Spamhaus blacklisting mail servers on PlusNet IP range yet again

[#1]

Once again (couldn't reply to the thread, things moved around also so not sure but this might be the better forum as it's a techy issue for those of us running our own mail servers on static IP).

Following https://community.plus.net/t5/Business/Email-sent-are-being-rejected-as-SPAM/td-p/1463398

Again blacklisted, so some mail servers bounce my mail.

Requested removal of my IP again.

FYI for anyone hitting this, for now I'm changing to relaying through relay.plus.net, and as I have an SPF record on my domain I've set it to "v=spf1 include:madasafish.com -all"

Quick tests show this appears to be working and SPF validates on destination server (only tried Google and Hotmail addresses so far though).

Only problem with this is at least one PN mail server is on a blacklist.

Testing mail deliverability via mxtoolbox.com and it reports: avasout02.plus.net 212.159.14.17 - BACKSCATTERER
