Will SPF records work after migrating to Greenby?

[#1]

Will SPF records work after migrating to Greenby? If so, will they be the same? I cannot see a contact link for Greenby.

Here's the background. I currently have a few domains registered at Fasthosts. Some are used as email forwarders to Plusnet email accounts. I have the following SPF record at Fashosts and email seems to work well.

v=spf1 include:_spf-internal.plus.net include:_spf-internal2.plus.net ~all

Whilst I can move my own domains into some webspace that I have with another company, I will not have enough Add-on domains to move my aunt's domain there.

My options are to set up a mailbox at Fasthosts, move the domain somewhere else or use Greenby. Greenby seems to be the cheapest and preferred option. She still has Plusnet Broadband and my aunt wouldn't have to change any settings on her phone and tablet (I don't live near her).

Therefore, the only thing I need to know is whether the SPF record will still work.

Hi, I think you are up a blind alley with this matter. The actual chain here is; Tucows alias Enix  alias HostPresto! alias greenby.

Grrenby Ltd. have no mail servers and are just the front end. The fixers and is based in a private house. Your mail (If you transfer) is hosted by HostPresto! who presumably  as they host mail services also host domains, you would get perhaps a better answer by asking HostPresto!.

Lastly, I have no connection with Plusnet in any other capacity than being a broadband user.

I imagine the SPF subdomain will be updated Plusnet-side to incorporate the Greenby SMTP server IP’s.
