If anything of value was to be obtained from e-mailing Volition... it would be asking for something actually insightful... say, a brief interview on the HLP, perhaps. In which, perhaps we might manage to get Mr. Kulas to sit down and have a conversation with a good interviewer/interviewers. I'd be curious to know what the original prompt for FS would say about our endeavors. An interview between Dan Wentz and Darius about "the music and times of FreeSpace" would be a good read, too.
The "fan-spam" is old news. Anyone who's just played FS or FS2 is curious about a sequel. But unless there's a glaicer in Hell somwhere, an "official" sequel is not going to happen any time soon. Of course you'll get a quaint, polite response from the developer's secretary. And the company's staff might even want to do a sequel... However, remember the job of that said secretary is to respond in kind to any inquiry, hopefully answer a question, and keep your hopes up. Organizations like to have a good set of fans. Who doesn't?
