Exchange 2010 limitations

Hi,

I am just trying to figure out what the amount of CC's you can put on one email is before Exchange 2010 considers it spam, and where you can change that if you wanted (I am sure its not recommended).  

Also, Time Warner Cable puts a limit on it as well, does anyone know that limit?  If Time Warner Cable kicks it back, will the error message come from the exchange server?

Please help!

I dont think there is a limit to CC's ..... there is a limit to number of recipients and that can be checked on the Connectors.

If there is a limit on the Exchange server ..... yes it is going to send a Undeliverable.

Most ISP policies revolve around the number of outgoing emails per hour. They vary by ISP but 50 is probably an average, per sender. Having your own Exchange server probably bypasses the outgoing limits, however, so you would have to worry about spam filters on the other end and places like http://www.spamhaus.org who monitor that kind of issue. If you are going to be doing a lot of this kind of emailing, perhaps consider using a service that is designed for it, such as Constant Contact.

Outlook 2010 has a limit of about 29k for a list size, so the number of contacts varies greatly depending on how much contact info is stored about each contact. I'm pretty sure that the system will reject anything over 5,000 addresses at once, but you will probably run into other issues external to your system long before that number.

There are also external hosting sites that allow large numbers of email to be sent and are designed for volume email. See http://www.kvchosting.com/bulk-email-hosting.html for an example.

No matter what method you are using, make sure you have permission to send, because very little will get by the spam controls for very long if ir really is spam, and you will risk blacklisting your IP or domain.

Restrict the Number of Recipients per Message
http://technet.microsoft.com/en-us/library/bb310760.aspx

You can restrict the number of recipients per message at the following levels in your Exchange organization:

    Mailbox
    Organization
    Connector (for Receive connectors only)
    Transport server

Are you trying to send all users external ?
Ideally they have to whitelist your email address or domain as many emails surely from one ID can be considered as SPAM.

Also there has been some suggestions given by Experts so please respond rather ignore to get your issue properly resolved.
