[fetchmail]Receive auth errors

Hi all,

 

At the moment auth errors on staff mailboxs which are being forwared from
pop3 email to their exchange account are returned to the user, how do I have
those auth errors emailed to myself so I can fix the auth problem on their
pop3 mailbox?  Is this what set postmaster does? Does that user go to the
linux mailbox ?

 

Thanks

 

Cheers,

Jon
