You are obviously using Windows 64bit and it does not support 16 bit programs.  pconfig.exe is 16-bit.

To run 16-bit MSDOS programs on your 64-bit Windows systems (and Linux) get a copy of DOSBox. This is quite handy to have around when you have old MSDOS utilities to run.

You cannot edit the pmgate.sys directly, it's binary.  

I'm trying to set up Pegasus and Mercury.  When I try to send mail, I get a 501 error: domain literals are not allowed, with my email address expressed as user@[xxx.xxx.x.x], where the x's are my router's IP number (the domain literal).  I originally set up Mercury with this IP number as the "internet name for this system" in the Core Module Configuration: General tab, but then changed it to nnn.demon.co.uk (where nnn is our Demon hostname), which is what I think it should be.  I restarted Mercury, but it still seems to be forming addresses using the IP number.

I created the three local domain definitions as recommended in Mercury help, and one of them is our router IP number.  I think this is the only place within the Mercury settings where this IP number is now recorded.

Does anyone know how to fix this problem with the outgoing mail?

Pegasus Mail creates the from address using the Mercury user defined gateway.  This is generated when you tell use Configuration | Pegasus Mail | Update configuration.

             Gateway name :  MERCURY
           *New mail path :
   Is ? a program to run? :  N
    *New mail search mask :
      *Outgoing mail path :  \\thomas\maxtor\MERCURY\QUEUE
   *Run for outgoing mail :
         *Filename format :  ~d~d.101
  Run to validate address :
    *Reply address format : ["~p" <~L~L~N@novell-tstephenson.com>                   ]
  Accepts SMTP addresses? :  Y
  Simple message headers? :  'Glue' headers
    UUEncode attachments? :  Y
          Burst messages? :  N    Gateway processes BCC? : N
      Strip gateway name? :  Y
  Force all mail through? :  Y

 Format Pegasus Mail should use to compose the 'From' field for the message. ~8 or ~n indicate where the name should be placed.

You can either update this or use pconfig.exe from the Pegasus Mail program directory and edit the Mercury UDG.  I prefer using a different UDG so that the users can use different e-mail addresses when using identities.

             Gateway name :  MERCURY
           *New mail path :
   Is ? a program to run? :  N
    *New mail search mask :
      *Outgoing mail path :  \\thomas\maxtor\MERCURY\QUEUE

    *Reply address format : ["~o" <~r>                   ]

 Format Pegasus Mail should use to compose the 'From' field for the message. ~8 or ~n indicate where the name should be placed.  The ~o allows high bit characters in the username, the ~r tells Pegasus Mail to use the Pegasus Mail Reply to address for the e-mail address.

I tried to run pconfig.exe and got the message "The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher." I'm running Windows 7, Pegasus Mail 4.52 and Mercury 4.73.  I looked for an alternative version of pconfig in the downloads, but couldn't find one. Can I edit pmgate.sys directly, or do I need pconfig?
