There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
This is the exact error I am getting:
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<smtp.comcast.net #5.5.0 smtp;550-67.190.*.* blocked by ldap:ou=rblmx,dc=comcast,d c=net>
The problem is I can send email to some outside sites like my gmail account and some other ones but when I try to send to my work email address or comcast address I get the system failure. If someone could walk me through the steps on getting this fixed it would be worth 500 points to them.
Thank you.

Read the link that both Sembee and I posted. Sembee has provided the complete steps.

The destination server probably uses a list to block certain IP address ranges.
If you have a DSL connection to the internet then your IP address may be in this range. Most of these lists include DSL IP addresses because they may be in a range of known dynamic IP's. They feel that if someone has a dynamic IP they are more than likely to be a home based customer.
The way around this is to create an SMTPO connector to handle problem domains like this. The connector will be configured to deliver to a smarthost. The smarthost will be the SMTP server of your ISP.
