Hello all, Running Win2K SP3 with Exchange 5.5. I just looked at the Outbound Queues for our Internet Mail Service (IMC) in exchange 5.5. There are over 600 e-mails in queue to be sent and over 590 of them say that they are originating from '<>' . What does this '<>' mean? All originating e-mail should be from 'any_user@xxxxxxxxxxxx' <mailto:'any_user@xxxxxxxxxxxx'> . I have relaying locked down to only pc's on my domain. Where are these coming from. Thanks for any info.
