Topic: Helo command rejected: Go away, bad guy

Hello. One of the trusted senders cannot deliver the email. In logs:

Apr 11 15:05:16 mail postfix/smtpd[31332]: NOQUEUE: reject: RCPT from ns5.ediweb.eu[80.235.72.35]: 554 5.7.1 <ns5.ediweb.eu>: Helo command rejected: Go away, bad guy.; from=<do_not_reply@factorplat.ru> to=<buh@mycompany.ru> proto=ESMTP helo=<ns5.ediweb.eu>
Apr 11 15:05:16 mail postfix/smtpd[31332]: disconnect from ns5.ediweb.eu[80.235.72.35]

I added the file: /etc/postfix/whitelist inside which:
@ediweb.eu ok
@factorplat.ru ok

Then I executed the command:
postmap /etc/postfix/whitelist

and added a new line in: /etc/postfix/main.cf

smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/whitelist

and excuted:
postfix reload

But it didn't work, the letters are still blocked?!

Is 'ns5.ediweb.eu' blocked/listed in file /etc/postfix/helo_access.pcre?

No, but I found the following entry smile

/\.eu$/                       REJECT Go away, bad guy.

?

Please remove this line. It blocks all servers which send '<something>.eu' as HELO hostname. it's dangerous and i'm 100% sure it's a mistake.

YES, almost immediately deleted. Forgot that added this entry a year ago, because of the domain zone *.eu was a lot of spam. Thank you!
