[BlueOnyx:24510] Re: Problem with "Accept from unresolvable domains"

[Dirk Estenfeld]

Hello,

 

yes I did post about this two messages bevor you.

Please search in google for „outlook postfix Helo command rejected: need fully-qualified hostname“ and you will find some answers. The issue ist he postfix feature to reject mails from connections with a non fqdn HELO. And it seems that outlook (and maybe other email clients) do not send a fqdn HELO while communicating with the mailserver at port 25.

 

Check the checkbox "Accept from unresolvable domains" in Blueonyx GUI (Mail settings).

 

Best regards,

Dirk

Betreff: [BlueOnyx:24504] Problem with "Accept from unresolvable domains"

 

This new default is not working well.

 

I have users who ARE sending from fully qualified domains that are getting the error message and unable to send email with that box unchecked.

 

Here is an error message:

 

      'user at correctdomain.com <mailto:user at correctdomain.com> ' on 11/13/2020 8:57 AM
            504 5.5.2 <PMLT025>: Helo command rejected: need fully-qualified hostname

 

I have changed the email address above but it is a correct email address on a domain name that has proper DNS records for both www.correctdomain.com <http://www.correctdomain.com>  and correctdomain.com.

 

Thanks,
