These are two different messages, one to a gmail account and one to a hotmail account. We have scripts that basically parse this data to map the message-ids: 6738886.1185961118923.SendAlerts.tomcatweb10 and 7035988.1185963106924.SendAlerts.tomcatweb10 to their "to" addresses and status: BBBBBBBgmail.com/Sent and BBBBBBBhotmail.com/Sent. It's a little more sophisticated then that, but it uses the SMTP ID to build the hash that associates these individual lines into detailed information about each email transaction that comes from our application.
