With Confluence server, 6.0, it seems you *might* be able to do incoming email handling for things like comments, and page creation.
There's a POP3 mail handler under General Settings / Mail, and there's a few interesting Email system addons, some are disabled.
I'm not able to find any real information on these settings. The online docs only refer to SMTP for outgoing email, and the addons have no mention at all.
I suspect this is either old, deprecated/broken functionality, or something that was never turned on.
I don't have email enabled at all on my test instance so it's not easy for me to test.
I'm curious if anyone's done anything with them and has any insight to share?
