Cisco Cisco Email Security Appliance C690 User Guide

 A case could exist in a newly installed appliance where the oldest message 
counter shows a message but, in fact, there are no recipients shown in counters. If 
the remote host is connecting and in the process of receiving a message very 
slowly (that is, it takes minutes to receive a message), you might see that the 
recipients received counter displays “

0

” but the oldest message counter displays 

“

1

.” This is because the oldest message counter displays messages in progress. 

The counter will be reset if the connection is eventually dropped. 

If you suspect delivery problems to a specific recipient host or you want to gather 
information on a Virtual Gateway address, the 

hoststatus

 command displays this 

information. The 

hoststatus

 command returns monitoring information about 

email operations relating to a specific recipient host. The command requires that 
you enter the domain of the host information to be returned. DNS information 
stored in the AsyncOS cache and the last error returned from the recipient host is 
also given. Data returned is cumulative since the last 

resetcounters

 command. 

The statistics returned are displayed in two categories: counters and gauges. For 
a description of each item, see
