Hi

I want to turn off wrapping when I compose email so that my
lines are as long as I need. But Thunderbird wraps at about 75
characters no matter what. I have tried:

Edit > Preferences > General >

Wrap plain text messages at 500 characters

but this doesn't change anything. I have sent emails
to various accounts, and wrapping always occurrs.
I have even tried:

Edit > Preferences > Advanced > Config Editor

and set:

mailnews.display.disable_format_flowed_support true
mailnews.send_plaintext_flowed false
mail.wrap_long_lines
false
mailnews.wraplength 500

Any ideas? Thanks.
