Is there a maximum number of email addresses that can be included in a cfmail message? Is this number the maximum in each of the to, cc, and bcc or a combined maximum?
I don't think there is a maximum, other than the maximum length of a string, which I couldn't find in a quick search. I suggest using the BCC attribute to send your messages to. Also, if you have a lot of email addresses, you may want to use a list service. It makes management easier, the most mail servers will handle delivery better.
