Adjust mail sending option

-e should be -E: Some mailx variants don't list -e, some silently seem
to map it to -E, some others use it to check if the local users mailbox
has some content, but -E (for those I've seen) always means what we want:
"Don't send a mail when there is no body".

Thanks to Neil Mayhew for reporting.
