Having a metronet address I was one of the first to be migrated, on 2nd October. It went fairly smoothly, just a couple of fairly minor glitches which were sorted out in a few days (usually after some back-and-forth with the Greenby bot. The ongoing problem is with the spam filters. With Plusnet I had virtually no spam, and AFAIK never lost a genuine email to spam. Now large amounts of spam getting through the filters (16 in the last week), and 1 or 2 genuine emails a day going to the spam folder on Roundcube. At one stage my reporting of the spam to report@phishing.gov.uk was being bounced back to me by Greenby as itself spam: this latter seems to have been stopped. I almost always have to enter my credentials twice in order to log in to Greenby, but that's a minor irritation.
