It seems that a couple of the mail servers are ‘black-listed’ by Mircrosoft/MSN/WindowsLive.
I attempted to jump through some of their hoops, but it’s evidently and IP based block, and not a domain based block…
Usually these just go away, but the latest one (mail5.m****here.biz) has lasted for about three days now.
Ironically, as I type this, it appears to be working again!
However, I’d still like to know - and maybe others would too - what’s the best way to handle something like this? Is there a standard period of time to wait before submitting a ticket? Can you do anything, or are tickets just a waste of your time?
A couple of weeks ago mail6 was getting blocked by Charter/Comcast - they gave me pretty much the same story: ‘sorry, somebody from that address is flooding our users with Spam…I know it’s not you…but too bad…’. Once again, the problem disappeared the following day, but it also popped back up a couple of times.
they don’t base it on spam as much as on volume, if someone sends a 100% legit newsletter they may still block it. they never send us reports unless it is really spam.
and if it is really spam, it is fixed by termination/removal of email access to spammer.
If we get continued bounce emails for more than a day, should we notify you?
They seem to block based on the IP of the originating mail server, not based on a domain name.
One specific example is my own domain, which is on mail5. From Saturday until Tuesday emails I sent to friends on MSN and Hotmail were rejected.
Ironically, I looked through all the black lists I could find, and none of them listed the Mail5 IP address, I guess Microsoft just maintains their own list…
