Renaming SMTP server

[Robert]

Hello,
 Is there a way to rename my qmail server without damaging the current file
structure?  This is an excert from my maillog file:

Oct  6 03:16:00 mail qmail: 939197760.820006 new msg 310277

I'd like to change the name of that server if possible.  Is there a way to
do that?  I think I can recompile it, but I'm afraid of what that'll do to
the current directory structure.

Thank you,
Robert
