Question

Email

Hello.
Are there solutions to monitor incoming and outgoing mail from mailboxes?

Answer 1

Yes, any, in principle, if they are in the local office network.
But the same Yandex mail for a domain also allows you to do this in some cases.

Answer 2

Make your own mailer and read its logs

Answer 3

Their.
They allow you to do whatever you want.
Back in far, far 2004, I wrote a sendmail filter that worked as an anti-spam and at the same time had the "shadow copy" functionality, when a copy of each letter was added to a separate folder.
