I configured the Exchange 5.5 SMTP virtual server properties > delivery
for both Outbound and Local and both delay notification and expiration
timeout to 2 hours. The idea is that we need to know in a relatively short
time period if an email did not reach it's destination. We are still getting
many undeliverable messages 2 days after the initial send. Is there
something that I can do on my end to have the maximum delay be 2 hours or are
these emails being delayed externally? Thanks in advance!!!
