System.Net.Mail.SmtpClient and limits on the number of BCC addresses

[Claire]

Hi
I'm using BCC to send mass emails to members of a club.

System.Net.Mail.MailMessage Message =
new System.Net.Mail.MailMessage(Sender, Recipient, Subject, Body);
for(int cnt = 0; cnt < BCCList.Count;cnt++)
Message.Bcc.Add(new MailAddress(BCCList[cnt]));

Is there a recommended limit to the max number of BCC entries I can add to a
mail message?
I notice in my IIS SMTP server that max values can be set for certain
things.

thank you

Hi,

Try and error my friend

Also post this question in the IIS group. (or the exchange) Remember that
IIS use a smart host to deliver the emails.
