Urgent help needed!

[ÐÜíïò Á. <padam @ otenet . gr>]

I am managing a majordomo mailing list (Majorcool version 1,2,0) and I have
the following problem:
Every time someone posts a message to the list, all the list members receive
a blank message, from the owner
What should I check? Any help would be much appreciated.
