[Rspamd-Users] How to stop spam before it is send out

[Marcus Biel]

Hi,

I am looking for a way to use rspamd (or any other tool) to check the
Emails send from our customers of maildroppa.com <http://maildroppa.com/>, using our api.

Email sending is done over an api - there is no SMTP server -
And there is not even a normal email, just a html message.
My idea is to somehow install rspamd on our servers and then again
Somehow magically let it check and rate our customers messages if or if not they
Are spam - and prevent sending them out in this case.

Any details if and how this would be possible?

Thanks in advance,

Marcus
