Your IP's for "Added to UCEPROTECTL3 bryce-mx.dynu.com 107.161.27.201" and
"Spamhaus clark-mx.dynu.com 162.216.242.75" are on blacklists, and I'm using my neilwallace.com.au domain to send emails from a booksale system to advise people of their proceeds, so I need reliable deliverability. I only use port 587, and the system only sends email, not receives. Are you able to put me in a cleaner IP pool or remediate those IP's?

Thanks in anticipation
Neil
