I have encountered a problem with subscribers having their incoming emails from a list blocked by spam filters, specifically because the server at the host university has been identified as a spammer. The host listserv then deletes the subscriber, because of consecutive bounces. I’m trying to ascertain how widespread the problem is: I only know of two specific cases, but I’m sure there must be more (the two cases I know of are at one university, but I am fairly sure that there should have been more subscribers there, and the filter is operated for many institutions by IBM).
Is there a way to identify subscribers who have been deleted from the list because of bounced messages in the past?
