IMail  as MTA will not modify sender addresses. However, any mail that
uses  IMail  as  MUA  (i.e, IMAIL1.EXE) will query the MailAddr value.
Note  that  ODBC  userbases are not subject to such restrictions, as a
user can be created with the short MailAddr from the get-go.

I  wouldn't  exactly  say  "nothing at all": if your computer name is,
say, GW02, and you try to send to [EMAIL PROTECTED], IMail will try to deliver
to  the  machine's  primary  IP  address even if GW02 is not listed in
IMail  as  a  local  host,  causing  either  a  mail  loop or a bounce
depending on relay config.

The  computer  name  + domain name together comprise the full computer
name,  subject  to  the  same  behavior. Note that under Windows 2000,
there is no distinction between a TCP/IP hostname and an MS Networking
hostname, since NetBIOS is now deprecated.
