Error message upon attempting to send email to many recipients

[Sandy M]

I keep trying to send out an email to about 20 or so recipients, and no
matter how carefully I check my email addresses, etc., I keep getting this
message "Task 'mail.comcast.net - Sending' reported error (0x80070057) :
'Could not complete the operation. One or more parameter values are not
valid.'". Is there any way to find out exactly what parameter is invalid?
I've checked all the semi-colons, spaces, email addresses, started over, etc.

Are all of the addresses resolved?

Call Comcast. They probably put on a limit on how many recipients you can send to.
It is a control for Spam. Either the 20 is too many at a single time or you have
sent out too many with multiple email addresses and you are over the allocated limit

Thanks, my sister works for them (lucky her) so maybe she will know. All the
email addresses were perfect, so it may well be some sort of limit.
Appreciate your input!
