Hi,

Very often I get similar messages in the logs, which are getting blocked:

Jul 31 16:00:44 srvmx01 postfix/smtpd[3426]: NOQUEUE: reject: RCPT from static-IP-address.net.encoline.de[IP Address]: 450 4.7.1 <gate.faseroptik>: Helo command rejected: Host not found; from=<user01@domain04.com> to=<sales@domain01.com> proto=ESMTP helo=<gate.domain01>

I have added domain04.com into /etc/postfix/helo_access.pcre like this:

/^domain04\.com$/         DUNNO

I have tried and:

/^domain04\.com$/         OK

I have added it with:

python wblist_admin.py --add --whitelist @domain04.com

But there is no effect.
All the messages from that domain continues to be blocked.

Can you please advised how to fix it?

Thanks in advance.

BR,
Stan

You need to place this rule BEFORE other rules in same file. First match rule wins.

Re: Helo command rejected Whitelist domain

Hi,

I did it and now the error has changed to:

Aug  7 08:42:50 srvmx01 postfix/smtpd[27990]: NOQUEUE: reject: RCPT from static-217-17-207-45.net.encoline.de[217.17.207.45]: 554 5.7.1 <static-217-17-207-45.net.encoline.de>: Helo command rejected: ACCESS DENIED. Your email was rejected because the sending mail server appears to be on a dynamic IP address that should not be doing direct mail delivery (217-17-207-45); from=<mark@faseroptik-jena.de> to=<sales@domain01.com> proto=ESMTP helo=<static-217-17-207-45.net.encoline.de>

I have added /^\static-217-17-207-45\.net\.encoline\.de$/ DUNNO

But there is no effect.

What I am doing wrong?

BR,
Stan
