Some years ago when my son had an AOL account, I had problems from time to 
time e-mailing him. It turned out that if there was loads of spam being 
allowed through by your ISP, and then turning up at AOL, AOL would block 
everything coming from your ISP until they did something about the spam.

Whether AOL are still doing that, I don't know, and your ISP is hardly likely 
to admit to you that they are being blocked by AOL because of spam.

It may be worth phoning your friend, and ask him/her to contact AOL, and ask 
if your ISP is being blocked.
