It seems to be complaining that scn.ca is not a valid domain. Two likes above that it looks like they tried to lookup your address and failed : > 11/27/2001 11:18:34: [7452] remote connection from > (unknown)[216.174.133.2] They are probably only accepting mail from machines who's ip address they are able to perform a successful lookup against. I would suggest that you (or your ISP, depending on who is authoritative for your reverse DNS) add a record for 216.174.133.2 as a PTR to your mailserver name eg 216.174.133.2 PTR mail.bigstudios.com.
