In the past 7 days, I have 145 emails from various vendors who are being flagged due to the sending IP address being found in Spamcop's blocking list. And 153 in the past 30 days. The IP's in question have varied, however the two that seem to be reoccurring are:
167.89.82.160
167.89.58.229 (this seems to possibly have been removed from the block list)
An additional one comes up as failing to retry when the email is deferred via greylisting:
167.89.58.138
None of these IP's are listed in Intuit's list of servers found here: https://quickbooks.intuit.com/learn-support/en-us/help-article/manage-customers/3-solutions-customer...
And this seems to have started on March 30th 2022 based on my email logs.
Since I'm not a customer, I don't have a direct line to support.
