Problem when handling incoming email by script

[volcano]

Hi my problem is that my Solaris server will receive emails from another Lotus Notes mail server. It will send the emails to the .forward of an email account. The .forward will then call another UNIX script to process the emails. One day I found that if an email contains ".-" (exclude double quotes" characters t end of line and then a line break in the subject, when my script reads that line, the program seems to hang up and occupies almost all CPU. I tried to replace those characters when reading lines but in vain. The general code of the script is as follows:
-----------------------------------------
#!/bin/ksh

LOGS=/export/home/ewp01/maillog/`date +"%Y%m%d_%H%M%S_"`.log

while read -r `echo line|sed "s/\.\-/\.\-/g"`
do
line2=`echo $line | sed "s/\.\-/\.\-/g"`
print -r $line2 >> $LOGS
## business logic ##
done
## business logic ##
------------------------------------------
Do you encounter such strange problem?

Sorry, some typo errors... below is correct one

I don't understand what you're trying to do here:

[tt]while read -r `echo line|sed "s/\.\-/\.\-/g"`[/tt]

Shouldn't that just be:

[tt]while read -r line[/tt]

Maybe that was just a typo in your post?
