Administrators • Occasional odd deferred error

Hello,
I'm running 8.8.15_GA_4717.FOSS with out issue... mostly. And my OS is Centos 7.9.2009.

Unsure when it started and for how long as I've been running Zimbra since v5.

But I'm seeing a deferred error on occasion and the emails do eventually go through.

The below error is in regards to a local domain to local domain error. By local domain I mean the domain that Zimbra is hosting email for.

But I've seen the deferred error between different domains.

So in this case it's basically userA@foo.bar to userB@foo.bar.

My error via the command;
/opt/zimbra/libexec/zmmsgtrace -r userA@foo.bar

Jan 9 11:54:12 - mail --> mail.foo.bar:7025 (10.0.10.246:7025) status deferred
(host mail.foo.bar[10.0.10.246] said: 451 4.0.0 Temporary message delivery failure try again (in reply to end of DATA command))

Has any one seen this and does any one have some tools to suggest that I can use to trouble shoot more?

* I've replaced my domain with foo.bar. And the mail server host name is simply mail.
