Blat Error Handling

We almost finished our tsk to automatically send result reports files (In either .txt or xlsx formats) to customers of our POS System in Thailand.
 I will post more details of our Solution later, but right now we have an issue with Error Handling in Blat.
 

 I demonstrate this here on a Batch file we want to use to send a specific result to a customer. Once working, we will replace the to email, Date and other Data with variable, but here is a basic example with some extra log commands for debug:
 

 rem @echo off
 REM New Customers Email
 REM V. 1.01
 

 SET LOGFILE=C:\POS\Debug\MailLog.txt
 

 for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
 set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
 set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"
 

 set "timestamp=%HH%:%Min%"
 set "datestamp=%YY%-%MM%-%DD%"
 

 ECHO ----- START ------%datestamp% %timestamp% >> %LOGFILE%
 ECHO Now sending Order info to Management >> %LOGFILE%
 

 "C:\POS\Blat\blat.exe" -body "Here are New Order Details from RESTAURANT" -attach "C:\POS\PrintFiles\*.xlsx" -tf "C:\POS\BlatConfig\sprecipients.txt" -subject "RESTURANT Food Orders from %datestamp%" -debug -log %LOGFILE% >> %LOGFILE%
 

 IF !ERRORLEVEL!==13 GOTO :ERROR13
 IF !ERRORLEVEL!==12 GOTO :ERROR12
 IF !ERRORLEVEL!==5 GOTO :ERROR5
 IF !ERRORLEVEL!==4 GOTO :ERROR4
 IF !ERRORLEVEL!==3 GOTO :ERROR3
 IF !ERRORLEVEL!==2 GOTO :ERROR2
 IF !ERRORLEVEL!==1 GOTO :ERROR1
 

    
 

 GOTO :SUCCESS
 

 :ERROR13
 ECHO ERROR: Error opening temporary file in temp directory >> "%LOGFILE%"
 GOTO :FINALISE
 

 :ERROR12
 ECHO ERROR: -server or -f options not specified and not found in registry >> "%LOGFILE%"
 GOTO :FINALISE
 

 :ERROR5
 ECHO ERROR: Error Reading File (message text) >> "%LOGFILE%"
 GOTO :FINALISE
 

 :ERROR4
 ECHO ERROR: File (message text) not of type FILE_TYPE_DISK >> "%LOGFILE%"
 GOTO :FINALISE
 

 :ERROR3
 ECHO ERROR: Error reading the file (message text) or attached file >> "%LOGFILE%"
 GOTO :FINALISE
 

 :ERROR2
 ECHO ERROR: File (message text) does not exist, the server actively denied our connection or the mail server doesn't like the sender name. >> "%LOGFILE%"
 GOTO :FINALISE
 

 :ERROR1
 ECHO ERROR: File name (message text) not given or Bad argument given, Unable to open SMTP socket, SMTP get line did not return 220, command unable to write to socket, Server does not like To: address or Mail server error accepting message data. >> "%LOGFILE%"
 

 GOTO :FINALISE
 

 :FINALISE
 ECHO Error! Error! Error! >>"%LOGFILE%"
 GOTO :EXIT
 

 :SUCCESS
 ECHO Success! Success! Success! >>"%LOGFILE%"
 ECHO Here we delete the sent Files >>"%LOGFILE%"
 DEL /F /Q C:\POS\PRINTFILES\*.xlsx" >>"%LOGFILE%"
 GOTO :EXIT
 

 :EXIT
 ECHO ----- END -------------------- >> "%LOGFILE%"
 ECHO.>> "%LOGFILE%"
 ECHO.>> "%LOGFILE%"
 
 ECHO.>> "%LOGFILE%"
 

 

 The batch successfully sends the email with the attachment.
 Error handling is also logged correctly (and files not deleted)in case of SMTP server Parameters miscnfigured (WE store the Parameters in Registry; previous issues are resolved)
 

 But in case of missing Internet connection we receive the following Log entry:
 

 

 ----- START ------17-11-26 10:04 
 Now sending Order info to Management 
 Blat v3.2.17 (build : Aug 10 2016 22:32:21)
 32-bit Windows, Full, Unicode
 

 Read 1 TO address from C:\Bartender\BlatConfig\sprecipients.txt
 Error: Connection to server was dropped.
 *** Error ***  SMTP server error
 Error: Not a socket.
 Error: Not a socket.
 Success! Success! Success! 
 Here we delete the sent Files 
 
 ----- END -------------------- 
 

 

 Seems we don't catch this specific Error! How can this be resolved?
