Anne, These look like normal log messages for postfix. The first shows the message being delivered to the mailbox. The rest is the log of the mail session. One shows the connected client. Another is cleanup and the last is qmgr purging the mail message from it's buffer as it was delivered successfully. If there were errors, the messages would be quite different. Errors with words like "reject" and "denied" are what to look out for.
