Investigate spam filtering on mailbox.org

[JasonBarnabe]

Example headers for a confirmation email:

X-Spam-Flag: YES
X-Spam-Score: 16.011
X-Spam-Level: ****************
X-Spam-Status: Yes, score=16.011 tagged_above=2 required=6.31
    tests=[DKIM_SIGNED=0.1, DKIM_VALID=-0.1, DKIM_VALID_AU=-0.1,
    DKIM_VALID_EF=-0.1, HS_RSPAMD_20_21=9, HTML_MESSAGE=0.001,
    HTML_MIME_NO_HTML_TAG=0.377, MIME_HTML_ONLY=0.1, RCVD_IN_SBL_CSS=1.8,
    RCVD_IN_XBL=0.375, RCVD_IN_ZEN_LASTEXTERNAL=1, RDNS_NONE=0.793,
    SPF_HELO_NONE=0.001, SPF_PASS=-0.001, VFY_ACCT_NORDNS=2.765]
    autolearn=no autolearn_force=no

HTML_MIME_NO_HTML_TAG should be fixed by 40bade0693c56a76d8ddf79fd689a6c7c47a47e4.

VFY_ACCT_NORDNS may be due to the server identifying itself as localhost.localdomain instead of mail.greasyfork.org. I think I may have fixed this.

This seems to be normal operation of mailbox.org - first message is deferred for 10 minutes and then goes through successfully. http://projects.puremagic.com/greylisting/

So mailbox.org seems to be receiving emails from Greasy Fork - presumably this has been fixed by the changes above or stuff in #1199.
