Question about errors in exim_mainlog

I am new to troubleshooting email problems in the exam_mainlog. How come when there is a failure it starts with 5 nearly identical entries, each separated by a few seconds of time, followed by the actual error where the failed email address is identified? So all of the following is shown in the log to tell me that a particular email did not get delivered? Thank you!

Hello, Your server is clearly black listed at the Yahoo's end that's why you are receiving these errors. The important part is the specific error code, such as "BL21" or "TS01". These along with the link will tell you the specific SMTP error that Yahoo! is returning. Always check this list of Yahoo"s SMTP Error Codes so you know exactly why you are listed. Yahoo!

Hello, You could search 1bPzKw-0003s1-G4 in /var/log/exim_mainlog with a command such as:
exigrep 1bPzKw-0003s1-G4 /var/log/exim_mainlog
Check to see if that particular message is sending to multiple Yahoo email addresses. Thank you.

Thanks guys, but neither of you really answered my question, so I will politely ask again: "How come when there is a failure it starts with 5 nearly identical entries, each separated by a few seconds of time, followed by the actual error where the failed email address is identified?" Thank you.
