In which case those mail systems are not in compliance with the RFCs.=20 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.
