Hi,
rspamd is configured to block some files. Operation works perfectly. Is it possible to send a notification to the recipient of the email that the block has occurred?
Pop3 connector is used to collect mail.
not sure you can do something, with a normal use, email sent to your server, I think it is the normal behaviour, but here you send first to another email server, then you retrieve the email.
I think the original sender won’t have never a smtp rejection answer
