Wrong email construction for voicemail to email option in userportal

Howdy,

Email construction is wrong and leads to email clients to now read it OK.
Other problem I've found is, the "Date:" field if also wrong constructed, it should be full date specified with timezone.

Here's a full source of an email sent by the userportal option.
