Possibly because you used the "flowed text" format defined in Internet
standard RFC 3676. To avoid this, either turn it off generally in your
Pine settings ("quell flowed text") or toggle sending flowed on a
message per message basis using Ctrl-V after the Ctrl-X to send a
message.

I'm sure that was the problem.
Thank you very much.
