AdamCollett Posted February 20, 2019 Posted February 20, 2019 (edited) A very strange issue where any reply from a hotmail/outlook.com/live address doesn’t come through, no bounce backs, no errors, just never gets through. Direct messages work fine, it’s just replies. Using a Sophos mail appliance for spam which might be an issue. Also, some replies do get through, others don’t. Just wondering if anyone else has seen a similar issue and might suggest where to start digging? Edited February 20, 2019 by AdamCollett
