[Dovecot] question about
by Michiel van Es 22 Jun '05

22 Jun '05

Hi, I am running Dovecot (dovecot-0.99.11-2.EL4.1 on centos 4) and we are switching from newer machines. I copied all usernames from /etc/passwd,/etc/group and /etc/shadow to the new machine. I do not want that every user has it's own /home/$user directory.. When I test my dovecot installation with a telnet 'servername' 110 user test pass test I get this error: ################################################################################ Jun 20 13:22:47 mx01 pop3(aaptest): mbox: Can't create root IMAP folder /home/aaptest/mail: Permission denied Jun 20 13:22:47 mx01 pop3(aaptest): MAIL environment missing and autodetection failed (home /home/aaptest) Jun 20 13:22:47 mx01 dovecot: child 3393 (pop3) returned error 89 ############################################################################## So I changed the MAIL environment to /var/spool/mail (using Sendmail and mbox) Now I get this error: ###############################################################################3 Jun 20 13:27:37 mx01 pop3-login: Login: aaptest [::ffff:10.101.3.37] Jun 20 13:27:37 mx01 pop3(aaptest): open(/var/spool/mail//inbox, O_CREAT) failed: Permission denied Jun 20 13:27:37 mx01 pop3(aaptest): mkdir_parents(/var/spool/mail//.imap/INBOX) failed: Permission denied ################################################################################# Wht is Dovecot trying to AUTOcreate IMAP folders? I do not want Dovecot to do this hence I tell Dovecot to serve only pop3 and pop3s: # imap imaps pop3 pop3s protocols = pop3 pop3s # IP or host address where to listen in for connections. It's not currently # possible to specify multiple addresses. "*" listens in all IPv4 interfaces. # "[::]" listens in all IPv6 interfaces, but may also listen in all IPv4 # interfaces depending on the operating system. You can specify ports with # "host:port". #imap_listen = [::] pop3_listen = [::] Does anyone know how I can dissable this IMAP-AUTOcreate behaviour? Thanks in advance. Michiel

[Dovecot] test73 not compiling with iconv?
by Sean Porter 22 Jun '05

22 Jun '05

I've recently upgraded from test53 to test73 from a source compile on FreeBSD 5.3, and am getting some [BADCHARSET] errors in 73 that I wasn't getting in 53 (specifically with Squirrelmail). When I run one of Squirrelmail's built-in filters, I get the following error: ERROR: Could not complete request. Query: SEARCH CHARSET ISO-8859-1 UNSEEN Subject {14} *****SPAM***** Reason Given: [BADCHARSET] Unknown charset Googling around, I found the admonition on the wiki about chrooted environments: http://wiki.dovecot.fi/moin.cgi/QuestionsAndAnswers#head- e146cada4e103a4a93a736998c64f23b1a8cd312 so I disabled all chroot directives in my config and ran as root, just to see if that was the error. No luck. When running configure with "./configure --with-mysql --with- storages=maildir --with-ssl=openssl", I noticed that I got this error regarding iconv: checking for iconv... no, consider installing GNU libiconv Oddly enough, I do have libiconv-1.9.2 installed in /usr/local: /usr/local/lib/libiconv.a /usr/local/lib/libiconv.so@ -> libiconv.so.3 /usr/local/lib/libiconv.so.3 /usr/local/include/iconv.h and an iconv -l shows support for the charset in question. I tried adding the prefix directive to configure: ./configure --with-mysql --with-storages=maildir --with-ssl=openssl -- with-libiconv-prefix=/usr/local and got the same message. I presume that 53 picked up iconv headers and libraries from LD_LIBRARY_PATH, and now 73 isn't getting it even set explicitly -- I see some ChangeLog entries for iconv files in dovecot source in May, but nothing more. How can I verify that dovecot compiled with libiconv support? Anyone else see the same thing? Thanks, Sean

[Dovecot] Hang-up problems with outlook 2003 and test 1.0
by Alfonso Sparano 21 Jun '05

21 Jun '05

Hi all, I'm testing dovecot 1.0 on a tru64 v5.1 and on a rhel3 platforms. I've a problem when I use outlook 2003 to download mails: outlook stop responding and hang-up when I use imap protocol. Someone have the same problem? What should I do? This is my configuration: protocols = pop3 imap disable_plaintext_auth = no mail_save_crlf = yes mail_read_mmaped = yes maildir_copy_with_hardlinks = yes protocol pop3 { pop3_uidl_format = %08Xv%08Xu } auth default { mechanisms = plain passdb = passwd userdb = passwd user = root } Alfonso

I guess you want to start with 1.0-test-reallybignumber as a base. If I had the energy, I might do this. P

[Dovecot] GSSAPI support status
by Fredrik Tolf 20 Jun '05

20 Jun '05

Hi list! I'm wondering, what is the current status of GSSAPI (krb5) support in Dovecot? I know from googling that there used to be a patch for it around a year ago, but I haven't seen a trace of that patch ever since, and GSSAPI doesn't even seem to be mentioned in the Dovecot source tree (at least not according to "grep -irl"). Is GSSAPI planned at all, as it stands? If not, is there a way for me to get my hands on the original patch, so that I can fix it up for the current version of Dovecot? I'm eagerly waiting for the day that I can switch from UW-IMAP to Dovecot, but I don't want to until I can get GSSAPI authentication. Thanks for reading! Fredrik Tolf

[Dovecot] "Angle" address with empty "display name"
by Chris Wakelin 20 Jun '05

20 Jun '05

Some clients are sending from addresses like <someone(a)somewhere.org> i.e. without a "friendly" name. It seems to me from RFC2822 that you should either have "Display Name <someone(a)somewhere.org>" or just "someone(a)somewhere.org" (both without the quotes). Dovecot, not unreasonably, treats "<someone(a)somewhere.org>" as having an empty Display Name, but this seems to confuse at least one client - our webmail ;) - which then displays "?" for the "from" address. The patch below tries to make dovecot treat empty display name as non-existent display name (so that the IMAP "ENVELOPE" command responds with "NIL" instead of "" in the relevant places).

[Dovecot] MySQL user_query ignored
by Helmut Zeilinger 20 Jun '05

20 Jun '05

Hi all, i installed Dovecot 0.99.14. Everything works fine except that the mysql setup directive "user_query" seems to be ignored - however the password_query works. Instead the default user query in db-mysql.c always takes effect. Might this be a bug or is something worng wit my setup below? (To keep on working i changed the default query in db-mysql.c..) Helmut dovecot-mysql.conf: db_host = localhost #db_port = 3306 db_unix_socket = /var/lib/mysql/mysql.sock db = mail db_user = mail db_passwd = db_client_flags = 0 default_pass_scheme = PLAIN password_query = SELECT password FROM users WHERE login = '%n' and domain='%d' user_query = SELECT '/var/mail/%d/%n' as home, 506 as uid, 100 as gid FROM users WHERE login = '%n' and domain='%d'

[Dovecot] dovecot.index.cache 1/3rd of INBOX size
by Chris Wakelin 17 Jun '05

17 Jun '05

I've noticed that my dovecot.index.cache file has got very large (24MB, which is more than 1/3 of my INBOX size). I've tried deleting (well, renaming) the dovecot.index.* files, and re-opening my INBOX, and the new dovecot.index.cache is only 90KB so far. I'm using dovecot-1.0-stable and mbox format. My mail_cache_fields and mail_never_cache_fields are set to the default. Looking back in the list archives, I found a message from Timo that suggested the cache entries are created for each message when the indexes are created, rather than when each message is accessed, so it ought not to grow? What happens when a message is deleted? I "strings/grep" ed through the dovecot.index.cache file and it looks like it's not caching any headers it shouldn't (like Received, X-Spam-XYZ etc.), but they seem to occur multiple times for each message. None of my other dovecot testers seem to have huge cache files (yet!). Anybody else seen this?
