Hi Matti ,
We have tried make option too.
Even then its the same , recipient address rejected .
:(
sendmailcf package also is installed.
Anything to be done at Mail server end ?
They are saying you just have to configure smtp with authentication , we have given our login credentials, even after configuring the same , its still ecipient address rejected . ( whitelisting done for that server too from where we are sending mails )
