feedback. <br class="">
I verified the suggested points , its working as
require. Please find below inline reply for each. <br
class="">
<br class="">
I found that when big group email is getting
deliver ( i.e more than 500 - 4K members ) at that
time other emails are not getting deliver
simultaneously to user's mailbox. <br class="">
I verified this from live maillog i.e by doing
grep key words like "to mailbox:" / "Delivered:"
etc ...<br class="">
<br class="">
My mail queue issue is getting critical in peak
hours !! Kindly suggest. <br class="">

Verify that single instance store is working. If
