There's a merged pull request on the void-packages repository

opensmtpd-filter-rspamd: update to 0.1.8
https://github.com/void-linux/void-packages/pull/46426

Description:
- I tested the changes in this PR: **NO**
- I built this PR locally for my native architecture, (amd64-musl)

This brings in a rather important IMHO security fix: it's possible to crash filter-rspamd by attempting to log in as a user with a "|" character in it.  Doing so will also quit opensmtpd since it dies once a filter exits.

Furthermore, this update will also be needed for the next opensmtpd version since it'll bump the protocol version.

I haven't actually run this on void linux, but I'm using it on other systems and the [diff is quite small](https://github.com/poolpOrg/filter-rspamd/compare/v0.1.7...v0.1.8), I don't expect actual breakages.

(edit: I've mailed the maintainer since I don't know their github account)
