Hello Zhang!

After migration of some customers from iRedMail to Office 365, we disabled some of their domains in iRedAdmin.

That customer has other email mailboxes still existend and in active use on that iRedMail server.

When that customer sends us messages, they receive following error message:

Apr 19 04:10:05 mail postfix/smtpd[28477]: NOQUEUE: reject: RCPT from mail-he1eur02lp0178.outbound.protection.outlook.com[213.199.180.178]: 554 5.7.1 <xxx@xxxxx.com>: Recipient address rejected: Policy rejection not logged in; from=<xxx@xxxxx.de> to=<xxx@xxxxx.com> proto=ESMTP helo=<EUR02-HE1-obe.outbound.protection.outlook.com>

Well, this is understandable but not desired.
Postfix checks for existance of the "from" address in the database and rejects the email.

There is no check performed to see if the whole domain xxxxx.de is disabled.

Is this a desired behaviour?

From a users point of view, if a domain is disabled (for administrative or other purposes), it should not cause these problems.
---OR---
Disabled domains may cause this problem, ok, but there must be a way to "archive" these domains.

Today the only solution I have to help that customer (actually enable him to send us email messages!) is to remove the whole domain from iRedAdmin.

Then all works as it should but there is no way to re-enable the domain or access the mail data for desaster-recovery or archive purposes.

So, what is the desired behaviour?
I don't know if we are hunting a bug or if we miss a feature

Best regards,

Bernhard
