[Dovecot] Maildir filename extensions S=<size> and W=<vsize>
by Ralf Hildebrandt 25 Oct '10

25 Oct '10

I'd like to add S=<size> and W=<vsize> to the filenames in my Maildir storage for newly delivered mails. But I cannot find where I can make Dovecot's LDA add those. Anybody? http://wiki2.dovecot.org/MailboxFormat/Maildir says: A maildir filename with those fields would look something like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S which is exactly what I want, but it doesn't tell me how! -- 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] fallocate and glibc 2.10
by Paul Howarth 25 Oct '10

25 Oct '10

In glibc 2.10 (32 bit) fallocate() exists but fallocate64() doesn't. When _FILE_OFFSET_BITS==64, fallocate() is a redirect to fallocate64() and the program can't be linked (fails to find symbol fallocate64). See http://bugzilla.redhat.com/500487 Attached patch detects fallocate() more robustly to guard against this problem. Cheers, Paul.

[Dovecot] "Maintenance instance"
by Ralf Hildebrandt 24 Oct '10

24 Oct '10

Does any of you have a "Maintenance instance" of dovecot? Something that will accept any user/pass combination (and thus doesn't make MUAs fail in utter unforeseen ways), and gives any user logging in a canned mail (e.g. "We're doing maintenance, go away") -- 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

24 Oct '10

Hi all, I have running dovecot-1.2.15 and I try whith dovecot-antispam-1.3 and 1.2-* if it's running for me. I use mailtrain backend to call a script when I move a mail to a specific folder. Then, I set allow_append_to_spam: yes At .config for Make dovecot-antispam. I set the plugin's name to: PLUGINNAME=isspam An then, I have another copy of the sources and .config with plugin's name set to: PLUGINNAME=nospam With this. If I put on dovecot.conf protocol imap { ... mail_plugins = isspam nospam ... } When I try to login, the connection is aborted and dovecot connection die with coredump Are there are any people with similar settings ? (doble instance of antispam plugin)

[Dovecot] [stava@telcotec.se: [stava: antispam problem]]
by Lars Stavholm 24 Oct '10

24 Oct '10

Hi All, I've built the dovecot-antispam-plugin from hg.dovecot.org and installed it. I've turned on debugging with "mail_debug = yes" in dovecot.conf and restarted dovecot. However, the antispam plugin module gets loaded by dovecot, but then nothing, i.e. when moving mail from Inbox to Spam and vice versa, I see nothing. How do I get debug messages from the dovecot-antispam-plugin? There's a few i_debug() statements in there (and I added a few myself), but I don't see any of these messages. # dovecot -n # 2.0.6: /etc/dovecot/dovecot.conf # OS: Linux 2.6.34.7-0.4-desktop x86_64 openSUSE 11.3 (x86_64) auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes base_dir = /var/run/dovecot disable_plaintext_auth = no dotlock_use_excl = yes listen = * mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Mail:LAYOUT=fs mail_plugins = autocreate quota zlib 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 passdb { args = /etc/dovecot/ldap.conf driver = ldap } plugin { antispam_backend = dspam antispam_dspam_binary = /usr/sbin/dspam antispam_signature = X-DSPAM-Signature antispam_spam = Spam antispam_trash = Trash autocreate = Spam autocreate2 = Sent autocreate3 = Trash autosubscribe = Spam autosubscribe2 = Sent autosubscribe3 = Trash quota = fs:disk quota quota2 = fs:user quota } protocols = imap ssl = no userdb { args = /etc/dovecot/ldap.conf driver = ldap } verbose_ssl = yes protocol imap { mail_plugins = autocreate quota zlib imap_quota imap_zlib antispam } Any help appreciated /Lars Stavholm

[Dovecot] minimize mbox mdbox fragmentation
by Stan Hoeppner 22 Oct '10

22 Oct '10

Hi Timo, Any chance the mbox/mdbox writer code could be modified to do physical preallocation on files to help avoid file(system) fragmentation? Constantly appending a file is the prime recipe for causing fragmentation, and mbox is notorious for this--not a fault of Dovecot but the nature of the mbox beast. Obviously maildir doesn't have such a problem, but some (many?) of us still prefer mbox for many reasons, fast full body search being one, portability being another. mdbox file fragmentation could benefit from such a change as well. I was having a discussion on the XFS list about this, trying to tweak XFS mount options to mitigate the fragmentation effects. Alas, there is no way to do this purely at the filesystem level. From Dave Chinner, one of the lead XFS devs: "What you want is _physical_ preallocation, not speculative preallocation. i.e. look up XFS_IOC_RESVSP or FIEMAP so your application does _permanent_ preallocate past EOF. Alternatively, the filesystem will avoid the truncation on close() if the file has the APPEND attribute set and the application is writing via O_APPEND... The filesystem cannot do everything for you. Sometimes the application has to help...." How great would the effort need to be to implement something like this? Would the return on investment be sufficient to justify doing this, in your eyes? -- Stan
