Reflexion should have a more robust notification system. For instance, if an incoming message is deferred for more than x minutes I should be notified. or if x number of incoming messages are deferred I should be able to send a notification. The list goes on.
The fact Reflexion is an important part of my client's ecosystem and isn't able to provide important data is very problematic.
Deferred messages should be alerted on.
Blacklisted IPs should be automatically checked (a subscription with MXtoolbox) so that Reflexion knows and takes action before our clients tell us there is a problem. This is a very high profile issue. We like Reflexion but if our clients can't send email because Reflexion is on a blacklist they will force us to change.
Reports on the good that Reflexion does for each user (Spam and viruses stopped). Scheduled delivery by email either to them or to us.
Global Filters for content blocking.
A way to add blocking to all clients in one window instead of making the same change to every client.
I do like the filtering before the junk even gets to our site, but please fix the black list issue.
