Here's what the rep from Fastmail said initially, along with the spam headers.
Looking at the headers you provided for your test message, I do see that Microsoft is adding numerous spam flags to the messages:
X-Forefront-Antispam-Report:
CIP:66.111.4.25;IPV:NLI;CTRY:US;EFV:NLI;SFV:SPM;SFS 10001)(189003)(199004)(52294003)(106002)(5660300002)(52956003)(86362001)(58126008)(16003)(16586007)(42186006)(50466002)(558084003)(31696002)(221733001)(50226002)(51416003)(84556003)(6266002)(126002)(31686004)(476003)(48376002)(7116003)(22756006)(1096003)(6666004)(26005)(6676002)(3480700005)(6916009)(47776003)(8676002)(13146002)(336012)(356004)(9686003)(15650500001)(486006)(246002)(4270600006)(7596002)(305945005)(7636002)(2351001)(2361001)(79770400001);DIR:INB;SFP:;SCL:5;SRVR:MN2PR13MB3600;
I closed my Fastmail account tonight after being a very happy paid customer for a long long time. This really hurts. I added to the ticket that other folks here seemed to be having similar issues and that maybe FM should reach out. Don't know if they will.
Just wanted to say thanks to everyone here for the help, and take care. This is me signing off. Cheers. |
Yes, we can see that the message has a spam confidence level of 5 (suspected spam, but not high confidence spam) and that FastMail is not a trusted partner. However, we have limited visibility as to why the message is deemed spam. We basically have
SFV:SPM (The message was marked as spam by the content filter.)
Based on this, it is surprising that using your own mail system would make a difference. Presumably, it does not change the message content, unless the content filter is looking at the message headers and does not like something there.
