If you are trying to mail us for legitimate reasons and not trying to send SPAM, feel free to get an account at a free e-mail provider. We routinely block the networks where spam originates and if you are unfortunate enough to be hosted from inside one of those netblock, you've been made a victim of poor business practices and a willful neglect of illegal actions (in some jurisdictions). You have our pity, possibly or sympathy, but until spammers can be sued for each piece of unsolicited e-mail they send everywhere in the U.S., I'll keep blocking them. And if you're a company that sends unsolicited e-mail, please let me know ahead of time so I can block your network addresses, too. It'll save both of us a lot of time.
