[Dovecot] antispam for Dovecot 1.1
by Anders 26 Apr '08

26 Apr '08

Hi Johannes. I wanted to try out the antispam plugin for a Dovecot 1.1 install, only to learn that 1.1 is actually not supported. Are there any plans to remedy this? If not, is it known how much effort is required? (i.e. could I do it myself?). Thanks, Anders.

[Dovecot] Does a script exist to fix broken maildir timestamps?
by drbob 26 Apr '08

26 Apr '08

Hello, When I upgraded to dovecot (changing servers at the same time) in November last year I copied the maildirs from my old server without using the -p option to preserve timestamps! Since my mail client displays the email dates based on the Date header rather than the imap "internaldate" I didn't notice the problem until today when I tried to migrate an account to gmail using imapsync and found that all emails prior to November display the wrong date in the web interface (they show the date they were copied in November). I feel very silly. Before I go try to hack together a script which parses all my older email files and changes the timestamps to the time recorded in the "Date:" header, does anyone know if robust, tested version of such a script is alrady available? Would correcting the timestamps in this way cause any problems for dovecot (e.g in the index files)? Thanks in advance for any help. drbob NB In my googling for a solution to this problem I found this hack to imapsync which would rewrite the "internaldate" based on the date header during a sync. Whilst I'd rather fix the timestamps that are the source of the problem, it may be useful for others finding this post in the future, see: http://www.zimbra.com/forums/installation/237-received-date-appears-incorre…

[Dovecot] Mixing LDAP and static
by Anders 25 Apr '08

25 Apr '08

I want to read quota size from LDAP, but I have a static value for home. How can I mix these? Right now, I have this LDAP configuration: user_attrs = uid=home=/var/mail/vhosts/%d/%n,gosaMailQuota=quota_rule=*:bytes=%$M which works fine, but looks up the uid attribute needlessly, and is not scalable: I have to pick a different, always-existing LDAP attribute for each static extra field that I want to set. Is there some LDAP configuration syntax like the SQL "SELECT '/var/...' AS home" ? Thanks, Anders.

[Dovecot] 1.0.5: many pop3-login processes?
by Alan Ferrency 25 Apr '08

25 Apr '08

Hello, We are running dovecot 1.0.5 on a test server, with FreeBSD 6.2 (though I have noticed the same problem since dovecot versions in the 0.99 range). We don't have very many simultaneous pop/imap users, but we have a proliferation of pop3-login processes. Currently we have 128 such processes. We have 11 imap-login processes, but only a few actual imap processes running. Is this normal? Can we stop it? Is anyone else successfully running dovecot on FreeBSD 6.2? Thanks for your help.

[Dovecot] Problem with Dovecot Delivery Agent, Extra "From" lines and mbox
by Hokan 25 Apr '08

25 Apr '08

When an mbox email contains a line that looks like a "Mail" header it should be quoted (per RFC 4155). Sendmail's delivery agent does this, as does Procmail delivery agent. Dovecot deliver does not do this. Example line, with ">" quote: >From hokan(a)hokan.org Thu Mar 8 17:28:01 2008 When reading email (IMAP) that contains such an unquoted line, the email abruptly ends before the "Mail" line. There may (or may not) appear another email (visible to the client) that contains the rest of the email. -- Hokan MEnet, a wholly owned subsidiary of Enet System Administrator Department of Mechanical Engineering hokan(a)me.umn.edu Institute of Technology 612.626.9800 University of Minnesota

[Dovecot] Authentication: Dovecot -> Vpopmail - > MySQL with one table per domain
by James Nordstrom 25 Apr '08

25 Apr '08

Hi All, I am using Dovecot 1.0.13 with Vpopmail (Qmail Toaster current) backed by MySQL with one table per domain (--disable-many-domains) . What I cannot figure out is how to have Dovecot authenticate to Vpopmail when Vpopmail uses one table per domain. Basically I need dynamic SQL in the Dovecot-sql.conf file. Currently I have: password_query = select pw_clear_passwd as password from domainname_com where pw_name = '%n' I need something like password_query = select pw_clear_passwd as password from %d where pw_name = '%n' Where %d is the name of the table. I can't use the exact domain name at it will not match the vpopmail format domainname_com. I would be happy to use some sort of sting builder but and not sure what my options are in the .conf file. Please help Thanks in advance James James Nordstrom Nordstrom Design Inc. E-mail: james(a)nordstromdesign.com US: 908-419-5597 Europe: 001/908-419-5597

[Dovecot] Index maintenance
by Anders 25 Apr '08

25 Apr '08

Hi. I am unable to find information about what happens to the index file if I use something like the cron script at the bottom of http://wiki.dovecot.org/Plugins/Expire There must be some information in the index that is no longer needed. When and how will Dovecot clean this up? Thanks, Anders.

[Dovecot] sieve header :matches for multiline header
by Anton Yuzhaninov 25 Apr '08

25 Apr '08

RFC3028 say: Folding of long header lines (as described in [IMAIL] 3.4.8) is removed prior to interpretation of the data. The folding syntax (the CRLF that ends a line plus any leading whitespace at the beginning of the next line that indicates folding) are interpreted as if they were a single space. But it seems to be not true for dovecot-sieve-1.0.2 for header Received: from example.ru (example.ru [192.168.105.14]) by myserver (Postfix) with ESMTP id D4DA5D85927 This sieve test work: header :matches "Received" "from *by myserver (Postfix) with ESMTP id *" But this test not work, while should also work according to RFC: header :matches "Received" "from * by myserver (Postfix) with ESMTP id *" -- WBR, Anton Yuzhaninov

[Dovecot] ACLs generating plugin problems.
by "Fábio M. Catunda" 25 Apr '08

25 Apr '08

Hi! I'm trying to use an ACL to avoid deletion of messages that are inside .Trash folder, the ACL is already working very well, the problem that I'm facing is that even if the message is not deleted, mail_log logs that it has been deleted. Also, in some cases part of the lazy_expunge code is executed too, but sometimes I just dont know where the message is, thats weird. I erased deleted and expunged folders, then I deleted a message, It hasn't been deleted, but "deleted" and "expunged" folders has been created. Anyway, I would like to know if there is a way to stop plugin execution when an ACL matches. Thanks a lot.
