Hi All,
ICloud started deferring a lot of Groups.io email this afternoon, so I
contacted their postmaster address. They responded promptly. I am just a
simple unfrozen caveman lawyer, and I'm not sure I understand what's going
on. I'm hoping someone might be able to help (Groups.io is an email

Hi All,
As we continue to warm up some new mail servers, we're getting rate limited
on one of them, with the following error:
451 4.7.650 The mail server [45.79.224.9] has been temporarily rate limited
due to IP reputation. For e-mail delivery information, see

I run an email groups hosting service. For many years now, each group

One of groups.io's servers was listed by Spamhaus starting Saturday
afternoon (https://www.spamhaus.org/sbl/query/SBL638016). I've been trying
to contact them ever since, but they've been silent. I am humbly asking for

Hi All,
fyi, over the next week or two, we'll be warming up 6 additional mail
servers, to complement the two that we already use. Below are all 8 IP
addresses; the first two are our original servers.

We're getting this response when sending to att.com from 66.175.222.12 and

addresses on their site, and we are not being blocked. So maybe it's a rate
