Hi George,
 
If we receive spam complaints from an organization like AOL, SpamCop or others, we must take action to warn the customer about these complaints so they do not continue to occur.  Our upstream provider will not allow us to host someone who receives continual spam complaints as this affects the entire IP network.  Because we do care about users having non-blacklisted email services, we must take action if we receive too many complaints for spam on any server.

If you have any specific complaints for your account, you can call or email us about this issue to discuss it with us so that we would be able to provide any personal details we might have on the complaint such as what email or what provider issued the complaint against the mailing.
 
Please let us know if you have other questions on this as well.
 
Thanks.
