Hi all,
Seems like we're hitting the dreaded S3150 block list again having
introduced a new server our mail pool.
I've already logged two tickets with MS support about this, and
bizarrely email from us towards one of our Office 365 customers is fine
(but others aren't!), and we can't send anything to hotmail/outlook/live
at all. We're trying to get the addresses delisted and we're not
getting very far.
I'm also finding it impossible to add my entire AS, or even the entire
/22 my company has to SNDS. It always declares that "no such host is
known" or "Sorry whois.ripe.net will not let us do any more lookups
today". I then have to re-add all the IPs I just removed.
Having attempted this at various times of day, I am coming to the
conclusion that, actually, you can't add an AS to SNDS at all, and
adding a range of IPs requires rDNS for every IP in the block. That's
not the case in my network, because some of the blocks have extra IPs
that are not in use.
As I know we have at least one Microsoft person here, I appreciate that
you, personally, may not be able to do much about either of these.
However, my general frustration is at seemingly not being able to
communicate with anyone about this issue at all any more is a much
bigger issue than the underlying fault. It's costing my business
clients who are leaving because they can't deliver mail to Microsoft for
what (to them) is no obvious reason. I appreciate you want to fight
spam, and I understand the fine lines you tread. But, getting no
response to a ticket from last week, filing a new one last night,
getting no response to that with in the "expect response within"
timeframe, etc, is getting tedious.
If anyone has any hints how to add an AS or a netblock to SNDS, that
would be fantastic.
Regards,
Chris Malton
