Hello Misit,
According to Microsoft documentation, they do indeed use that header. Here is what I was able to dig up on this end. " https://docs.microsoft.com/en-us/exchange/antispam-and-antimalware/antispam-protection/antispam-stamps?view=exchserver-2019 " -Keith |

Hello Everyone,
Just a quick question, I have noticed the header field Outlook.com adds to there header, doesn't seems to be there anymore. "X-MS-Exchange-Organization-SCL" Does anyone noticed this ? if so, what other options they use to mark a SPAM email? Thanks In Advance Misit |

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. |
