Though I understand the reasoning. It's like "Dress like your ready to come to work and be promoted" and I do respect that. Though to delete it without even checking the resume inside? It would be like not even talking to the guy who showed up dressed nice but not suit and tying it. Let's be honest AOL has some stigmata but it's not like showing up to an interview in Flip Flops and a No Fat Chicks t-shirt
Maybe if your a person, looking to see if the place your applying for is a bunch of jerks, then go ahead and use that AOL address. They delete your email without reading it maybe you didn't want to work there. The filtering can work both ways.
Then again if your REALLY worried about this while job seeking. My advice is get an account on a domain you think would get you looked at. This doesn't cost THAT much *if anything at all* and then you can know you didn't get a call back because 7 years as Fry Chef at Burger Ranch doesn't qualify you to run a MySQL Database.
P.S. I know I could do stuff like, run a server on my own pop addy. I could use my ISP email. I know I could do a million other things but let's face it these big companies are not likely going anywhere and its an easy thing to do.
