Using an email form on a site without mail active on domain

[timruns]

OK,
I have a client who we do webhosting/design for on a DotNetNuke site…
They handle their own email with inhouse servers. Mail is not activated on their hsphere account.
They want to be able to send emails via a form on their jodo-based, DNN website. Is there anything that would prevent this?

From my experience, the webservers do a fine job themselves sending email, although I seem to remember seing posts saying that feature was not reliable.

If they are using SPF, would it just be the webserver (eg web19) that we add to their SPF record?

Thanks

The only issue is that there is no rDNS record for webserver’s local SMTP.

Yes you need to add the webserver IP to their SPF record.
