[Dovecot] Spaces removed from subjects in FETCH response
by Kenneth Porter 06 Oct '04

06 Oct '04

I'm using SpamAssassin to tag spam and prefix the spam score to the subject line. To make the scores sort properly in the client's message list, I pad the score with spaces to right-align it. It looks like dovecot-0.99.10.9-1.FC3.2 is frustrating this by stripping the excess spaces from the subject before reporting it in FETCH responses. Here's an actual subject line: Subject: (SPAM? 6.9) Urgent Response !! Note the multiple spaces before the "6.9". Here's the matching FETCH command and reply, as reported in Mulberry's IMAP.log (just the relevant message is shown here): A00035 FETCH 1507:1524 (FLAGS RFC822.SIZE UID INTERNALDATE ENVELOPE BODYSTRUCTURE) * 1517 FETCH (UID 1557 FLAGS (\Seen) INTERNALDATE "02-Oct-2004 12:24:40 -0700" RFC822.SIZE 6263 BODYSTRUCTURE (("text" "plain" ("charset" "us-ascii") NIL NIL "8bit" 1168 24 NIL ("inline" NIL) NIL)("message" "rfc822" ("x-spam-type" "original") NIL "original message before SpamAssassin" "8bit" 3855 ("Sat, 02 Oct 2004 13:52:28 -0400" "Urgent Response !!"

Thank you very much for your prompt reply and I hope you can forgive me to have erroneusly send the previous message directly to your address instead of the ML address.

But if the problem is in the password field can be connected to the crypted password stored in userPassword? I wrong to set *pass_attrs = uid,{SSHA}userPassword* in dovecot-ldap.conf? Piviul

[Dovecot] 'Connection dropped by imap-server' when doing searches in
by Mike Jakubik 05 Oct '04

05 Oct '04

Hi, It seems that on larger folders (32k emails) searching fails with the following error under squirrelmail 1.4.3a. (The server continues to work, as the hard drive stays on for a bit after the error is displayed) --- Search Results ERROR: ERROR : Connection dropped by imap-server. Query: SEARCH CHARSET ISO-8859-1 ALL SUBJECT {9} 5.3-BETA7 SUBJECT {9} available --- Oddly enough, when searching for just '5.3-BETA7' instead of '5.3-BETA7 available' the search completes OK. I can search with multiple strings on smaller (3k) folders however. Thanks.

[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
