If anyone sends email to a domain on our server, the email gets delivered succesfully. However, the original sender gets a message that says the email could not be delivered. Here is an example: This message was created automatically by mail delivery software (Exim). A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: firstname.lastname@example.org The following text was generated during the delivery attempt: ------ email@example.com------ opendir(/usr/bin//..): Permission denied at /usr/lib/perl5/5.6.1/FindBin.pm line 162 opendir(/usr/bin//..): Permission denied at /usr/lib/perl5/5.6.1/FindBin.pm line 163 Any ideas what this is? I checked the perms on the /usr/bin and there\'s nothing odd about them. Thanks!
