2023-04-29 📌 A rather concerning HostingUK three day gap in email service

Tags 🏷 All 🏷 Tech 🏷 Personal

It's been about fourteen years since I had anything like a service outage with a web host, and that was with PlugSocket... who were subsequently bought out by UnitedHosting (2012) who in turn were bought out by Iomart / EasySpace / HostingUK (2018). And they've been very good on the whole, helping to sort out an SSL cert and getting things upgraded to a modern rather than grandfathered hosting package a few years ago.

Then at the end of the day on 24th April / 25th someone mentioned they'd tried to send me an email and it failed, and I realised I hadn't had any emails since the 21st. Which is very unusual, but things had been busy and I hadn't noticed. Sending from the account worked, but test emails from a work account got errors like this:

Reporting-MTA: dns;
Final-recipient: RFC822; [mailbox]@[personal domain]
Action: failed
Status: 5.0.0
Remote-MTA: dns;
X-Supplementary-Info: < #5.0.0 smtp; 550 is not allowed to send mail from [work domain]. Please see the SPF record, with scope mfrom, identity [work email address], and ip>

See if you can suss out what's going wrong there.

It tallies with the general answer from support. Looking at domains on it's potentially more than a few other customers affected. And a service that for most individuals is of higher importance than a site being available having not been for roughly 72 hours, and not identified and resolved until raised by a customer because it was technically responding but misconfigured.
