- BM-Core is BlueMind's core component. It serves a a single management center for data and business rules. It is the only component that accesses the database.
All functionalities are exposed as Web Services and can therefore be driven by other applications.
All components, whether internal or external, use Web Services. This is useful for limiting incoming and outgoing BlueMind Mail flows (which are restricted to Web Services flows and mail flows) and ensuring the use of consistent management rules whatever the point of entry of a modification.

Estimating folder sizes
The usual size of some folders can be estimated:
~10% /var/spool/cyrus/data + /var/spool/bm-hsm
The size of the partition must be AT LEAST twice the volume of the data it contains.
Ideally, this folder should be deported and split into 2 dedicated partitions, which must meet the same size constraints:
|/var/spool/cyrus/meta||~10% /var/spool/cyrus/data + /var/spool/bm-hsm|
|Folder||Mount Type||Estimated Size|
These are mere estimates, which may vary depending on your install and your organization's evolution. We therefore recommend that you use technologies that enable you to increase the size of your file system easily.
Logs are written into subdirectories of the
|bm-lmtpd||LMTP service logs|
mapi service logs
For other components you may want to monitor, the following folders or sub-directories can be used:
|bm-php5-fpm/||FPM logs (/var/log/bm-php-fpm/ on RedHat)|
