I use a tiny ISP and have only once or twice had the "Hotmail doesn't like your address" thing.

Given that Spamcop catches around 300 spams a day to my various addresses, many of those with "Hotmail" as the (possibly forged) origin, it does seem that pots are maligning kettles.

I usually phone the person concerned, tell them Hotmail is rejecting their mail, and ask them if they have a "proper" e-mail address. Most do. Problem solved.

Maybe I'm old fashioned (yes, I know) but I prefer to download my mail, excluding the stuff held by Spamcop, and read it on the PC. I glance down the Spamcop list - there's about one false positive a month among the 10,000 or so spams - and then "delete all". But I get to see all the stuff, in case.

I had a Hotmail address but soon gave up using it. Ditto Yahoo - BTYahoo seems to share Hotmail's trigger-happiness.

Keef:

It's not just BTYahoo which shares Hotmail's trigger happiness. I had a paid for yahoo email account ($20 US/yr.). Too many false positives, to lengthy time in email reception by others, etc.

I canceled the paid for account and now have the free one. With all the annoying adverts that go with that.

I now use Apple's email service via me.com and have had absolutely no problems with that, so far.

Posts #3 and #19?

NB Not my 'ISP' but my 'shared' domain host. It IS hotmail and their hallucinogenic spam filter that is causing the problem. No other email system.

There you go:

1)-3) correct. Now add 4) All domains now sending to hotmail with no issues.

Both hosting company and ISP are aware of problems with Hotmail which seem to stem from the switch to Windows Live Hotmail.
