How SFTP configuration like MaximumReconnentAttempts, maximumRedeliveries and reconnectDelay works in Fuse ?

Issue

• User is having OnException block in camel route in which maximumRedeliveries and redeliveryDelay is used to reconnect with target SFTP.
• But in advance details section of target SFTP in switchyard, noticed two more properties related with reconnecting.

MaximumReconnentAttempts 3
reconnectDelay 1000 ms

• User has specified maximumRedeliveries as 10. so now code will try to connect with SFTP 10 into 3 equals 30 times. Is the understanding correct ?
• If yes, can MaximumReconnentAttempts and reconnectDelay be set to 0 ? As redelivery is being attempted by OnException block.
