Sending Error with Exchange 2010

[OAgency]

Hi All,

I'm using MaxBulk Mailer v 3.4 on a old 1.33Ghz Mac (not Intel).

When I try and send using an Exchange server to any addresses outside its own domaine, I get the error: Unable To Relay

Internal emails it delivers without a problem.

Could anyone point me in the right direction? Is this a MaxBulk problem, or is it a setup on the Exchange side?


Thanks,
OA

This is an authentication problem. Set the MaxBulk Mailer authentication to ESMTP and enter your account id and password. It should then work properly.
