We run a small corporate mail server. Recently, we have been sending mail
to a server, and the server always defers the mail with a 4xx code. This
has been going on for several days. So, should we continue to send it? Why
doesn't the server just reject it (5xx code)? This deferral is very
confusing to our administrators.

Common reasons for deferrals
- mailbox quota full
- you are blocklisted
- your (or their) DNS produces temporary errors
- others

does the deferral message explain why the deferral happens?
