The mailing list for listmasters using Sympa

[Steve Fisher <address@concealed>]

Hi,

I am running on Centos 7 with Postfix and MySQL with configuration for a single domain. I have configured opendkim so now all my mail is going out with DKIM headers being added by postfix and that is working fine.

Now I see in https://sympa-community.github.io/manual/customize/dkim-arc.html that I should get  Mail::DKIM and configure that as well. My outgoing messages are being signed by postfix already. What is the added benefit of doing it in Sympa and do I need to stop postfix doing it as well?
