Thank you. The DKIM signature 'd=lists.gambas-basic.org' is added by 
Hostsharing when our mailinglist sends the mail. Multiple DKIM 
signatures are allowed:

I am unsure how to change "simple" to "relaxed", but I don't see this as 
a problem because we have no problems except with Protonmail and we 
don't change any content AFAIK.
