By "your domain" you mean the mailing list's domain, right? As far as envelope sender use is concerned, SourceHut does this, adds a "Sender:" header on top, but leaves other message headers and the bodies alone. Here is a recent example, headers trimmed for brevity and addresses obfuscated: Return-Path: <[email protected]> Authentication-Results: naja.horus-it.com (amavis); dkim=pass (2048-bit key) header.d=lists.sr.ht header.b="TXR56UgM"; dkim=pass (2048-bit key) header.d=nasilyan.com header.b="yVwwu/q+" Received: from mail-a.sr.ht (mail-a.sr.ht [46.23.81.152]) Authentication-Results: mail-a.sr.ht; dkim=pass header.d=nasilyan.com [email protected] DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=lists.sr.ht; [...] Received: from localhost (unknown [46.23.81.154]) List-Post: <mailto:~sircmpwn/[email protected]> List-ID: ~sircmpwn/sr.ht-discuss <~sircmpwn/sr.ht-discuss.lists.sr.ht> Sender: ~sircmpwn/sr.ht-discuss <~sircmpwn/[email protected]> Received: from mail-10625.protonmail.ch [...] DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=nasilyan.com; [...] Date: Mon, 12 Oct 2026 05:34:33 +0000 To: <[email protected]>, ~sircmpwn/[email protected] From: <[email protected]> Subject: Re: unlisted source repo visibility on unlisted projects Message-ID: <[email protected]> In-Reply-To: <[email protected]> References: <[email protected]> Feedback-ID: 144157602:user:proton X-Spam-Status: No, score=-1.162 required=6.31 tests=[DKIM_SIGNED=-0.01, DKIM_VALID=-0.3, DKIM_VALID_AU=-0.1, DMARC_PASS=-0.001, HEADER_FROM_DIFFERENT_DOMAINS=0.249, MAILING_LIST_MULTI=-1, SPF_HELO_NONE=0.001, SPF_PASS=-0.001] Messages from SourceHut pass SPF checks and DKIM checks for both the original "From:" domain (in this case d=nasilyan.com) and SourceHut's mailing list domain (d=lists.sr.ht) when checked on naja.horus-it.com, my personal MX. -Ralph _______________________________________________ mailop mailing list -- [email protected] To unsubscribe send an email to [email protected]
