Trouble piping output of command to input of SENDMAIL

Is this WAD, or is this a bug? I'm having trouble piping the console output of a command/file to the console input of SENDMAIL

Code:
[100%] D:\Users\Mark\Documents\test 4\PipingTest>alias sendmail
*sendmail /ssl=2

[100%] D:\Users\Mark\Documents\test 4\PipingTest>sendmail "evensenm@outlook.com" "Test 1" This is test #1

[100%] D:\Users\Mark\Documents\test 4\PipingTest>echo This one worked as expected

[100%] D:\Users\Mark\Documents\test 4\PipingTest>type test.txt

Anytime I try to take @CON: as the text for SENDMAIL, it wants me to type from the keyboard at that point, rather than taking the text that's being piped to it.

I wouldn't expect piping to sendmail to work.

This sort of thing works. Maybe you could make an alias out of it.

Code:
command > clip: & sendmail recipient subject @clip:

The help contains this:
3. The message may either be entered on the command line, or it may be placed in a text file. To tell SENDMAIL to send the contents of a file as the message text, use @ sign, followed by the filename. You can use the same approach to send the text content of the clipboard (@CLIP:) or the console (@CON:):



sendmail abc@xyz.com Party @c:\messages\invitation.txt

sendmail abc@xyz.com Party @clip:

type myfile.txt | sendmail abc@xyz.com Party @con:

Does it, perhaps, contain the first letter of the text from the file?
I wondered that, thinking that SENDMAIL would execute after it received the first newline, but apparently not so. In my test below I sent a 60K file:

Code:
d:\mercury\queue> head /n 3 v:\w32tm.log
2019-06-25 Tue 02:50:19 ntp0.cornell.edu  Correction: +0.046 s  RTT:  25 ms
2019-06-25 Tue 03:18:27 ntp0.cornell.edu  Correction: +0.018 s  RTT:  33 ms
2019-06-25 Tue 16:55:30 ntp0.cornell.edu  Correction: +0.067 s  RTT:  20 ms

I issued

Code:
type v:\w32tm.log | sendmail vefatica@blah.com test @con:

and the message the server was prepared to deliver looked like this.

Code:
Received: from spooler by vefatica.net (Mercury/32 v4.80.149); 5 Dec 2022 16:40:38 -0500
