When the MOA are working, sometimes, the delete things they do not have to.
Talking about the incoming fax, in case you clic delete by mistake, it's impossible to find out which was the fax sent to trash. The reason is actually, the fax are ordered by RECEIVED date, and not deletion date.
Put a new column - deletion date - would be the solution to quickly recover from an error.
It happens a lot of times during a week.
