Hi,

the sed command is a bit messy. You can also use a difference character
as a delimiter for the two fields like @. That would look like this:

  sed -e "s(a)usr/bin/sendmail(a)usr/bin/sendmail.postfix(a)g" ...

That makes it more readable.

You can also use the & character in the second half to get the matched
string from the first half. That would look like this:

  sed -e "s(a)usr/bin/sendmail@&.postfix@" ...

...which is even shorter.

I will merge this because you version is working, too.
