I received from my mail host company the message:
'The message "'354 Enter message, ending with ." is common message
provided by the recipient mail server. It means the receiving system is giving a go ahead to begin sending the message. '
That was a few hours after I started sending the batch of 900. So I hit the "Resume" button. I immediately got back a message saying the mailing was complete. However, I did not see a link for the SMTP report I requested. Can I be confident that the newsletter did, indeed, go out to the remaining addresses after it stopped at 450?
