Hello, list.
I'm asking question not directly connected with dovecot.
I'm planning a migration from cyrus-imapd to dovecot and i'm using cyrus2dovecot script (by Freie Universität Berlin) to convert mailboxes of users, but i'm wondering why size of mailbox in Maildir++ is so much bigger than mailbox in cyrus format after conversion: linux-a9qw:~/ # du -sh /mnt/imap/z/user/zinovik /srv/vmail/petrsu.ru/z/zinovik/Maildir 238M /mnt/imap/z/user/zinovik 1.2G /srv/vmail/mydom.ru/z/zinovik/Maildir
I was planning to implement quota for mailboxes about 1 gigabyte, but after conversion I would not be able to receive messages to my own box, because i'm overquota.
I think the only way would be to set quota up to 15 GB since some of users have mailbox with 12GB after conversion, but I have no such disk capacity to allow more than 1500 users have 15GB quota.
Would it be practical solution to compress all files after conversion and enable zlib support in dovecot?
