[Dovecot] [BUG] Lucene plugin breaks header substring search
by Dave Abrahams 16 Oct '12

16 Oct '12

According to the IMAP spec if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. This behavior is present if I *even load* the lucene fts plugin. Note that lucene isn't in use (fts = squat); it's merely loaded. This behavior goes away if I don't load fts_lucene.

Re: [Dovecot] per-user quotas
by David Mehler 16 Oct '12

Hello, Thanks for your replies so far. Still having issues with per-user quotas. To my Mysql virtual_users table I've added a column quota_kb and for a test user I've added in a value of 250000 going for a 250 megabyte quota. I've tried various sql queries they're returning empty sets not pulling out the information needed. Thanks. Dave.

[Dovecot] fts = squat solr
by Dave Abrahams 16 Oct '12

16 Oct '12

I don't know if this was supposed to have changed with dovecot2, but http://wiki.dovecot.org/Plugins/FTS shows fts = squat solr so, since I have the lucene plugin—"fts = lucene" works by itself—I tried fts = squat lucene but: $ doveadm index '*' doveadm(dave): Error: fts: Failed to initialize backend 'squat lucene': Unknown backend So, is that syntax obsolete, is the wiki wrong, or am I doing something wrong? -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] POP UIDL
by simon.buongiorno＠gmail.com 16 Oct '12

16 Oct '12

Hi I run a small mail server with Dovecot and postfix. Several of the accounts are popped by an external email provide I use, mostly out habit and also for a bit of redundancy. I have no details on that external server except that it uses exim. Lately, it's been repopping mail from accounts (mail is left on the server so I can use IMAP) at fairly frequent, but undetermined, intervals. Before I take it to them, I want to be sure it's not an error on my side. How can I be sure Dovecot does not have a problem with the UIDL list causing this external server to repop the mail? For the record, I'm not inclined to think it's a Dovecot issue, but since that's the bit I can fix, I'd like to be sure. Cheers Simon

[Dovecot] Where'd the Mail Go?
by John Reddy 16 Oct '12

16 Oct '12

Hi; I ran this: echo "Hello me" | mail -s "Dovecot test" $USER then created a bash script: for mbox in /var/mail/$USER /var/spool/mail/$USER ~/mbox ~/mail/* ~/*; do grep -q "Dovecot test" $mbox && echo "mbox: $mbox" done grep -q "Dovecot test" ~/Maildir/new/* 2>/dev/null && echo "Maildir: ~/Maildir" and ran it but couldn't find where the mail went. I checked /var/mail/my_user_name and it wasn't there, either. How do I find it? TIA, John

[Dovecot] Advanced dovecot tricks - spam review/release
by Marc Perkel 16 Oct '12

16 Oct '12

Hi, I'm looking for some advice to do a really advanced trick with Dovecot. I'm not sure if this can be done. I need to describe first. I have a spam filtering company that does front end spam filtering. (Junk Email Filter) I want to add a system where I store a copy of spam on a server and make it available to the customer to review and maybe resent on false positives. I know I could do something simple where I deliver all spam to a domain account and make it available to an administrator. Then if it's a false positive they would drag the message to a "resend" folder. I'll have something the checks the folder one a minute to pick up and resend. However What would be very cool is delivering the spam to individual accounts. So a user who logs in individually can see their own spam. But the admin for the domain would be able to see all users. Maybe the users would appear as folders? Then a master account (me) would be able to log in and see all the domains as folders and the users as folders inside the domains? One thing I can do is deliver the spam to 3 different places so it's visible on all levels. I'm just wondering if anyone out there has any ideas about that. And I'll need an authentication system.
