Dear postfix users

we have been having the following issues with our postfix the past few weeks.
- delayed mails
- rejected mails via spamhaus due to XBL blacklisting of customers ip address

These issues never happened before.

Could it be due to too many active internet connections? Why are there so
man foreign address connected? Is it possible to kill these processes if
they are taking up resources?

Here is a snapshot of some of the connections on our server
