You can encluse the %s in \" to insure its an argument and not a string 
passed to the shell
sprintf(buf, "mail \"%s\" < newbie_help.txt &", ch->email);

however it might be safer to fork() (i know i know fork is BAD) or have 
another program to send the mail, or write your own mailing routines as 
shelling will lag your players for a bit
