Your main issue is that Transip sure do like to let spammers make use of many IPs within the /24 that you're in, we'll just need to flag yours as separate to prevent this from reoccurring. On Fri, 28 Jun 2024 at 10:19, Kasper Peeters via mailop wrote: > Is there anyone from Cloudmark on the list

Am guessing this resolved itself for you since I can see that over the past 24 hours over 97% of your traffic was happily accepted. I do see a not insignificant amount of mail to invalid recipients so you might want to check that you're understanding/processing bounces/deferrals properly. On Tue,
