OJS 3: email protocol for sent mails?

Hello all,

OJS 3:
If I send an e-mail to a contributor using the ojs backend, I take it that the sending is not showing up in any log by default? Clicking on the “Editorial History” of the article reveals that review requests were sent and reviews submitted, but not mails aside these formal steps …

Any possibility to enable e-mail-logging?

thanks, CW
