Does EFA reject incoming emails at all?
Posted: 23 Jan 2023 09:43
I have recently switched from old version of EFA 3 to latest version of EFA 4. I did not do any migration, just started fresh with default installation.. Previously I would receive something like 2000 emails per day of which around 80% were spam and 20% were legitimate.
Now, the very first thing I noticed is that I am receving a lot fewer emails. Only around 1000 per day. At the same time users are not complaining that anything they expect to receive is not received, so all seems to be good. However, that doesn't explain why I am receiving a lot fewer spam emails. I have a feeling that some incoming emails are simply rejected and don't appear in "Recent Messages" dashboard. Particularly those where I have added IP subnets into "Blocklist". Since recently I started to add IP addresses in the form of X.X.X (i.e. omitting the last number, for example: 163.172.227 - in the hopes that this would block entire subnets used by spammers). And I noticed when attack is ongoing as soon as I add the subnet to Blocklist I stop receiving any spam emails sent from that subnet..
In EFA 3 it would show all blocked emails with black background (marked Blacklisted)... However it is suspicios why EFA 4 just don't show them at all the moment I add the IP subnet to blocklist..
Am I talking nonsense? Can someone confirm if those emails are rejected at the time of SMTP session/connection? As this is not the desirable behaviour at all,- I still need to see what is Blocklisted instead of rejecting it.
