there is a feature in O365 that forwards mails (in/out/both..) to an
archive-mailbox for long-term archiving.
We grab this mails via pop. However our available mail-readers
(Thunderbird, Kopano) show the original mail as attachment.
This is the „envelope wrapper“ format. It contains the _final_
recipient(s) of the email (eg after aliasing, distribution list
expansion etc), and contains the original email - headers and body -
unchanged. The advantage is that the archiving process does not need
to do any of the logic Exchange does (no further LDAP lookups etc).
Can someone donate a test message through pastebin? I would like to take
a look at one directly.
