In which case those mail systems are not in compliance with the RFCs.
RFC 2821 Section 4.5.4.1 says:
Retries continue until the message is transmitted or the sender gives
up; the give-up time generally needs to be at least 4-5 days. The
parameters to the retry algorithm MUST be configurable.
ie. 4-5 days is the /minimum/ time to hold messages in the queue and
keep retrying.
Cheers,
Matthew
