* feat: add configurable SMTP HELO hostname Allow the SMTP HELO/EHLO hostname to be configured separately from the SMTP server hostname. This is useful when the SMTP server requires clients to identify themselves with a fully qualified hostname different from the server address. * chore: remove vendored dependency changes * Bump go-pkgz/notify to v1.4.0 and document SMTP_HELO_HOST The HELOHost field lands in go-pkgz/notify v1.4.0, so the branch needs the bump to compile; v1.3.0 in master has no such field. The example module is tidied alongside, as any change to backend/go.mod requires. Documents the parameter in the parameters table and, separately, in the email setup page: what it does, that leaving it unset keeps the previous `localhost` greeting, and the case it exists for, a relay refusing the greeting under Postfix `reject_non_fqdn_helo_hostname`. Also records the current limit: verification emails for email authentication go through go-pkgz/auth's own sender, which has no equivalent setting, so the greeting there is unchanged. * Bump go-pkgz/auth to v2.2.0 and apply SMTP_HELO_HOST to verification email The verification email sender had no way to set the greeting, so a relay that refuses the HELO would accept notifications and still reject sign-in emails. EmailParams gains HELOHost in go-pkgz/auth v2.2.0, so the same SMTP_HELO_HOST now drives both paths. The example module is tidied alongside, as any change to backend/go.mod requires. --------- Co-authored-by: oli <someone@somewhere.tld> Co-authored-by: Dmitry Verkhoturov <paskal.07@gmail.com>
