I'm sending an email blast to a recordset loop with 278 records in it. I had a progress bar setup but when I sent the blast, it didn't work correctly and started sending our duplicates. So, I removed the progress bar completely and now the email blast sends to all of addresses but ends in the following error:
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /mailinglist/send3.php.
Reason: Error reading from remote server
Has anyone run across this before?
