Hi all,
 
This isn't a strict Sun issue but I'm basicly hitting the limit of my very
small Unix knowledge. Basicly I am running a solaris box with a content
filter on it. Now when the content filter picks up a "bad" e-mail, it moves
it to a quarantine directory on the system. I have a script that came with
the software that allows me to resend any messages that get block, but the
only bad thing is this script doesn't take into consideration multiple
e-mail recipients. I have tried modifying the script to now avail (the
looping doesn't work after I try it).
 
There are two files, a control file and a data file, that the software
generates each time it blocks an e-mail. The control file looks like this:
 
T<sender@somwhere.com>
F<reciever1@somewhere.com>
F<reciever2@somewhere.com>
F<reciever3@somewhere.com>
OSender Name
SThis is where the subject is
<<--Other Stuff -->>
 
The data file is a standard mail message file. Now the snippet I need to
modify on the resend code I think is this:
 
for i in AF*; do
  HEADER=$i
  DATA=DF`echo $HEADER|cut -c3-256`
  FROM=`head -1 $i|cut -f2 -d\<|cut -f1 -d\>`
  TO=`head -2 $i|tail -1|cut -f2 -d\<|cut -f1 -d\>`
  SUBJECT=`head -4 $i|tail -1|cut -c2-256`
 
I modified it to this:
 
for i in AF*; do
  HEADER=$i
  DATA=DF`echo $HEADER|cut -c3-256`
  FROM=`head -1 $i|cut -f2 -d\<|cut -f1 -d\>`
  MESSAGENUM=`grep -c $i`
  LINENUM=1
  CURLINE=`expr $LINENUM + 1`
  while [ $LINENUM -le MESSAGENUM ] do
    TO=`head -$CURLINE $i|tail -1|cut -f2 -d\<|cut -f1 -d\>`
    LINENUM=`expr $LINENUM + 1`
    CURLINE=`expr $LINENUM + 1`
  done
  CURLINE=`expr $CURLINE
  SUBJECT=`head -$CURLINE $i|tail -1|cut -c2-256`
 
And this screws the loop and the cut command. Any idea's why ?
 
And to also throw a spanner in the works, for some reason Outlook messages
will occasionally have the to line in the control file like this:
 
T<<email@address.com>>
 
So if you know a better way to solve both of those issues, other wise I
would be happy with just getting multiple recipients working.
 
Cheers
