Why is it necessary to have the boilerplate text in every email?

Question

This one:
>This message was sent to: p taz
>To post a reply to the thread message, either reply to this email (recommended) or visit the message page: http://forums.adobe.com/message
>/1906449#1906449
>If you post by replying to this email, be sure to leave the square-bracketed text at the end of the subject line as it is. This will help ensure that >your message is posted correctly.
Firstly, it just highlights the dodgy-looking thing with the subject line, and secondly, I usually automatically flag any post with my name in it in case I need to respond to someone but now EVERY email that comes in gets flagged and I cannot (automatically) differentiate between high and low priority emails.
Really, guys, was there a point to that or did the page just look too empty!  Of course I know who you posted it to, I am reading it!!!!!!

Answer 1

If at the first place I am getting all the methods synchronized by calling
Collection c = Collections.synchronizedCollection(myCollection);
that means no two threads can enter the data structure of this collection, I am not getting how ConcurrentModificationException will be thrown while iterating thru this collection?
Can u please explain in a little depth?
