Could not connect to smtp host:< ip >,port : 25,response :421

Hi ,

I am running single threaded java program to sends emails out.It sends approx 250 emails per minute.
Emails are sent out successfully but after some hours I always get messaging exception "Could not connect to smtp host:< ip >,port : 25,response :421"

Once this comes it never stopped coming.I had to restart app server to get if of it.

I am wondering why emails are sent out even if messaging exception occurs?

any help will be appreciated.

Thanks,

Legend
