I need to see if it's possible to change the From address on email that is sent from our AIX 5.3 server.  We have an application that sends out email and the from address is "username@<servername>.domainname.com".  Is there a way in sendmail to change it so the from address is "username@domainname.com".  Also is their a way control the "username" part of the address?  If the process is run by "root" then the email come from "root@<servername>.domainname.com".

Your guestion is addressed by two Sendmail's FAQ entries:
  http://www.sendmail.org/faq/section3.html#3.2
    How do I rewrite my From: lines to read ``First_Last@My.Domain''' or ``Different_Name@My.Domain''?
  http://www.sendmail.org/faq/section3.html#3.1
    How do I make all my addresses appear to be from a single host?

Both redirect to http://www.sendmail.org/m4/masquerading.html

In short: use FEATURE(`genericstable ') with:
* FEATURE(`masquerade_envelope') if you  want to rewrite also envelope sender address
* FEATURE(`allmasquerade') if you want to rewrite also addresses in "recipient headers" (To:, Cc:)
By default sendmail rewrites *ONLY* "header sender" addresses
