Zen Internet Support Forum

Could someone please explain why we have suddenly started to receive these?

http://www.openspf.org/Why?id=gary%40mynton.com&ip=212.23.3.140&receiver=blade209.la.inty.net

We use Zen for outgoing email. I presume it is caused by the config at the recipients end?

 This is caused by having SPF setup on the mynton.com domain. SPF records designate which mailservers are allowed to send mail for a domain. If you wish to use our mail servers for SMTP you'd need to add SPF records for our servers to authorize them to do so. Without these records some mailservers (those that check for SPF records) will not allow mail to be delivered.

So do you mean I need to contact the host of the mynton.com mail server and ask them to enable this?

If your the host of the mynton.com mail server  has implemented SPF then they have probably also implemented an authenticated SMTP server, fo you to use for sending email.

That server will of course be mentioned in the SPF record so it won't create the problem you have been seeing.

The problem I have with that is that we were using mynton.com to send mail, but this was hosted on a shared server and it looks like someone, somewhere, was spamming, so we moved over to Zens.

Isn't there a way that we can continue using Zen's outgoing server and prevent getting mail kicked back? It is beginning to happen a lot more frequently now.

It is possible with the cooperation of the people who provide DNS for the zone mynton.com

 

Looking-up mynton.com in DNS currently gives

$ nslookup -Q=ANY mynton.com ns1.whatswanted.com
Server:         ns1.whatswanted.com
Address:        70.84.108.196#53

mynton.com      text = "v=spf1 a mx ptr ip4:70.84.108.196 a:ns1.whatswanted.com a:ns2.whatswanted.com-all"
mynton.com      mail exchanger = 0 mynton.com.
mynton.com
        origin = ns1.whatswanted.com
        mail addr = sysadmin.securewebz.com
        serial = 2008021701
        refresh = 14400
        retry = 7200
        expire = 3600000
        minimum = 86400
mynton.com      nameserver = ns1.whatswanted.com.
mynton.com      nameserver = ns2.whatswanted.com.
Name:   mynton.com
Address: 67.19.209.196

 

As you see there is a text record for spf that says mail from mynton.com comes from 70.84.108.196 (this is elendil.securewebz.com.).

You either need this text record deleted (which will disable SPF) or the text record changed to also include Zen's mailservers.
