Overview ¶
Package mailfrom defines the custom MAIL FROM subdomain convention shared by sender-identity provisioning (which configures it in SES and emits its DNS records) and the outbound sender (which uses it as the aligned Return-Path).
One source of truth so three things always agree: what e2a tells SES the MAIL FROM domain is, the MX/SPF records e2a asks the customer to publish, and the envelope sender the relay actually uses. When a domain is sending-verified the Return-Path becomes `bounces@bounce.<domain>` — aligned to the From org-domain — so SPF aligns and the "via e2a" / "mailed-by" label disappears.

Constants ¶
const Label = "bounce"
Label is the subdomain prefix for the custom MAIL FROM domain. A fixed convention for v1 (a per-deployment config knob is a trivial future addition — thread one string to NewSender + the SES provider).

Functions ¶
func Domain ¶
Domain returns the custom MAIL FROM domain for a sending domain, e.g. Domain("acme.com") == "bounce.acme.com".
func EnvelopeSender ¶
EnvelopeSender returns the SMTP MAIL FROM (Return-Path) address used for a verified domain's outbound mail, e.g. "bounces@bounce.acme.com". The local part is arbitrary for SES (bounces route via the subdomain's MX to SES's feedback handler); `bounces` is conventional and human-legible.
