Weird Email from [email protected] "Lagos, Nigeria"

I just got a weird email replying to a roommate needed near a college. Here's the message:
"--

including the time frame when it will be available.

I thought it was a little weird, and was worried about him trying to steal my email (it was anonymous through craigslist). I checked the X-Originating-IP: [41.190.2.180]. Quick search and this is Lagos, Nigeria . Doing a little more research and it looks like its a clear setup for a future scam. What should I do now?

Just ignore it. Thanks for coming here. Is there any more info for us ?

I just didn't reply to that one. I got another email that just said the first line of my Craigslist post with a "?" after it, and I think it originated from Brazil. It just said this: "I am moving out next semester and so I am looking for a sublease for the Spring and Summer?". Its from an Andria Tosten ([email protected]).

I received a 3rd asking for pictures again. Most people replying to this should 1: have a college email, and 2: want to meet in person to see the apartment. They again asked for pictures of the place, I gave them two and asked to schedule a time to meet if they wanted. Its [email protected] but the name says Laura Brooks. I couldn't track down the IP, but that one could be legitimate (The spelling actually looks normal).
