I believe there is some limit that is being exceeded (Timeout=100000). Do we know if these emails are being sent asynchronously?
Customer is trying to email a large volume of smtp email messages, we get an error, but in smaller groups of emails around 100-125 they are processed without error. Would you know what would be causing this?
