Should be related to snowshoe. But you need to stop mailing from affected IPs to drop the listing faster.

dear experts,

we are running Port25 for a while now, with no major issue. We have several blocks of IPs for a total of aroud 250 IPs - 1/2 used.

Today 60% of our IPs  are blocked by spamhaus, on very different set/range of IPs and really different category of traffic - from the nicest to less nice traffic.

IPs are blocked - then ubblocked after 1 hour then blocked again.

Any help would be welcome.

What's the best way to "warm" up to Yahoo? Here's what I have changed my config to after emailing back and forth with Port25 Support:

<pattern-list defaultPatterns>
   rcpt-to /@yahoo.com/ virtual-mta=yahooMta
</pattern-list>

<domain $yahoo>
    max-smtp-out 20
    max-msg-per-connection 4
    smtp-greeting-timeout  5m   #  added in v3.2r17
    mx-connection-attempts 10   # added in v3.2r16
    dk-sign yes
    dkim-identity strict-from
    smtp-pattern-list yahooBackoff
    backoff-to-normal-after 4h  #added in v3.5
    backoff-max-msg-rate 400/h # Use with PowerMTA 3.5
    backoff-retry-after 60m
    backoff-notify emailadmin@somedomain.com
</domain

The pattern list I added today to limit the amount of vMTAs from 16 to 2.

Should I include a 'max-msg-rate'?

There are very many things that go into your "email reputation" ... Senderscore is only 1 very small part of it (and not as widely used as it once was). The main free email providers (gmail, hotmail, aol, etc.) all use many, many metrics to figure you out... that includes:
IP address
IP neighbors
SMTP From
From Address
Reply-To Address
Other Email Headers
etc, etc, etc.

so when you move to a new geo and new IP addresses you need to start small and grow your send volume and establish a positive pattern. Many ISPs will only allow so many messages from a new / unseen IP address until they "prove themselves" as a good IP sender, etc.

Well,
have you heard about ip reputation and warm-up? :))))))

Hello CaLViN, I'm a bit new to this world so not entirely familiar with IP reputation. I do know that when I Google it, a top hit is www.senderscore.org where I've ran all 16 of my public IPs and so far they have all been above 90.

Yahoo expects you to wait 48 hours before requesting a follow up so I'm doing that today.

Make sure you start off sending to only clickers, openers and other engaged segments. Yahoo is throttling you because they don’t like what your sending and their users are complaining.

Thanks ReyM. We're still sending to the same clients. Our clients are teachers, school staff, students, and parents and non of that has changed since migrating to the new server.
