Yes I have from both, but I don't normally use them. No sense in every site spamming me at those locations.
In fact I don't even check mail on my ISP account. Nothing in there but SPAM as I've never given it out to anyone or used it.
Just pointing out that there are people that just won't join your site if they can't use a free mail account, or unless you have something to offer that they really want and can't find somewhere else.
