Since I'm a Linux newbie and new to the LUG list, I hope I'm being too forward about this request. However, I have the possible oportunity to implement a Linux based "Bastion relay host" at work. This would be our fist linux box! We are investigating this solution since IIS has sooooo many security holes. I have done a fair amount of research online, unfortunately I am still not able to determine the best solution. It appears to be a rather complex undertaking, as this box would sit in the DMZ and thus would need to be very secure. It is required to perform only as a smtp relay host between Visi.com and our Exchange server behind the firewall. This is obviously beyond the scope of my abilities at this time. However, I'm hoping I could learn something from one of the LUG members willing to take on this project. And yes; YOU WILL GET PAID!!!. I work for WFTC TV (FOX29) as a broadcast engineer. We have about a month before we need to implement the host and the station will supply all the required hardware. Any experienced takers??? _________________________________________________________ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
