Zen Internet Support Forum

Indeed we do not have an SPF record for zen.co.uk. Our customers are free to send from their @zen.co.uk addresses from wherever, eg their workplace etc.

I've discussed at length previously on here why I don't believe SPF to be particularly useful so won't re-iterate. However, we do publish an '_spf.zen.co.uk' TXT record that lists our smarthosts (mailhost.zen.co.uk) and the two queuing hosts[0]. We don't at this time publish a record associated with the cPanel platform. I can't remember the syntax but you can 'include' the _spf.zen.co.uk record into your domain's SPF records.

Actually, I've just added a '_cp-spf.zen.co.uk' TXT record that refers to the auxilliary mail servers for the cPanel platform. So for your needs you can include _spf.zen.co.uk and _cp-spf.zen.co.uk in your record and include the cPanel server's own IP address. That ought to allow you to email from cPanel or our mailhost cluster.

Thanks very much for this Jerry, that meets my needs exactly!

If it's helpful to anyone in future, here is the record I've just added for my Zen cPanel hosted account,

v=spf1 a mx include:_spf.zen.co.uk include:_cp-spf.zen.co.uk -all

This allows mail to be sent from the cPanel host itself, any MX servers (perhaps they send non-delivery reports) and of course the records for Zen's main and cPanel mail servers. It then requests any non-matching mail is discarded, to help guard against my domain being used in the from: field of spam emails.

Thanks,

Tim

Excuse the multiple replies - if it's helpful I can confirm that with my SPF record in place, emails from my cPanel hosted domain are now successfully delivered to Hotmail recipients where before they were consistently marked as junk.

To help the process along, I submitted my domain to senderid@microsoft.com for inclusion in their "SIDF cache" as described here,
