already talked to your VPS provider?
sometimes they block outgoing email

Since last Friday September 23rd I have the same problem.

I already configured another server, but it had the same problem. (I have the server at home)

Then rented a VPS and configured it in the same way and it doesn't have the problem.

The recipient will receive the following error message:

<test@domain.nl>: host mail.domain.nl[0.0.0.0] said: 554 5.7.1 Service
    unavailable; Client host [0.0.0.0] blocked using zen.spamhaus.org;
    Error: open resolver; https://www.spamhaus.org/returnc/pub/172.71.97.40 (in
    reply to RCPT TO command)

Checked IP address at Spamhaus, but was not listed. In addition, I have not installed Email => AntiSpam.
