Email addresses in thunderbird emails are not clickable.

Question

In Thunderbird V31.6, when viewing a received email which contains an email address (in the body of the message) that email address is not shown as a mailto: link, and is not clickable, so cannot be used to create a new mail message. This happens when View/Message Body As/Original HTML or View/Message Body As/Simple HTML. Mailto: links are displayed, and work, correctly when View/Message Body As/Plain Text -- but using this setting, other HTML links no longer display the target pages! (In this and other received emails.) Other email clients are able to display/action HTML links correctly and concurrently.
Can this be fixed, please? (I need to use View/Message Body As/Original HTML as my default setting, and not have to change it just to use an embedded mailto: link.

Thanks for your reply, Gnospen.
I have now realised that the received emails (with the unclickable email addresses) were from the same sender. They were created and sent from my mobile smart phone using an Android App called Type Mail (formerly know as Blue Mail) which I have recently begun using.
In Thunderbird, when I examined the message source, of emails sent from Type Mail, I saw the following (as an example -- substituting [square brackets] for <angle brackets> so that text does not get interpreted as HTML in this post)...
Content-Type: text/html;
charset=utf-8
Content-Transfer-Encoding: 8bit
[p dir="ltr"]Test new version[/p]
[p dir="ltr"][font color ="#006970"]Sent from a Mobile Device[/font][br]
[font color ="#006970"]Preferred Email: [/font][font color ="#006970"][b][email protected][/b][/font][font color ="#006970"][/font][/p]
...As you can see, there are no [HTML][HEAD], etc, [/HEAD][/HTML] tags to enclose the message text -- resulting in the message not being recognisable as an HTML message .
I will feed this back to Type Mail to see if they can fix it. If I read emails created/sent from Type Mail within Type Mail, they look as they should (with clickable email addresses), but this seems to be because Type Mail appears to apply its own formatting -- a bit like Thunderbird's View/Message Body As/Plain Text approach.
Thanks again for your reply and suggestion.
