Has anyone here noticed a problem with vpopmail/qmail and the authorized open smtp feature? I've noticed that if the number of hosts in the 'relay' table is excessive then the smtp server takes an extremely long time to answer. The connnection is established, but you don't get a "220 <hostname> ESMTP" response for a very long time. I've narrowed this down to the fact that it appears the entire contents of the "relay" table in the vpopmail database appears to be loaded into memory each time a connection is established. Is there a reason this is done? Would it not make more sense to take the source ip address of the connection and somehow do a single comparison on the table instead of loading the entire contents into memory? If I sent this to the wrong list or I'm missing something glaringly obvious, please let me know. I am running clearopensmtp, but right now with over 1500 hosts in the table it is causing Outlook and my network monitoring software to time out connections. -Jeff
