How can I manage queue? or incoming traffic?

[Justin Kim [Permanent Link]]

Hello,

 

I am noticing some problems on my postfix server.

So far it was fine but now I get active+incoming+maildrop queue is flooded by 3000 messages and plus then my server is not coping well.  I have amavisd running too but I didn't have any problem until today for about 6 months.

Does anyone can give me a hand to manage that queues? or incoming traffic?

 

Thank you in advance,

 

Justin
