Request for Assistance: SPF, DKIM, and DMARC Verification - Lua Version Compatibility

get-help
1

I need to verify SPF, DKIM, and DMARC records before sending emails. I’m attempting to install the following commands:

  1. Run the command: yum install luarocks

  2. Run the command: luarocks install spf_lua

However, I encountered an error:

Error: No results matching the query were found for Lua 5.3.
To check if it is available for other Lua versions, use --check-lua-versions.

To resolve this issue, I received a suggestion to change the Lua version. I am considering switching to Lua version 5.1. Before proceeding, I want to confirm if changing the Lua version might cause any issues with our Kumomta configuration. Additionally, I expect to install Lua 5.1 to address the problem.

Lua 5.4 is probably the installed version and LuaRocks latest version needs Lua 5.3 (I believe). KumoMTA should work fine with Lua 5.3 but I don’t see the need to go all the way back to 5.1

It sounds like you are asking for a paid Professional Services engagement to provide these. If you can confirm, I can send you a quote.
