Well: I am working with Maildir mailstores, so I guess I need to have a uidlist kinda file then? Sorry it wasn't clear in my post that I am using Maildir style mailboxes...

So in a way, a lot of info COULD come from my database, if it isn't safe enough via nfs. Can you make all file locking configurable? Or will you do it on a "per-type" basis? (eg: mailbox locking, index locking, flag-file locking, etc). regards, Maikel Verheijen.

My dovecot is from cvs, updated yesterday, and running on Redhat 7.3 (if that matters). Here is my dovecot-pgsql.conf: --8<-- # # Postgress connect string.

[dovecot] INBOX at /var in maildir storage format
by Sebastian Pachuta 03 Apr '03

03 Apr '03

Hi I'm trying to figure out how to set default_mail_env to support such config: INBOX is in '/var/mail/%u/' (note last slash at the end, %u is an folder with new/tmp/cur subdirs - standard maildir structure). Other imap folders are stored as files (in mbox format) in direcotry '%h/Mail/'. Please advise.

[dovecot] Question about the password field in a postgresql database
by Maikel Verheijen 03 Apr '03

03 Apr '03

Hi List, When I try to set the default_pass_scheme in dovecot-pgsql.conf to CRYPT, the dovecot does not recognize my crypted passwords. If I prepend my encrypted passwords with {CRYPT}, dovecot DOES recognize it. (even when I set default_pass_scheme to PLAIN). Is this supposed to work, or am I misinterpreting things here? Thank you!

[dovecot] Failure in the presence of too many connections
by Mark E. Mallett 02 Apr '03

02 Apr '03

Had an event today where dovecot refused new connections and would not accept more until restarted, whereupon it worked for a few minutes and locked up again. Looking at the logs it appeared that it had run out of file descriptors. I increased the open files limit and started it again-- which worked but it only pushes off the problem. Does dovecot keep an open file descriptor for every imap or pop3 child? If so, this would argue more towards a tcpserver sort of control. If not, perhaps something is leaking.. -mm- PS: assume you saw recent RFCs 3501 and 3502 ?

[dovecot] NFS mounted IMAP dirs
by Maikel Verheijen 31 Mar '03

31 Mar '03

Hi list, I am trying to build an email system that is using multiple frontends, to a clustered backend using nfs. The backend mounts his filesystems from a central storage, and will be running active-active. While reading through the dovecot documentation, I read that I could do without indexes (well: use memory indexes), and could then be able to run dovecot over NFS. Well: that was until friday, when I was reading a little bit better through nfs.txt. :) My problem is now that dovecot writes it's subscriptions to the mailstore. Since I want as little difference between my frondends as possible, (and as static as possible), I would love to see dovecot handle subscriptions in a database, or perhaps a nfs-safe file. Since I am only a junior programmer (my code is really not far from "Hello world", although I am trying to find some time to teach myself more), I might not be able to be of much assistance to you all in coding stuff, but I am willing to help out where-ever possible. Can anyone help me solve my problem in any way, and how can I contribute as well? Thank you all, Maikel Verheijen.

[dovecot] FETCH BODY[part]<partial>
by Jesse Peterson 29 Mar '03

29 Mar '03

2003-03-24 12:59 Timo Sirainen <tss(a)iki.fi> This CVS update didn't actually seem to fix the problem. I still get the problem as before, like this capture: 10 UID FETCH 60 BODY.PEEK[]<8192.1915> * 60 FETCH (UID 60 BODY[]<8192> {1915} ) 10 OK Fetch completed. Not quite 1,915 bytes =). Perhaps the "[]" (without a part) is confusing it? But still, it grabs the first chunk correctly. At any rate, any input would be great.

[dovecot] Dovecot and Quotas
by Mike Machado 26 Mar '03

26 Mar '03

Is there anything that can be done so that when users IMAP to their inbox and have reached their filesystem quota, that they can still DELETE their mail? They can login, but when they go to delete/expunge this is the error I get in syslog. I have tried mail_read_mmaped to yes and no, and same result. Mar 25 14:54:27 penguin1 imap(bob): file_set_size() failed with index data file /home/bob/mail/.imap/INBOX/.imap.index.data: Disk quota exceededMar 25 14:54:27 penguin1 imap(bob): mmap_istream.madvise(): Function not implemented Mar 25 14:54:28 penguin1 last message repeated 65 times When using UW IMAP, sometimes users can delete mail and other times they cannot. I am desperately seeking a solution to have customers be able to delete their own mail when their box is full and not have to call our support center. Any suggestions? Thanks.
