I’ll try that patch too and report to the list. Should it work even for lmtp (that is my favourite delivery method, for its scalability)? Andre

[Dovecot] User authentication fields size limit
by Andre Nathan 06 Oct '10

06 Oct '10

Hello I'm using authentication via SQL, and I'm storing the full mail_location in the database. This is a long string because we're using multiple partitions and hashing to create this path. It looks like this: # doveadm user andre=sneakymustard.com userdb: andre=sneakymustard.com password : $1$ixW87UeD$fLhORaJS0c5wNFmWqfJdI1 mail : mdbox:/var/spool/imap/partition7/11/andre=sneakymustard.com:INDEX=/var/lib/… quota_rule: *:bytes=1024M Depending on the user's email, this string can be even longer. What I've noticed is that it is truncated when it reaches 128 bytes. Could this size limit be increased? Thanks, Andre

[Dovecot] dovecot-2.0-pigeonhole-0.2.1 installation in wrong lib dir?
by Wolfgang.Friebel＠desy.de 06 Oct '10

06 Oct '10

I am building dovecot-2.0-pigeonhole-0.2.1 (dovecot-2.0.5, but that does not matter) with dovecot-config in place (in /usr/lib64/dovecot) on a 64bit Linux (RHEL5): ./configure --with-dovecot=/usr/lib64/dovecot The libs needed for several executables in libexec such as /usr/libexec/dovecot/managesieve-login are not installed in /usr/lib64 but in /usr/lib64/dovecot. Therefore the executable will fail to run: ldd /usr/libexec/dovecot/managesieve-login libdovecot-login.so.0 => not found libdovecot.so.0 => not found librt.so.1 => /lib64/librt.so.1 (0x00000032e9600000) libc.so.6 => /lib64/libc.so.6 (0x00000032e8200000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00000032e8e00000) /lib64/ld-linux-x86-64.so.2 (0x00000032e7e00000) To me this looks like a bug in the generated Makefile. I could easily fix that by providing the library path for the loader or by symlinks in /usr/lib64, but this is a workaround only. When doing the fix then managesieve works as expected (tested against my patched websieve using GSSAPI) -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] migration 1.2.5 -> 2.0.5 load increased dramatically
by Ralf Hildebrandt 06 Oct '10

06 Oct '10

During norml operation this morning we're seeing a significantly increased load on the IMAP server (factor 5, from 5 to 25). Does dovecot need to rebuild index files or perform other IO intensive operations after the upgrade? We're using Maildir Our monitoring shows increased "system" time. We're runnign fewer processes, the IO rate ist identical to yesterday, memory usage is identical. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Shared folder again !

Hello all, First of all sorry for this, it has been discussed many times, but i can not make it work. I tried for a long time now. I do something wrong, but i do not know what. First of all, i have virtual users, with virtual domains. Mail is stored in /usr/local/virtual/domain name/user So if my domain is domain.com and my e-mail address is johan(a)domain.com the directory is /usr/local/virtual/domain.com/johan i followed the wiki, and my configuration looks like the following. beasty dovecot # dovecot -n # 2.0.5: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.1-STABLE amd64 ufs auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes dict { acl = mysql:/usr/local/etc/dovecot/dovecot-dict-acl-sql.conf quotadict = mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf } disable_plaintext_auth = no first_valid_gid = 1004 first_valid_uid = 1004 last_valid_gid = 1004 last_valid_uid = 1004 log_timestamp = .%Y-%m-%d %H:%M:%S . mail_access_groups = vmail mail_debug = yes mail_gid = 1004 mail_location = maildir:/usr/local/virtual/%d/%n mail_uid = 1004 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_write_locks = fcntl namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { inbox = no list = children location = maildir:/usr/local/virtual/%%d/%%n/shared/:INDEX=/shared/%%n prefix = shared/%%d/%%u/ separator = / subscriptions = no type = shared } passdb { args = /usr/local/etc/dovecot/dovecot-mysql.conf driver = sql } plugin { acl = vfile acl_anyone = allow acl_shared_dict = proxy::acl autocreate = Trash autocreate2 = Junk autocreate3 = Sent autocreate4 = Drafts autocreate5 = Templates autosubscribe = Trash autosubscribe2 = Junk autosubscribe3 = Sent autosubscribe4 = Drafts autosubscribe5 = Templates quota = dict:::proxy::quotadict quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { inet_listener imap { address = 192.168.50.200 port = 143 } } service pop3-login { inet_listener pop3 { address = 192.168.50.200 port = 110 } } ssl = no userdb { args = /usr/local/etc/dovecot/dovecot-mysql.conf driver = sql } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_idle_notify_interval = 2 mins imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_plugins = quota imap_quota autocreate acl imap_acl mail_log notify } protocol pop3 { mail_plugins = quota trash pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master mail_plugins = quota acl mail_log notify postmaster_address = postmaster(a)test.com sendmail_path = /usr/local/sbin/sendmail } That is my config file.
