notification emails blocked by spamhaus

Question

Hello, 
 I'm not receiving alerts from my UTM because spamhaus.org is blocking the email. I don't even know who that is; our email and spam services are provided by the same provider. Is spamhaus a free service used by the UTM? 
 How do I ensure I receive these alerts? I've already whitelisted the UTM's static IPs with our service provider. 
 Thanks, 
 Brian

You should configure UTM to submit mail to a mail server using authenticated SMTP on port 587 or 465. You can do this without changing your home connection, assuming that you have an email account that allows IMAP or POP connections. 
 You are being blocked because you have UTM Notifications acting as a mail server instead of acting as a mail user.

As a moderator, Brian, I can see the IP from which each post was made. Your IP is blacklisted on Spamhaus ZEN - I will guess that that's because you have a cable connection without a fixed IP. 
 If you have a dynamic IP, your service provider will need to do something else to allow email from your IP. 
 If you do have a fixed IP, you should ask Spamhaus to take you off their blacklist.
