[dovecot] Why can't hierarchy sep be changed?
by Timo Sirainen 07 Apr '03

>From: Charlie Brady <charlieb(a)e-smith.com> There's something wrong with manually accepting posts from non-subscribed addresses now, they're just left to queue directory for some reason.. Please try to keep the From-address the same as the subscribed one. > >From maildir-storage.c: > > ... > '.', /* hierarchy_sep - can't be changed */ > ... > > Why can't it be changed? Is this just for courier compatibility, or is > there a deeper reason why it can't be changed? Actually I'm going to change it to '/' to allow folders such as shared/timo.sirainen/mailbox. The directory names themselves will still contain '.' separator to stay compatible with Courier's Maildir++ format. So even though new IMAP separator will be '/', '.' still can't be used in mailbox names.

[dovecot] a few other problem
by Farkas Levente 07 Apr '03

07 Apr '03

hi, I still has a few other problem with dovecot and mozilla. - when I open mozilla mail I can only see the toplevel folders in the left handside folder list and when I close the imap folder and open it again (click on the arrow left to the imap server in the folder list) mozilla show me all folders and subfolders correctly (but not at the startup). it can be mozilla's bug, but this was worked when I use courier?! - when I'd like to sort the messages by thread than the thread is usualy ok, but I'd like to see the the different threads sorted by date (as it was while using couirer or cyrus) but now it seems to me random:-(( it's very anoying. my be it's mozilla fault again, but may be mozilla use server side thread support. - in OE6 when we only select headers only sometime some message "disappear"! which means we see in OE6 a red line over the message (as it would be deleted), but no one delete it (yes I know you don't belive me, I also don't belive our users, but once I saw it). just click on it to see the message and inmediately become as deleted. while when I look at in the server the file is still there and _not_ deleted. and OE6 show "the message already removed from the server". - what about the ssl (imaps) problem? yours. -- Levente "Si vis pacem para bellum!"

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.

[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 ?
