It really depends on why the mail filters are blocking the mail.  Do  
you see anything in your MTA logs that is useful?

You can improve your chances by doing things like making sure that  
all of the DNS checks that spam filters might run against your mail  
server succeed.  Having an SPF record for your mailserver might  
help.  But these are general sorts of answers.  Without details of  
who's blocking and why such vague help is the best anyone can offer.
