This option license provides multi-domain feature.

Multi-Domain Feature

With this option, MailDepot can supprot multiple tenants (sites) in single server. MailDepot will create archive repository for each domain (tenant) independently. You can control each domain separately, and manage multiple domains safely in single server. This feature is suited for ISP/SaaS vendors.

Control the capacity limitation for earch domain

You can contole the capacity limitation for earch domain. If the limit is exceeded, mail archiving process will be stopped for the domain, and no more mail messages are archived for the domain.

Control the rate of importing process

To reduce system load (CPU and I/O load), MailDepot import archive mail messages with single process (not multiple processes) for all domains. To avoid long delay with bulk mails in some domain, MailDepot limits the rate of importing mail messages (maximum number of mail messages for single importing request). You can tune this behavior by changing "max_mail_import_num" parameter in configuration file. 

/opt/maildepot3/etc/maildepot.conf
"max_mail_import_num" is set to 1,000 at installation time.
max_mail_import_num = 1000
