Composer: Add list of addresses/domains accepting HTML messages
as originally discussed on the mailing list: https://mail.gnome.org/archives/evolution-list/2022-March/msg00000.html
When the option "Prompt on sending HTML mail to contacts that do not want them" is enabled, any message sent as HTML will prompt the user to confirm that the recipient wants to receive HTML messages.
Can a feature be added such that a user can specify a list of addresses or domains that do, in fact, expect to receive HTML messages? To phrase it another way, it would be beneficial if users could whitelist addresses or domains in order to bypass this check.
