I don't think there is a native way to do this using NTBackup. You will need to build a shell script of some type around it and have the logfile emailed to you using a utility like Blat.

Here's a script using blat that I found that might meet your needs (use at your discretion with testing - I have not confirmed if this works or not):

 @echo off
 setlocal
 
     Rem *************************************************************************
     Rem Get date into variables so we can create good media name and BLAT message
     Rem *************************************************************************
 
 for /F "usebackq delims=" %%i IN (`date /t`) DO set dt="%%isbs"
 for /F "usebackq delims=" %%i IN (`date /t`) DO set sbj="Back Name %%i (Backup)"
 for /F "usebackq delims=" %%i IN (`date /t`) DO set msg="Backup description %%i"
 
     Rem ********************************
     Rem Perform backup to media pool LTO
     Rem ********************************
 
 rem C:\Windows\system32\ntbackup.exe backup "@C:\Backup\DailyFBU.bks" /d "Daily Backup" /v:no /m normal /j "Daily backup.job" /l:f /f "C:\DailyFBU.bks"
 
 
     Rem *******************************************
     Rem Set folder name containing backup log files
     Rem *******************************************
 
 set fld=C:\Documents and Settings\administrator\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data
 
     Rem **********************************************************************
     Rem This dir command will list all log files sorted by date in bare format
     Rem **********************************************************************
 
 set fcmd=dir "%fld%*.log" /OD /A-D /B
 
     Rem ***********************************************************
     Rem set command will set lastf variable to the last file in set
     Rem ***********************************************************
 
 for /F "tokens=* delims= " %%i in ('%fcmd%') do set lastf=%fld%%%i
 
     Rem ******************************************************
     Rem Delete prior Blat log file and prior lastbackuplog.txt
     Rem ******************************************************
 
 del C:\Backup\blat.log
 del C:\Backup\lastbackuplog.txt
 
     Rem ***************************************************************
     Rem Copy Unicode log file to single-byte-per-character text file
     Rem ***************************************************************
 
 type "%lastf%" > C\Backup\lastbackuplog.txt
 
     Rem *****************************************************************
     Rem Mail latest Backup log file to techsupport with embedded text version
     Rem *****************************************************************
 
 C:\Backup\blat.exe "%lastf%" -server mail.domain.com -f notifications@domain.com -subject %sbj% -to recipient@domain.com -body %msg% -sig C:\Backup\lastbackuplog.txt -attach "%lastf%" -mime -debug -log C:\Backup\blat.log -timestamp
