Check your server's IP here

Email Blacklist Check - IP Blacklist Check - See if your server is blacklisted

mxtoolbox.com

what is /24 ?
you mean a CIDR block of IP addresses 1.2.3.0/24?
They all may be in the 'shit list'?

**added
in ssh or in terminal

$ host 1.2.3.4

#is there a proper server domain name returned?

DKIM SPF?

what is /24 ?

It's a hosting company I think. Server24

my ip is blocked and it returns a error code like "TSS09 permanently deferred"

This is usually related to unsolicited, bulk emailing. SPAM in the eyes of the recipient host. At Yahoo, and others, the typical response is:
[TSS09] All messages from XXX.XXX.XXX.XXX will be permanently deferred; Retrying will NOT succeed.

CIDR

WHAT??????????????????????????

Change the IP and try to warmup your IP before start sending emails

CIDR is the block system of IP allocation 0/24 /8 etc
/24 means 254 ipv4 +Broadcast

:~$ ipcalc 100.30.34.0/24
Address:   100.30.34.0          01100100.00011110.00100010. 00000000
Netmask:   255.255.255.0 = 24   11111111.11111111.11111111. 00000000
Wildcard:  0.0.0.255            00000000.00000000.00000000. 11111111
=>
Network:   100.30.34.0/24       01100100.00011110.00100010. 00000000
HostMin:   100.30.34.1          01100100.00011110.00100010. 00000001
HostMax:   100.30.34.254        01100100.00011110.00100010. 11111110
Broadcast: 100.30.34.255        01100100.00011110.00100010. 11111111
Hosts/Net: 254                   Class A

So the SMTP server is misconfigured or the IP being used (or the entire IP Block) is on the spam blacklists; Or,
Since the first few messages were accepted, either the content, or the rate of sending, caused the rejection as spam messages.

How was Gmail and MS Exchange Online/Outlook? Did you try those?

Then post it!

I need more details about the servers and the range of an IP address, so that maybe it can be useful to fix the issue!
