Big D, In regards to your advice, There is the possiblity that a connection timed out on a connect out to another mail server, in which case you would have the sender as <> but the message could still potentially be deliverable. Am I understanding you correctly on this? Therefore I want to explicity only dump messages that have been rejected by another mail server with a 5xx error codes. These are items that have been migrated to the slowest queue, because they have been undeliverable for 24+ hours. So here is an example of what I have in my queue. Munged to protect the non existent recipients. Diagnostic-Code SMTP; 554 5.7.1 Sender address rejected by MX servers for domain Diagnostic-Code SMTP; 550 5.1.1 <icsu0081_cs.montana.edu>...
