Subject: [PATCH] send-email: move validation code below process_address_list

Move validation logic below processing of email address lists so that
email validation gets the proper email addresses.

This fixes email address validation errors when the optional
perl module Email::Valid is installed and multiple addresses are passed
in on a single to/cc argument like --to=foo@example.com,bar@example.com.
