SurgeMail implements several archiving models and you can pick
and choose the features you want.
The Primary/Recommended archiving module is called the 'Legal
Archive', this lets you configure SurgeMail to archive all
incoming and outgoing email for a period of 'n' years to either a
local storage array or to the Amazon S3 storage cloud. The
messages can be searched and extracted back to email at any time
by the administrator or the user (if enabled)
See Legal Archive for more details
In addition you may wish to schedule automatic deleting of
messages in users mail folders after a period of time. Or
automatic moving of messages after a period of time. This
can be done in Accounts/Lookup/Mailbox/Nightly rules, and can be
setup per user, domain or globally.
