[Dovecot] Migrating from Maildir to Maildir:LAYOUT=fs
by Rainer M Krug 27 Aug '13

27 Aug '13

Hi I have use dovecot together with offlineimap to download my gmail account on a single user computer and I have only one maildir (~/Maildir). As I switched to Mac, I would like to use spotlight to index my mails, which apparently does not work as they are in hidden directories (.directories). So I would like to change to LAYOUT=fs. Is there an easy way to migrate my email structure? I have several folders and subfolders, but a manual solution would be fine with me as well. My questions: 1) can I simply restructure the mailboxes and rename the folders / move them into the folders where I want them after changing the configuration of dovecot? 2) Is there an easy tool I can use for this for one mailbox which is doing it automatically? Thanks, Rainer -- Rainer M. Krug email: RMKrug<at>gmail<dot>com

[Dovecot] Developer docs?
by C. Mills 27 Aug '13

27 Aug '13

Hi, I'm looking to modify Dovecot slightly to add support for a custom feature. I've spent some time reading the code, and I've been wondering if there are any contributor/developer documents I've missed that would make getting up to speed easier. I've read much of the code, and most of the wiki, including the Design/* and /*Process pages. They give a good summary of some of the design decisions, but I don't see much other than that. The docs included in the tarball are just dumps of the wiki pages. I've browsed some of the list archives as well, without finding much to help me. Are there other resources I've missed? What I'm trying to do requires passing some additional information/state from the imap-login process (presumably through the master) to the imap mail process. Any pointers much appreciated! Thanks, C. -- ----------------------------------------------------------------------- C. Mills -----------------------------------------------------------------------

[Dovecot] Dovecot tuning for GFS2
by Andrea gabellini - SC 26 Aug '13

26 Aug '13

Hello, I'm deploing a new email cluster using Dovecot over GFS2. Actually I'm using courier over GFS. Actually I'm testing Dovecot with these parameters: mmap_disable = yes mail_fsync = always mail_nfs_storage = yes mail_nfs_index = yes lock_method = fcntl Are they correct? RedHat GFS support mmap, so is it better to enable it or leave it disabled? The documentation suggest the use of flock. What about it?

[Dovecot] A question of imap timeout exit
by 刘莹莹 26 Aug '13

26 Aug '13

hello: I have a question on imap process: if a client connect to dovecot like foxmail(version 10) , dovecot will start at least 3 imap processes , and these imap processes will online until client logout , if the client not logout ,the imap process will always online. this is similar to the long connection and imap's auto logout timer is not effect in this case. now I have two questions: 1: if there are a large number of users online at the same time ( eg about 30 000 users): so dovecot should shart at least 30 000 * 3 imap processes, if user not logout ,so many processes are online all the time .this is terrible. I dot'n know if there is a solution ?? now I have changed the timeout = 2min and test ,dovecot active disconnected imap process ,but I don't think this is a appropriate option. 2: I want to know why auto logout timer duration of IMAP protocol must be not less than 30 minuters ?? My English is not vary good ,I'm sorry but I really want to know the answer . thanks
