The parameters for the mailer daemon software that controls these
actions are set by the system administrators at each provider or
network. Some mail servers are set to wait longer for a response
from the receiving mail server, while other sending servers wait less
time for a response.
What you encountered is a service, operamail.com, that apparently has
it's mail server set to only wait for the proper protocol response
for a very brief time and then the software is set to bounce the
message if it does not get an expected answer from the recipient's
server.
I have the same situation with the mailer daemon from the host where
I have my ashlists.org located. It does not wait long for an answer.
If the recipient's site is busy or has a brief time out, then that
message I or my majordomo is sending is going to bounce.
Other mailer daemon software settings, such as your own ISP, may be
set more generous. It might wait a second or two longer for a
response and often only a second more wait can make the difference.
Your own ISP's mailer daemon may also be set to defer messages that
encounter busy signals or time outs and might store the message and
try to send it again later on an automatic time table. That too is
often a decision of the system administrator.
So to summarize, this is just an individual software setting decision
on the part of the system administrators all around the Internet.
