Env call should be capitalised

Line 60 in 58b6511

$env = getenv('email');

Other getenv() calls are using EMAIL, does this need to be the same?

if its a problem, its been a problem since the package was initially created

Yup, its in the 'if $to is an array' catch so probably little used, but if capitalisation does effect env vars then I feel it should be corrected.
