Hi C,
Do you usually send email as your AOL or business address?
If you send email from your business address, use the outgoing mail server setting provided by your email hosting service, and only send email to people who really want your email, you should not have any problems unless your email service provider has a bad reputation.
Please send me an email from your business address too and I'll give that a check too.
There isn't much you can do you improve sending from AOL, it is what it is.
