supply a first, last, and domain name -- and this script will run through common email patterns to find valid email addresses. worried about domains with catchalls & missing mx records? yeah we got that covered. $ python check.py eric cartman southpark.com

# install dependencies: sudo pip install validate_email pyDNS
# run it: python check.py robin hood gmail.com

# FYI, forwarding addresses (not catchalls) will report 'probably not valid'. that's all i've got right now.
