long time to deliver...

[Daniel Abad]

Hi!!

Anyone could help me? 
I have vpopmail and qmail working together, and few days ago, its taking
long time to deliver the messages... 

All my virtual users, sometimes they receive the messages and sometimes
don�t. At the outlook, a message appears saying that the pop3.server.com.br
is unreacheable... but I can stil ping it.

Do you have any idea what should be?? 
Nothing appears at /var/log/maillog

Tks all.
