CC in email filters

[override]

Hi,
I was able to make cc work, but it doesn't work when espo users are sending emails. If email exists in espo filter doesn't work.
Anything to check?

Thanks

Hi,
Is it possible to customize email filters? I want to put mails in specific folder when CC field is matching criteria.
Tried something with espocrm/application/Espo/Resources/metadata/entityDefs/EmailFilter.json and espocrm/application/Espo/Resources/layouts/EmailFilter/detail.json but it seems it's not enough?

Thanks
