 What the heck does the system name from either QWCRNETA or QWCRSSTS have
 to do with e-mail?  Are you confusing the system name with the TCP/IP
 domain name?


   Not I - I didn't write it.  I'm just stuck trying to clean up the mess.
   This is some kind of shareware/freeware stuff that developers at my
   employer obtained long before I arrived there.  The application composes a
   sender address for inclusion in a MIME file (to be processed by the
   QTmmSendMail) API in the format [1]username@xxxxxxxxxxxxxxxxxxxxxxx  It
   calls QWCRSSTS to obtain the system name.  All of these e-mails are sent
   internally.  The application is used to send spool files and/or data
   files; the data files might be sent as .xls or .csv.

   I have no interest in arguing the merits of the application design.  In
   fact, I hate the application and want to ditch it - it was cobbled
   together by developers who are no longer with the company, was never
   documented, so it's unsupported, and we have a commercial product that
   does the same functions and is fully supported by the vendor.  All I know
   is, the application used to work, when it came to retrieving the system
   name, and now it doesn't.

 To get the domain name for e-mail, you should use the gethostname() API
 documented here:

     In fact, this particular application doesn't have a compelling need for
     speed.  It's something from some shareware/freeware called TOOLKIT400, and
     it's an e-mail application that usually runs in batch, once per job.  The
     program calls the API to get the system name to form the domain part of
     the sender address.  The call to QWCRNETA (vs QWCRSSTS) is actually much
     faster.  A call to the mail send program can hang up for four to seven or
     eight seconds while it makes the call to QWCRSSTS, which doesn't even
     return the name (on this partition).  The call to QWCRNETA is virtually
     instantaneous, and it always returns the name.
