The ls in backticks is Useless. The sed and echo can be replaced with a variable substitution. Variables should be double-quoted although it doesn't really matter in this case if the example file names are representative.

Code:
for i in test.ghrt*; do
  mv "$i" mail."${i#test.}"
done

The expression ${var#subst} evaluates to the value of $var with the prefix subst removed (if matched). There are other similar operations for suffix substitution etc; see the shell's manual page or a tutorial for details.

if you have Python, here's a script you can use:
eg usage:
Code:
# ls -1 test.gh*
test.ghrt.part01.rar
test.ghrt.part02.rar

# filerenamer.py -p "test" -e "mail" -l "test.ghrt*" #use -l to list
==>>>>  [ /home/test.ghrt.part01.rar ]==>[ /home/mail.ghrt.part01.rar ]
==>>>>  [ /home/test.ghrt.part02.rar ]==>[ /home/mail.ghrt.part02.rar ]

# filerenamer.py -p "test" -e "mail"  "test.ghrt*" #remove -l to commit
/home/test.ghrt.part01.rar  is renamed to  /home/mail.ghrt.part01.rar
/home/test.ghrt.part02.rar  is renamed to  /home/mail.ghrt.part02.rar

# ls -1 test.gh*
/bin/ls: test.gh*: No such file or directory

# ls -1 mail.gh*
mail.ghrt.part01.rar
mail.ghrt.part02.rar
