Post by: venty on July 27, 2022, 08:36:56 AM

Hi,

I do not receive mail, it returns the following message to the sender:

<xxx@xxxxxx.com>: host mail.xxxxxx.com[11.11.11.11] said: 554 5.7.1
Service unavailable; Client host [194.153.145.99] blocked using
zen.spamhaus.org (in reply to RCPT TO command)

I haven't made any settings changes...

Thanks in advance!

I noticed today the same problem today.

We have multiple messages in log with:
554 5.7.1 Service unavailable; Client host [xxx.xxx.xxx.xxx] blocked using zen.spamhaus.org

When I check IP on spamhaus, some IP addresses aren't listed there.

Not sure if this is spamhaus problem or centos webpanel.
Only fast solution was to disable spamhaus in postfix i /etc/postfix/main.cf
