I'm helping out a friend manage his website. Said friend has a domain, website.com, which I am transferring from his old host (OLD) to his new host (NEW), but OLD does not provide email services (or, at least, not intuitively). As a result, he wants both:
- To host the website at NEW
- To use the email servers at OLD so he can continue using the email accounts he set up there.
The move from OLD to NEW has taken place, and I have updated the DNS records so they no longer point at ns1.old.com, and now point instead at ns1.new.com, and so on.
But having searched around a bit for the solution to the email aspect, I'm a little uncertain. I've updated the MX record at NEW to point back to ns1.OLD.com, but emails are still failing - and I'm sure the reason for this is obvious, but I'm not quite grasping what I need to do here.
As I understand it, the process ought to be as follows:
- Mail sent to email@example.com
- website.com routes the mail to the host at NEW
- NEW then uses the new MX record to rout it to the servers at OLD
- Hey presto, the email should appear in the email inbox at firstname.lastname@example.org at OLD.
But this isn't happening. I get a 550 error telling me to turn on SMTP authentication, which I've read is a sure sign that I've got the MX configuration wrong. Any assistance on this would be really greatly appreciated.
tl;dr: Friend wants to move site hosting to NEW, but keep email hosting at OLD - I don't know what to do with MX and nameservers and so on to make this happen.
