Emails not delivering

John_Hull — Wed, 08 Apr 2026 15:03:33 GMT

Over the last couple of months, I've occasionally been getting "undeliverable" responses to emails, in the format:

Your message did not reach some or all of the intended recipients.

Subject: RE: XXXXXXXX

Sent: 08/04/2026 15:59

The following recipient(s) cannot be reached:

'XXXXXXXX' on 08/04/2026 15:59

Server error: ’452 <xxxxxx@xxxxx> recipient rejected - too many recipient in last hour’

If I wait a while and resend it, it goes through fine. They've been to different recipients using. What's going on?

@John_Hull This error has been going on for months, possibly not all the time but it comes and goes. There is a very long thread about it ....

Nothing you can do to fix it. Plusnet have tried but it seems to come back again.

Thanks for the response. It doesn't happen too often, but it's quite irritating when it does.
