Help diagnosing mail delivery issue

    Hi folks,

    Wondering if I can get an opinion on this one...

    Connected from Eircom as ISP, I sent an email from my Google Apps email (Gmail servers) to a 3rd party at their own domain name.

    I got a delivery error message which looks like it came back from Hotmail, saying I should contact my ISP due to it being blacklisted.

    So, what I'd like to determine is whether the issue here is truly with the ISP (Eircom), or could it be Google Apps (afaics same as Gmail mail servers), or could it even be at the end where the recipient forwards the email from their domain to Hotmail?

    Here's the full error, with substituted email addresses (note I've used example.com and example.org to differentiate sender from recipient domains). My public facing IP 86.46.132.x doesn't appear anywhere, which leads me to rule out Eircom. So is the fault here that (some) Google Apps servers are blacklisted with Hotmail, or is it elsewhere?

    I think its more likely the case that their domain is forwarding to a hotmail address. The issue is that hotmail has blacklisted their (presumably) shared provider, which is common enough.
