> After initial synchronization, clients send a PING request. The PING  
> request is a long lived request that remains active until either (1)  
> the heartbeat interval times out or (2) a change (such as a new or  
> changed email arriving on the IMAP server) was detected on the Horde  
> server.

> In the (1) case, the server issues a new PING request and waits  
> again. Assuming no changes or user-initiated SYNC requests (such as  
> manually refreshing the client) you would see only a single PING  
> request in the access log every n minutes, where n is the heartbeat  
> interval. This can be anywhere between 1 minute or 59 minutes.
>
> In the (2) case, the PING request completes by the server sending a  
> response that indicates there are changes, the client requests a  
> SYNC (which actually asks for, and transmits any changes), and when  
> that completes, it issues a new PING.
>
> In other words, for every new email (really for any type of change  
> to any object type), a SYNC is issued, followed by a PING. Put even  
> simpler, the more active the account is, the more PING requests you  
> will see in the log.
>
> Note: Some clients use a special type of SYNC called a hanging sync  
> instead of a PING - in these cases, the SYNC command doubles as a  
> PING command so you won't see any PING commands at all.

> Hope this clears things up...

Yes, thank you very much.
