I'm planning on creating a new "backup" mail storage backend, where
you could basically run:
doveadm backup -u user@domain backup:
And it would output the user's messages to stdout (or to some file).
So it would be similar to e.g. PostgreSQL's pg_dump. Then for
restoring you can use the same input for "doveadm import". So in the
backups there would be no deduplication, unless implemented by the
backup software.
Hmmm, ok thanks... loss of dedupe on the backup server may or may not be
an issue I'll be concerned about, but good to know that there is an
option at least.
It looks like using mimedefang would eliminate the problem with
backups, and would provide the added benefit of eliminating large
file attachments for external recipients as well, however I'm
concerned about security - ie, how do you limit access to these
attachments to only the recipients of the message with the
hyperlink in it?
As long as the URL is random enough it shouldn't be possible to guess
the links. But if they're HTML mails and such then hyperlinks would
send the referrer-url to the next site. I guess you could also add
HTTP authentication.
Thanks for that too... I'll have to a bit of research on this, because
the more I think about it, the more I like the idea, *if* it can be done
securely enough...
