As stated this might have been an interesting article when it was complete.
However: apart from the missing images I read no arguments in his article to come to the conclusion that a script task is simpler to send mail from SSIS than the Send Mail task. To me the conclusion is therefore no more then an opinion.
To come to that conclusion I would like to see the stated (more complex) functionality, with an implementation both using a script task and using the sendmail task. Only then it could be pointed out what the simpler and more flexible way is to do so.
That might also stimulate a discussion about the used techniques, in which optimizations and best practices might be developed/shared.
