How do I pick a web hosting service that has an email server that is not blacklisted? [more inside]
What do I do if a web site I maintain has been hacked? I've inherited maintenance of a web site, but I am mostly a front-end person, design and front end coding, so I am completely out of my depth here. Someone is using a user's identity to post hundreds of spam posts on the message board... really disgusting ones. The user has changed her password multiple times so I'm guessing they have another in. When I look at the database since they are both posting often (the real user and the spammers) I can't tell what IP address the spammers are posting from to block it. After that I'm lost... any suggestions?
I have an idea for yet another hairbrained social networking website (which paradoxically might hit it big :-) ). I've coded most of it up on a linux server using apache, php, mysql at softlayer.com.

I have a friend who cannot change ISPs or email services, he is paying a lot for dial-up time, and he gets about 100 spam: 1 valid email.

Despite plenty of googling, and even email with Microsoft's support - I cannot seem to solve my problem. I'm wondering if perhaps any of my fellow geeks have had this problem: I run a web/email server of my own, colocated in a highly reputable facility. For some reason, Hotmail views any email coming from my box as spam, and tosses it in a junk folder. I've done all the checks to make sure I don't have an open spam relay problem, etc. I've checked all the blacklists I can think of -- I'm not on any of them. [more inside]
