sendAs, SendOnBehalfOf access and DL for a specific user

Hi-

Would you happen to have a script that will report the DL and the type of access (SendAs, SendOnBehalfOf) for a specific user?

I tried get-distributiongroup with the managedBy command, but that isn't exactly what I want, as this user may not always manage the group, but has rights to sendAs etc.

Any help would be appreciated.

Thanks!
