I'll assume that 'email' is a file in the current working directory.  So
when  you open it and iterate through it, each line will be stored in
'user', including its trailing newline.

When you print 'user', you're seeing the newline.

To see for yourself, you could/should have used (just before your print
statement)

           print repr(user)

which will show such things as escape sequences.

Anyway, the easiest way to fix it would be to use rstrip() on the line.

for user in open("email"):
    user = user.rstrip()
    print '/opt/...

That's assuming there's no trailing whitespace that you DO want to preserve.
