No. The linux kernel will (smartly) use any/most available memory to cache disk i/o, so all linux systems tend to show very little available memory. This is normal (and a good thing). FWIW, the free and top commands show memory usage, and this cached i/o shows up as 'cached', which hopefully will be a decent sized chunk.

Hi All,

My QmailToaster Server has 1.5GB memory and I've noticed that the available 
memory is always between 20-30MB. Do you think its a memory issue?

We have also noticed the same thing happening on our qmailtoaster server. Some 
mail comes through with a delay varying from minutes to a few days.

I usually use the squirrelmail webmail to view the mail and it shows the 
message was delayed because it gives the time the message was really sent, but 
puts it in the order of when it was received. For example, I receive a message 
from yesterday but it shows up today (with yesterday's day and time) in the 
middle of other current emails from today (I normally have my emails sorted by 
date with the most recent emails at the top).

I understand from the comment below that we can re-order/re-sort the mail by 
clicking on the date in squirrelmail. But my real question is how can I 
troubleshoot to determine what is delaying receipt of the mail and how can I 
correct it?

This mail is NOT from new senders, so it is not the delay of Spamdyke.

The same sender's mail is not always delayed. The amount of the delay for 
various emails can vary for the same sender as well.

Thanks in advance for any help in troubleshooting this.

     Hi all,
               Which Email client are using, if you are using squirrel mail 
then click on date button, you will get the mails in order.
