I have a MS Exchange 2003 smtp queue of undeliverable mails to a particular email domain (@bigpond.com).
I did a
smtpdiag firstname.lastname@example.org email@example.com /v
with results in attachment.
From what I could make out from the results, there does not seem to be any issue. Yet the queue stubbornly stays unmoved. Meanwhile outbound mails to other recipients continue as usual.
Administrative support of the receiving domain, @bigpond.com claim that they do not use any spam filters. In any case, if sender, @devon.co.nz is blacklisted, would'nt their mail server had rejected the connection?
Could an experts please help interpret the diagnostic results and suggest further trouble-shooting procedures?
Thank you very much for helping with reducing the stress!
