0.99 series, which other than performance issues works just fine for me. - Michael ------------------- In response to: Hi all!

[Dovecot] Slow squirrelmail login/IMAP CPU 80%
by rusecure＠rogers.com 04 Oct '04

04 Oct '04

I've been having a problem with Dovecot on Fedora Core 2 with SquirrelMail on the same system. When ever I login through SquirrelMail the imap process consumes around 80% of my CPU and the login takes forever (about 10 minutes). 1 Once I do manage to login, everything is fine and can even log out and back in without issue. Has anyone encountered this? Thanks, Nelson
