I'd installed rspamd as antispam in my postfix mail server.
Everything seems to work fine except for some users who report a
problem when trying to send e-mails from an external network. The
error is: An error occurred while sending mail. The mail server
responded: Try again later. Please check the message and try again.
I configured rspamd to disable greylist for email address coming from
our domain.
Where can I investigate to solve the problem?

I recomment using separate ports 587 or 465 (aka submission or
smtps/submissions) for authenticated relaying.
You can then configure separate rules on those ports.
However, the rest is up to rspamd configuration
