Right-click on a folder and chose "Check for New Mail" from the context 
menu. This will not only check for new e-mails in this folder once, but 
permanently.

Well, Horde/Imp uses IMAP IDLE features and those associated with it 
(e.g. QRESYNC) to be able to check if there are new messages available 
on the mail server.  For all I can tell, this works quite well when used 
in combination with the IMAP proxy software (originally developed by the 
squirrelmail project and pretty much unmaintained nowadays, unfortunately).

AFAIK, there is no feature to immediately alert an Imp user of an 
incoming message, i.e. there is always polling between the AJAX client 
in the browser and the Horde server.  I suppose it would be feasible to 
achieve immediate alerts by using a more modern approach like 
Websockets, but I'm not aware of any efforts to implement anything like 
this.  I think Horde's ActiveSync client does something along those 
lines already, i.e. permanently keep open a connection between the the 
client and the Horde server to be able to signal incoming messages as 
they appear.  But since I don't use ActiveSync, there's only so much I 
can tell about it anyways.
