Is it possible to get letters sent to the mailing address in MS Exchange?

Question

Email

For some time, the ability to receive mail to the mailing address from outside was disabled, so the recipients did not receive anything. But the mail went through the spam filter.
The question is, is she still there?

Answer 1

No. Users are likely to NDR, that they do not have rights to send to DL.
