Postfix - Amavis erroneus SPAM

Deal, a software that control an hardware has to send alarm mail when
something happens. Starting from two weeks ago, the alarms stops to be
sent and checking in the mail server logs I see the following message:

Mar 12 09:03:57 mailserver amavis[14797]: (14797-01) Blocked SPAM
{DiscardedOpenRelay,Quarantined}, [150.217.XXX.XXX]:3685 [150.217.XXX.XXX] <mail@mydomain> ->

The alarms are blocked as SPAM.

Helo rejected


my user don't receive mail from a real sender cause our mail server
reject the Helo command:

NOQUEUE: reject: RCPT from[]: 450 4.7.1
<NTFYOHSrvNLES05.ntfy.local>: Helo command rejected: Host not found; from=< ... at xxx dot xxx.xx> to=< ... at xxx dot xxx.xx> proto=ESMTP
Nov 8 17:55:46 genio postfix/smtpd[3667]: disconnect from[] ehlo=1 mail=1
rcpt=0/1 rset=1 quit=1 commands=4/5

Is there a way to receive these mails?


Helo command rejected: Host not found

I'm trying to configure my outlook account to send email through my
mail server, but I receive the following error:

InvalidRecipientsException: Invalid recipients were provided for the
message: ' ... at cerm dot' (450 4.7.1
<HE1PR1001MB1369.EURPRD10.PROD.OUTLOOK.COM>: Helo command rejected:
Host not found

Is there a way to put * in a "white list"?
