[zope2-tracker] [Bug 965178] Re: MailHost overrides explicitly set 'From' header in the message text.

[Myroslav Opyr]

The change can potentially break some Gmail (or other MUA) filters that
relied on From header to be overwritten by send(). We'll update the patch
with version that has test corrected to take the changed behavior into
account. We'll possibly extend the dummy object to record envelope records
and will test if these envelope records are still correct.
