Hi Adrain

Sorry, I didn't recieve the original post so if I've misunderstood the 
question please ignore me. (The fact that I didn't recieve it have 
nothing to do with you mail server ;P )

If your server is blacklisted as an open relay incoming mail shouldn't 
be blocked. However if you send email out to a client and thier ISP or 
Anti-spam software is making use of a blacklists (that you happen to be 
listed on) your mail may not reach them as your server is listed as a 
threat.

For example if you send an email to me and my anti-spam software/ISP is 
checking emails against a blacklist I shouldn't recieve your email.

This site basically checks against a bunch of lists and lets you know if 
your listed on the Internet or not, if you are on one go to the site and 
follow thier instructions on getting yourself off thier list. However 
you should ensure that your server is no longer an open relay as this 
will only get you into more trouble.

Good Luck

P.S. If you've been blacklisted by a private company and not an internet 
blacklist you would need to contact the company. However if you don't 
send mail to the company there shouldn't be a problem since they should 
be the only people not able to recieve you're emails.
