Hi Zhang

I get the error message 554 5.7.1 when from some email accounts I am supposed to receive an email.
I searched the forum bit it seems that usually this error occurs when I am trying to send an email with my server, not to my server?

An example error message that a client of mine gets is:

__________

Your message:
  From:   user@clientserver.com
  Subject: Email

Could not be delivered because of

554 5.7.1 <mail.clientserver.local>: Helo command rejected: ACCESS DENIED. Your email was rejected because the sending mail server does not identify itself correctly (.local)

The following recipients were affected:
   my@emailaddress.com

__________

This is the corresponding /var/log/maillog:

Jan  5 09:00:24 contabo postfix/postscreen[19964]: CONNECT from [92.64.154.210]:12167 to [213.136.86.149]:25

Jan  5 09:00:25 contabo postfix/smtpd[19967]: disconnect from smtp-out.clientserver.com[xx.xx.xx.xx]



And this is another error message from a different client:

I have not altered anything to the original iRedmail settings in postfix

Can you help me with this?

Re: Error 554 5.7.1 - when some people try to send me an Email

Hi Zhang

Finally found this: http://www.iredmail.org/forum/topic8309 … eport.html

"The sender server is using a improper HELO identity during SMTP session, ".local" is not a valid top domain name.
You have two solutions:
1) Comment out this HELO restriction rule in /etc/postfix/helo_access.pcre. (search '.local' in this file)
2) Contact sender server administrator, and tell them they're using an improper HELO identity, ask them to use a proper one.
I suggest you choose 1) as temporary solution, solution 2) is the ideal one."


I already did 2).

I will also do 1) as a preliminary solution but I have one question:

Could I not get all of the emails with a bad helo into my junk folder instead of fully rejecting them and then whitelist them through my OSX client "Mark as not junk"?

That would be a convenient way forward, no?

In general it would be intersting to receive junk emails in my junk folder instead of blocking them completely. I only received 2 junk mail in the last month, which means my server basically blocks all of them. But I guess that needs to be another topic. let's solve the helo thing first ;-)

FQDN HELO identity is the basic requirement for a mail server, I think you're too kind to those spammers, or mail server administrators. let them die...

Hehe ;-)

Instead of 1) I tried the following, which I found on a previous thread:

Add this to helo_access.pcre as a whitelist for a specific server:
/^.*(mail\.clientserver\.local)/ OK Whitelisted

(from: http://www.iredmail.org/forum/topic6428 … tion.html)

I am not sure if this will work. My client has not sent a test email yet.
I wonder if it should be

/^.*(mail\.clientserver\.local)/ OK Whitelisted

or

/^(mail\.clientserver\.local)/ OK Whitelisted

actually.

Do you know?

This one should work, but do NOT use "OK" here, please use 'DUNNO' instead, so that the email will go through other restrictions. "OK" will bypass further restrictions.
