Re: [Declude.JunkMail] IPFILE vs REMOTEIP
One difference I know of, is that if you use a HOPHIGH parameter, IPFILE will search more hops. Tehrefore with a HOPHIGH and IPFILE anemail with forged headers could trip the test. REMOTEIP only uses the last hop. - Original Message - From: Goran Jovanovic To: Declude.JunkMail@declude.com Sent: Monday, January 30, 2006 9:35 AM Subject: [Declude.JunkMail] IPFILE vs REMOTEIP Hi, Is there any performance benefit of using an IPFILE lookup vs a REMOTEIP lookup?

RE: [Declude.JunkMail] IPFILE vs REMOTEIP
That sounds like IPFILE will use more resources since it is going to test up to HOPHIGH whereas REMOTEIP will have to be invoked in a filter file but it is a single test.

Re: [Declude.JunkMail] IPFILE vs REMOTEIP
As Scott pointed out, IPFILE will work on the same number of hops that Declude is configured for, so it is possible that you could be scanning multiple hops. IPFILE also does not support SKIPIFWEIGHT or other tweaks to end processing of a filter. In other words, it always runs. A custom filter with REMOTEIP can be skipped and REMOTEIP is definitely limited to the last hop's IP address. It also supports CIDR ranges like IPFILE does. In the end however, you should find that this particular type of check, regardless of the mechanism, is very fast and it would take a lot to overburden your system.
