When sending an email using 'Send as' or 'Send on Behalf' of a distribution group, emails do not get copied in the journal mailbox and are not getting archived.
- GFI Archiver
- Microsoft Exchange
Database level journaling in Microsoft Exchange does consider such emails.
If Microsoft Exchange 2010 RTM or SP1 is used, see A journal report is not sent to a journaling mailbox when you use journaling rules on distribution groups in an Exchange Server 2010 environment.
NOTE: Using "journal rules" requires enterprise licensing for Microsoft Exchange.
