If a short story market doesn't say, how soon can you submit to them again? Is it different for acceptance vs. rejection? (For example, Clarkesworld Magazine says "Do not submit another story for a period of seven days after receiving a rejection" and "Writers whose work is accepted may not submit again until six months after their story is published." Is that sort of policy peculiar to their set-up?)

Specifically, a market has accepted a story by me that has not yet been published. Is it okay to submit another one to them? I'll probably e-mail the editor to ask about their policy, but is there a general guideline?
