Darwin cgi engine and sendmail

[Sivakatirswami]

Here you go Dave.. .from the application here that generates our  
Daily Hindu Press international..

This is running from a rev desktop stack in the GUI, but I'm pretty  
sure it will work from a CGI...

One  caveat there is a conf variable set for security, which limits  
the length of a single line input to sendmail to 990 chars. (google  
"sendmail 990" for this obscure bit of info)  Longer strings are auto  
broken with CRLF as far as I can tell. There are all kinds of scary  
admonitions not to change this setting (old mail client issues) hence  
my dreaful work around in the switch statement below.

Of course this assume the email is properly formatted I haven't  
included that here.. if you need it I can post that too... in the  
following "tMsg" contains a properly formatted, multi-part html/plain  
text email...



     # fix endlines to unix a
     replace numTochar(13) with numTochar (10) in tMsg

     # temp back up to hard drive
  put ($HOME &"/Desktop/temp.txt") into tPath
     put tMsg into url ("binfile:" & tPath)

     # introduce line breaks at the end of sentences into lines  
longer that 990 chars
     # and two such breaks in the case of lines longer than 1980 chars.
     # will break lines up to 2970 chars.
# Lines longer than that (very unlikely) will be broken by Sendmail  
at 990 with CRLF
# which appears as a space in the html email and a line break and  
space in the plain
# text version. This eliminates both:
     repeat for each line tLine in tMsg
         switch
         case len(tLine)<990
             put tLine & cr after tWrappedMsg
             next repeat
             break
         Case len(tLine)>1980
             set the itemdel to "."
             put round(the number of items of tLine/3) into tBreakPoint
             put cr before item (tBreakPoint+1) of tLine
             put cr before item (tBreakPoint*2) of tLine
             put tLine & cr after tWrappedMsg
             next repeat
             break
         Case len(tLine)>990
             set the itemdel to "."
             put round(the number of items of tLine/2) into tBreakPoint
             put cr before item (tBreakPoint+1) of tLine
             put tLine & cr after tWrappedMsg
             next repeat
             break
         end switch
     end repeat

     set the itemdel to "," # just in case!

     put tWrappedMsg into tMsg
     replace cr with "\n" in tMsg #probably not needed if everything  
is running from CGI...
     put tMsg into  $DailyHPIEmail

     # Do shell stuff and send mail, very simple...

     set the shellcommand to "/bin/sh"
     put "echo -e $DailyHPIEmail | sendmail -f hpi.list at hindu.org " &  
(fld "to" of cd "staticText")  into tCmd

     # check on status and inform user
     put shell(tCmd)  into tResult
     if tResult is empty then
         answer "Mail was sent...." with "OK"
     else
         answer tResult with "OK"
     end if

end createFinalEmailAndSendIt
