When the ActiveMail gets processed for encrypted messages
you will see messages/lines in the log as follows:
DEBUG: Detecting and processing ActiveMail of type(s) encrypted message
This means MNE is trying to verify if it is active mail and encrypted or not
and this is reported for every mail if you select "Migrate Active Mail".
There is a parameter however in the INI file that controls
what type of active mail to migrate:
It is configured primarily through MNE Wizard/UI.
The flags for this parameter can be assembled by adding together the values
for the types of Active Mail that is desired to be migrated.
Possible values are:
Encrypted mail 1
Stored forms 2
Rich markup 8
Messages with no "Form" field 16
Dropdown sections 32
if you want encrypted mail, stored forms, and dropdown sections the value would be 1 + 2 + 32 = 35
(note: the default value 31 is everything except dropdown sections)
There is however still a default value "Messages with no Form field 16".
This can not be selected through MNE Wizard/UI.
if you do not want to migrate "Messages with no Form " active mail
then you can edit the parameter as follows:
In this case, this setting will migrate only encrypted mails.
