Thank for clean my doubt about cyrus' storing folders. Restructuring setup ---------------------------------- Hardware: Pentium III 1.4Ghz 256 RAM 40 GB HD-IDE Soft: CentOS 4.2 Postfix Cyrus-IMAPd Partitioning(in MB): / 1.000 /boot/ 100 swap 512 /tmp/ 500 /usr/ 5.000 /var/ 10.000 /var/spool/imap/ 22.888 Seems to be pretty organized this. What do you think?
