Asking this here
https://together.jolla.com/question/50527/ability-to-reorder-e-mail-accounts-list-in-e-mail-app/
asked/requested in 2014.
Still not solved nor answered.
So let me ask here once more:
does someone know where to tinker/squeeze the system to do a manual sorting of mail accounts?
(nota bene: not asking Jollla to implement this, just let me know where I can do it!)
