AOL Blocking our mails

[JMT]

I run a site for a local youth athletic association. We had tryouts this last weekend for girls volleyball and notified the girls whether they made a team or not through e-mail.

Everything went fine until I started getting phone calls and emails on a hotmail account that AOL users were not getting their emails. It appears that AOL is blocking anything from our domain (eastview-evaa.org on Rasmus) regardless or whether I send it from EZMLM or from Outlook.

My question is:

What should/can I do about it?

Should I have the AOL users complain?
Can I complain?

This is a serious problem for us because we use email to communicate with our players and their parents. We save several numdred dollarsa per year on postage and reproduction costs.

Right now I have some unknown number of girls wondering but afraid to call.
