Hello,

I've had our iredmail server up and running for a couple of days now and some of our regular contacts are getting blocked by the server. I've followed the info here:
https://docs.iredmail.org/manage.iredap … acklisting
and run the python scripts. I was able to add a few addresses and checked with python wblist_admin.py --list --whitelist and they show up. However the senders are still being blocked after a couple of hours.

Am I missing something here?

Thanks!

What's the original reject/error message in Postfix log file?

Zhang,

Thanks for the reply.

It looks like a HELO issue:

Jun 19 14:04:22 puffin postfix/smtpd[9139]: NOQUEUE: reject: RCPT from 50-201-36-42-static.hfc.comcastbusiness.net[50.201.36.42]: 450 4.7.1 <barracuda.krgenterprises.com>: Helo command rejected: Host not found; from=<gwaldman@krgenterprises.com> to=<jjrampsi@bkaarchs.com> proto=SMTP helo=<barracuda.krgenterprises.com>

I realize this means the sender's server is not configured correctly, but we get email from this consultant regularly.Does this require special handling?

Thanks.

Sure, just add a new line on top of file /etc/postfix/helo_access.pcre to whitelist it, like this:

/^barracuda\.krgenterprises\.com$/ DUNNO

Zhang,

Thanks much! But what does "DUNNO" do? It's not simply "OK"?

Re: Whitelisting not working

Oops, it's better use OK in HELO restriction rule HERE.

DUNNO will continue further exams, but OK will abort here and skip all further (HELO) exams.
