550 SpamCop.net - Blocking List ( bl.spamcop.net ) :
Click the link and find that this server has been blacklisted 4 times in the last 3 months.
we are aware of the issue. It is due to misdirected bounces. The server is currently using a different outgoing IP. if you received a reject simply resend the email.
a misdirected bounce is when a spam hits a customer’s auto-forwarder and gets sent to a innocent email address.
We have a system that changes outgoing mail ips within 5 minutes of spamcop listing it, giving us time to sort the issue out with spamcop.
