I run a subscriber only email list with maybe 1400 subscribers (facebook has drastically diminished the number of
subscribers and use). Things were going along swimmingly until recently microsoft started blocking our list to their
email users. At first I was getting bounces with this message:
"...has been temporarily rate limited due to IP reputation"
Then, today I am getting this:
"SMTP error from remote mail server after pipelined MAIL
FROM:<[email protected]>"
which I assume means they have blacklisted our IP address.
The type of posts to this email list is limited to trade and community announcements only, so nothing that constitutes
spam. We only get about 4 or 5 messages a day average on the list.
So I've been scrolling around on Microsoft's help/troubleshooting pages and am flummoxed. Any advice? The list is hosted
on a VPS I believe by Hawkhost.
On https://sendersupport.olc.protection.outlook.com/snds/JMRP, I see the below (not sure how this paste will translate
on an ascii email) which lists some IP addresses that are not ours. Ours is similar (on the 198.252..) but not the
..110. subnet. Not sure how smart it is to post IP addresses.
That's about all I have now. Hoping for advice.
