Trouble piping output of command to input of SENDMAIL

[evensenm]

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

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.

out of curiosity, does it work with @CLIP: ?

 

[samintz]

I did my own test and @CLIP: works. But @CON: does not.

 

[vefatica]

I wouldn't expect piping to sendmail to work.

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

command > clip: & sendmail recipient subject @clip:

 

[samintz]

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 [email protected] Party @c:\messages\invitation.txt

sendmail [email protected] Party @clip:

type myfile.txt | sendmail [email protected] Party @con:

 

[vefatica]

type myfile.txt | sendmail [email protected] Party @con:

Scott, I can't get that one to work. The server accepts the email but it doesn't contain the text from the file.

When I do it with a 60514-byte file, the server receives 166 bytes.

Does it, perhaps, contain the first letter of the text from the file?

 

[vefatica]

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:

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

type v:\w32tm.log | sendmail [email protected] test @con:

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

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

As @evensenm pointed out, the pipe is completely ignored. @con: expects you to type something and finish it with Ctrl+Z Enter.

Ok, thanks. I will surely keep that thing in my mind. I am glad I found your post where I found a lot of information. I also found the Free Essays on Cyber Crimes, Examples, Topics, Outlines - WritingUniverse website link where I found free essay examples on cyber crime traffic topics and many more.

Ok, thanks :)
