Restrict how many emails can be send at a time by Email job RSCONN01

Hello All,

Is it possible to restrict how many number of emails can be sent out from SAP by the email send job? My requirement is - if there are 20000 emails sitting in the send queue, can the dispatcher send out 2000/3000 emails only every time RSCONN01 job runs (currently this job runs every 10 mins). So when the first time job runs, 2000 emails are sent out. After 10 mins when the job runs again, next 2000 emails are sent out.

I looked at the variants for RSCONN01, and there is no field which provides this restriction.

Any help?

Thanks,

Fahad
