Limit the number of external recipients by type (TO, CC, BCC)

Is there any way to create a policy/rule to limit the number of external recipients by type, e.g.:
- max. 10 recipients in the TO: field
- max. 50 recipients in the CC: field
- max. 5 recipients in the BCC: field

Also commercial tools would be an option.

Not using Exchange

Client level code is probably the only way.

Client-side coding is _not_ an option (because many different eMail clients for Windows, Linux and Mac are used).

Well you certainly can't do this using Exchange natively and I'm not aware of any tools to do it using third party hardware. Think the answer here may be no if client coding is a no go.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Why third-party hardware?
I read something about event sinks or maybe also hub-transport rules?
But I am not a software developper, so I am looking for either a commercial tool or some code samples.

I meant software, sorry, I'm getting tired.

If you have Exchange 2007 transport rules may be an option but would require coding using shell commands as there is nothing natively built into the Exchange wizards for determining number of 'types of recipients' . I'll see if I can find something tomorrow for distinguishing the total number of cc, bcc using code, or someone on the forums may have done this before if it is possible,

The answer here is no, it cannot be done natively using Exchange.

I think http:#30140898 is a valid answer to this question.

It can't be done without some extensive bespoke coding.
