I assume you're talking about the internal line-based (not full-screen) message editor?
I tried this myself just now (using ZMODEM) and it worked as expected:
E-mail: F
Sending E-mail to Digital Man #1
Subject: test
Enter message now (9999 lines max). Type /? on a new line for menu. ----+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+-- RE: Feedback
/upload
[X] XMODEM-Original (SEXYZ) [1] XMODEM-1K/CRC (SEXYZ)
[Y] YMODEM-1K (SEXYZ) [G] YMODEM-G (SEXYZ)
[2] YMODEM (SZ) [Z] ZMODEM-windowed (SEXYZ)
[9] ZMODEM-streaming (SEXYZ) [S] ZMODEM-segmented (SEXYZ)
[L] Local Copy
Protocol or Quit: Z
Start transfer now (Ctrl-X to abort):
**B01
45 lines (1,008 bytes) received.
and I can then /l (list) the message and /s to save.
