Hello everyone, I am currently evaluating dovecot for our new email production servers (20k+ mailboxes) and found out something strange. I'm using those settings on Dovecot 2.2.4 (x86_64 / Slackware / compiled from sources) mdbox_rotate_size = 128M mdbox_rotate_interval = 1d mdbox_preallocate_space = yes with virtual users and location like : mail_location = mdbox:~/mdbox I don't think the remaining config is relevant but ask me if you need some other parts. Using test accounts for 2 weeks now I've figured that the 128M preallocated space is never 'hole punched" (to use...

...a message, then a nightly cronjob purges the mailbox (refcount=0) a new mdbox .m file is created!. So deleting a 1 k message from the mailbox of an user is a new 99 MB file to backup. Any hint about this? I am also using ext4 (rw,noatime,nodiratime,commit=15,data=writeback) and I have read about mdbox_preallocate_space. I will try it, any hint about this setup? This is not still in production, so I have no idea about IOPs and user concurrency, but I have several thousand users. *4? Compression with mdbox* I am reading about compression in mdbox (zlib/bzlib). I am starting with zlib, has anyone experience wi...

Hello, there's setting in my config file: mail_location = mdbox:/var/vmail/%Ld/%Ln:INDEX=/var/indexes/%Ld/%Ln mdbox_rotate_size = 1M mdbox_preallocate_space = yes mdbox_rotate_interval = 1d As I understand, this settings means that file which contains letters with refcount=0 will be rotated after 23:59 today. I remember letter ID and execute grep whith this one in storage directory. Letter was presented. After that, I removed letter over IMAP protoc...

Hi, How to tune the size of each "m.xxx" file in mdbox format , in order to optimize the ratio size/number of files ? (I can see for instance more than 100 000 files in one directory due to very large mailbox size) If such parameter exists, what is the typical value ? Thanks Joan
