Hello there, a longtime Thunderbird user here. I am currently evaluating either I can switch from Thunderbird to eM Client 1:1. I have figured out most of the features. I thing left is a feature introduced in this addon in thunderbird: https://addons.thunderbird.net/en-US/thunderbird/addon/flexible-identity/
Its called flexible identity. It allows to create a rule that triggers when one wants to send a message. For example, if you have 4 different account and one of them is you work email, like firstname.lastname@example.org, you always want to use it when sending messages to people in work.com domain. In case you try to do it from a different account, the addon would ask you either you want to apply the rule after you press send. And the rule could be, to always use email@example.com when sending to work.com domain addresses. This way it is impossible (or at least very hard) to send a message to someone from an incorrect account.
Is such functionality available in eM Client? I would appreciate all help.
