The user database is set up because my clients, some bad users, send mass
mailings to non-existent accounts, such as hotmail, gmail, which usually
measure the number of IP bounces. Also sometimes there are cases where the
PC or mobile device is infected with a virus and they use the email account
to send spam, so I add those accounts that they sent to my list because
they can see spam trap. the database has maintenance, the accounts within
it are cleaned as I check them with another system, I only clean those that
exist.
here I add some info from the table

I would like to know if I can use mongo in the smtpd_recipient_restrictions
parameter anyway. Thank you.
