Ok. So, it is normal that some MTA (like exchange server) didn't handle correctly line which are larger than this 1000 bytes limit.

I upgrade to 1.5.90 (with many problem). In fact I take an old Mandrake system (9.2) and used red-carpet to update to evolution 1.5.9 from the evolution-snapshot-devel channel.

Since I can't migrate my account (evolution crash on migrating my Contact) and because 1.5.90 is to unstable, I setup a new account and make my test with a fresh message. It was the same. Mail arrived corrupted and from ethereal line are not folded when they were sent to SMTP server.

I also perform another test on a Mandrake 9.1, but this time with the ximian package instead of Mandrake one, in case of. Again, same behavior, same corrupted mail, same capture with ethereal.

I could reproduce the same behavior on a fresh installation with my personal account instead of my office account.

If I remember right, this problem didn't occur with evolution 1.2.x series. But this was too old and take to many time to test.

Thanks for your help.
