Is this a problem if one is using aliases as the comment above it implies:
	  /*
	   * KLUDGE ALERT - DANGER WILL ROBINSON
	   * We can't just leave a bare login name as the return address,
	   * or it will be alias-expanded.
	   * So we qualify it with the current host name (and, maybe, domain).
	   * Sigh.
	   */

	  if (chloc(buffer, '@') < 0
	   && chloc(buffer, '%') < 0
	   && chloc(buffer, '!') < 0)
	  {
#ifdef INTERNET
	    sprintf(buffer + strlen(buffer), "@%s", hostfullname);
#else
	    strcpy(buf, buffer);
	    sprintf(buffer, "%s!%s", hostname, buf);
#endif
	  }

Does this mean that if the local login name is the same as an alias it will
be expanded by the alias code?
