Undelivered mail returned to sender
When I send a message to someone @codidact.com, I get back undelivered mail returned to sender, which says
<email@example.com>: host codidact-org.relay1g.spamh.com[126.96.36.199] said: 554 5.7.1 IP Block-listed globally (in reply to end of DATA command)
and whose attachment contains
Status: 5.7.1 Remote-MTA: dns; codidact-org.relay1g.spamh.com Diagnostic-Code: smtp; 554 5.7.1 IP Block-listed globally
This is not the full attachment since it contains private data, please let me know the best way to provide it if needed.
