Hi all, First time posting. Hoping someone with Charter/Spectrum-side visibility can take a look or point me to a working contact path.
My personal/family domain hendricks.nu (Google Workspace, in use ~10 years, low volume, a handful of personal emails per week) is being rejected by Charter/Spectrum at the sender level. Bounces look like: 550 5.1.0 <[email protected]> sender rejected. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information AUP#In-1010 This affects mail to charter.net, chartermi.net, and presumably the other Spectrum-managed domains. The block appears to be on the sender address or domain rather than the sending IP (a Google Workspace shared outbound). What I've checked and done: - Auth is clean: SPF pass (include:_spf.google.com), DKIM pass with a custom 2048-bit key d=hendricks.nu (I recently moved off the default *. gappssmtp.com signing in case that was a contributing factor), DMARC p=reject with full alignment. mail-tester.com scores 10/10. - [email protected] now returns 550 5.1.1 recipient rejected. The mailbox appears to have been decommissioned, presumably as part of the late-2024 email platform conversion. - I sent a delisting request to [email protected] a day or two ago (from Gmail, with full bounce details, auth status, and remediation summary). No bounce, no response yet. - Re-tested sending from [email protected] to a non-existent charter.net address. Still getting AUP#In-1010, confirming the sender-level block is still active. The affected use case is genuinely personal. My dad sends to a handful of Charter-subscriber recipients (family and friends) and his mail is being silently dropped on their end. Not a bulk sender, not a marketing list, nothing on any public RBL that I can find. Is there a currently-working contact path for sender delisting at Charter/Spectrum that I'm missing? Or if anyone Charter-side is reading and willing to take a quick look at hendricks.nu, I'd very much appreciate it. Thanks, Kyle Hendricks [email protected]
