[Solved] Error: no immediate delivery: more than 10 messages received in one connection

If you are receiving below error message in the exim log

"Error: no immediate delivery: more than 10 messages received in one connection"

then you will have to edit the exim configuration file and make some changes.

1) Login to the server via shell as a root user

2) Edit the exim configuration file using any favorite editor

vi /etc/exim.conf

3) Search for "smtp_accept_queue_per_connection" , if not preset then add the line

smtp_accept_queue_per_connection=30

4) Save the exim configuration file and restart exim service.

5) Deliver all the mails in the mail queue forcefully.
