Got a strange one I’d like to get to the bottom of. I use my "CatchAll" quite extensively for all different types of email testing as I look after my company mail system. I’ve testing a new outbound connector and have found an odd quirk. Mail sent from email@example.com to firstname.lastname@example.org is rejected as spam, but only for that recipient address. Any other recpiant address (e.g email@example.com, firstname.lastname@example.org or email@example.com) is delivered without issue from the same sender ID. I’ve checked my spam settings and can’t see anything listed to be blocked. I’ve attached the tracking report and screen shot of our hosted service (Mimecast) showing rejection from PlusNet. Any ideas?
