MX Record Lookup

I want a simple program that will use 20 winsocks. I want the program to not use DLL calls at all. The program should read a list of domains from a text file, query them for their mail servers, and write them to a listbox. The program must be able to handle large text files (more then 100 domains) without any problems and it must be very stable. All code will need to be commented or explained either in code with comments or in e-mails or messenger interactions. I want to learn as well. Thanks. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. Complete copyrights to all work purchased. ## Platform Win 9x and greater ## Deadline information Although the deadline is 4/28 I really need this ASAP.
