main.communitynet.ca is barfing with the MAIL FROM line. 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 :

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.
Hope that helps.
