When a review is created Crucible sends e-mail notifications for all recipients.
In the "from" field of notification, e-mail Crucible uses e-mail from recipients profile but sends it via single SMTP server which doesn't connected with e-mail domain.
The income mail traffic filter service sees that e-mail comes from a mail server with another domain rejects such e-mail.
So we don't see any notifications regarding the review.
Is it possible to configure Crucible to fills "from" field some in an abstract non-personalized way like "no-reply@something"?
