Line breaks at 72 chars in Mail.app

Question

Hi,
Since 10.6.2 (Mail.app v4.2), Mail.app has been useless if you need to conform to standards on certain mailing-lists, since it doesn't break lines at 72 characters.
The solution has been to downgrade Mail.app to v4.1 (the one coming with 10.6.1) manually after each new Snow Leopard-release.
I'm not aware of what changes was made between v4.1 and v4.2 to break it like this, but it involves not sending 'format=flowed' (amongst other things) anymore.
This change has to some degree been discussed here; https://discussions.apple.com/thread/3040166
After upgrading to Lion, there is no way to downgrade Mail.app to v4.1 like before.
Does anyone have _any_ suggestions to a way to achieve line breaks at 72 chars using Mail.app in Lion?

I have the same problem. It also happens in notes.
Now I created a note in Mail on my Macbook and had this problem: Backspacing a line moved it above the previous paragraph. Then I opened the same note on my Ipad, and I did not have the problem, I could simply backspace the same line and it was connected to the end of the previous paragraph. What I did see in my Ipad note however was that the two paragraphs had a different font (which was not visible on macbook, until I edited it on my Ipad). Somehow my macbook mail creates unsolicited separate paragraphs, which use different invisble fonts, and these paragraphs may not be merged.
The same problem probably also causes email messages that I compose on my macbook to end up at the recipient in a very different font (i.e., lines/ paragraphs are larger and/or in different font.) than what I see when composing the message. This is really annoying, because it makes you look like a complete moron who is unable to compose a properly edited message.
