The SMART_HOST macro allows you to specify the host that should relay all outgoing mail that you are unable to deliver directly, and the mail transport protocol to use to talk to it.

Make sure sendmail was install in your server, if not install first:

Open your configuration file:# vi /etc/mail/sendmail.mcAppend or modify macro that read as follows :define(`SMART_HOST',`smtp.net4india.com')Replace smtp.net4india.com with your actual smtp server address. If line contains word, dnl remove the dnl word. Regenerate a new sendmail.cf config file with m4 command:# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cfRestart sendmail service:# /etc/init.d/sendmail restart

   # rehash
2. Go to the file path and run this command:
   # bzip2 -d  filename.bz2

   # bzip2 -dk  filename.bz2
   
   
   A useful option for bzip2 is the -c switch which causes bzip2 to write the uncompressed output to stdout which can easily be redirected to another option. For instance, to search the compressed file file.bz2 for the string tech-recipes, use:
   bzip2 -dc file2.bz2 | grep tech-recipes

2. Delete the temp content inside this folder
3. Try upload file to system
4. Upload function should be ok by now.

Good luck!
