There should be a way of re-requesting it. You might want to try a different email account as some (I'm looking at you Hotmail) are very strict on where they will accept emails from. Hotmail will refuse any emails from my well-known hosting provider unless I jump through hoops to become trusted (no other company does this as far as I know). Back when I ran my own email server they did the same to me and even after their engineers verified everything they needed to and told me they lifted the block they still would not accept emails from my server.
