Spamcop mail changes

Spamcop is shutting down it’s email service. While anyone could report spam using Spamcop, the system also provided users email addresses behind the Spamcop filters. This shut down should have no major impact on senders. Email addresses in use will still be accepting email, but that mail will simply be forwarded to another address, instead of users being able to access it through POP or IMAP.
The one problem some senders may have is IF they are solely authenticating through SPF and they are publishing a p=reject DMARC statement. This may result in some of the mail being rejected at the forwarding mail server, like AOL, Yahoo and other services respecting DMARC policy statements.
User forwarded mail will be coming from 68.232.142.20 (esa1.spamcop.iphmx.com) and 68.232.142.151 (esa2.spamcop.iphmx.com). If you don’t want to apply DMARC policy to known forwarded mail, those are the IPs to special case.
