I have a mail program in my delphi project to send a newsletter to
clients. I use the Indy SMTP and message components to send my email.
There are over 300 recipients and I get a #4.5.3 Too Many Recipients Error.
Normaly there is no limit to the number of recipients. So this should be a temporary error.
Is there a way to handle this ?
Or maybe there is a limit and therefore I have to split up
the recipients programmatically and send multiple messages with timed intervals ?
