IMail.FetchLimit parameter for IMAP4 transport protocol

Hello,

I am trying to limit the number of unread emails to be fetched by the IMAP server for every polling interval.

For this requirement, I have tried adding additional parameter IMail.FetchLimit =1 and also added the FetchLimit parameter value 1 under module configurations for XIMailAdapterBean.

However, the sender mail channel always picks all of the unread email instead of picking 1 at a time.

Please advise.

I have gone through following links but didn't find solution to the problem.
