That's the point, it does NOT delete them. I have mine set up the same way and mine deletes the emails once they are downloaded, just like it is supposed to but for some reason my brothers does not even though it is set to do so.
I only use Linux so I'm not sure if it is a Mozilla thing, a windoze thing, a ISP thing or something else. I wouldn't think it was a Mozilla thing because it works on mine. Looks like if it was a Mozilla thing it would do the same on mine too. I use a local ISP, they use Linux too, so it may be a ISP thing. I'm just not sure what it is so I posted to see if anyone else has a idea.
They do delete emails a lot. Most of what they get is jokes and such. Once they read them, and maybe forward them on, they delete them.
I say we shoot it.
