Mimecast automatically archives all inbound and outbound emails as they pass through the Mimecast cloud.  Mimecast can also be configured to capture internal emails between users (which normally would not traverse the internet). This is done using a process called Journaling.  In this way, internal email communication can also be added to the organization’s Mimecast Archive.

 

Records retention is a legal requirement for many businesses, which makes Archiving essential for email data.  Although the external email communications (inbound or outbound) for a business are automatically Archived based on the organization’s policies, internal email communication should also be retained.  This can be achieved through the use of a Journal connector, which facilitates the upload of internal email communication to Mimecast, so that it is stored in a single Archive.  It is then very simple to use Mimecast to search across all internal and external email data when required. Users are also able to search through all their emails in a single archive view.

 

 

How Does Journaling Work?

 

Journaling requires configuration in the customer environment and on Mimecast. Journaling needs to be enabled, which then allows the internal mail server to send a copy of all emails to a journal mailbox. Once Journaling is configured on Mimecast, all emails will periodically be delivered/retrieved using either SMTP or POP3 (or POP3S). These emails will then be archived in the customer’s Mimecast account, so that ultimately a full archive of all internal and external emails is available.

 

Depending on whether POP3 (POP3S) or SMTP is used, will cause a slight variation in how the emails are retrieved/delivered to Mimecast:

 

TypeDescription
SMTPThe customer’s mail server will deliver the journal messages to Mimecast using real-time SMTP push technology.
POP3Mimecast will regularly log into the journal mailbox and extract up to 100 emails at a time. At the time of logging out, if there are no more messages in the journal mailbox, Mimecast will wait a few minutes before re-connecting.
