[AccessD] what is the total number of e-mails which can be sent at once

Hi

I am using sendobject to send emails out of Access
It goes through and creates a BCC list of email addresses to send to from a
table... does anyone know what the maximum number of addresses Outlook will
send to a one time as I thought I read somewhere that MicroSoft put in a
limit to stop spamming... I would like to know the 'magic number'

thanks

Phil
