The following functions in MailArchiva require the ability to send out emails:
Not all of these functions may be needed in a given deployment, however at the very least, status reports should be enabled so that the system can be monitored for any irregularities. All the functions above require that an SMTP Client Connection is created in Configuration->Connections.
If the intention is to use the Send function above, the user specified in the SMTP Client Conneciton must be assigned the appropriate permissions to send on behalf of other users. For example, to do this in Microsoft Exchange, the following commands must be executed:
Add-ADPermission -Identity "MailArchiva" -User mailarchiva -AccessRights ExtendedRight -ExtendedRights "Send As"
