Symptoms
The issue started from Confluence 3.5 of which the "Share" feature was introduced and it affects both fresh and upgraded instances.

Either "Mail Page" or "Share" feature can work properly at a time.
Diagnosis
Scenario 1 (Fresh Installation)
Install a new Confluence 3.5.1.
Install Mail Page Plugin 1.12 and configure mail server.
Mailing a page in HTML format will work as normal but sharing a page will not. The shared page will be sent to mailbox but the title and content were not visible and the formatting seems like as if it was from mailing a page:
To make the "Share" feature to work, disable and enable again Mail Page Plugin or Share Plugin.
Sharing a page will then work but mailing a page in HTML format will not work. Send & Cancel buttons were not visible and the formatting seems to originates from Share function:
