So you can "ping" the mail server from the AIX server. This only means you can send an ICMP packet. You need to know if you can do ESMTP/SMTP, e.g. TCP/IP to port 25.
So, try, can you manually connect (telnet) to port 25 (the smtp port) on the mail server, from the AIX system? Does it give you an smtp/esmtp greeting? Can you enter the EHLO or HELO command with your (AIX) hostname, and does it respond OK?
If so, then the problem may be in your code somewhere. If not, then for some reason which you'll have to determine (antispam configuration, reverse dns, etc.), the mail server is not accepting smtp connections from your AIX machine.
