Ooof sorry David, I haven't had experience with that exactly. However I did have occasion to phone CallPlus once, and ask them to remove a client's static IP from their PBL. It was altogether an easy process: "Hi, one of my clients uses your broadband service, and they can't send outbound mail from their on-prem mail server." "Okay we'll just remove that IP from our PBL. It will take a few hours to replicate." ... that's it. It was a few years back now, but it was pretty straightforward.

Hi,

Has anyone had experience with configuring Postfix to allow inbound client SMTP connections from NZ-based IP addresses that have been Policy Block Listed (PBL'ed) by their ISP?

Spark have PBL'ed most or all of their home and small business fibre/*DSL connection IP addresses.

2degrees have PBL'ed most/all of their cellular data IP addresses.

I'm trying to support a user to send email from their cellphone email client.

Cheers

David

Isn’t this a matter of the smtpd_sender_restrictions config option? I assume you have an entry in there that is applying the Policy Block List; simply put another entry before that one, that allows the sender to connect based on other criteria. <http://www.postfix.org/postconf.5.html>
