Wow, good piece of info Bill, thanks! If I knew for sure that I would be continuing with Imail, I would probably implement Declude very soon. I may do it anyway if Scott is confident that Declude can be adapted to work with whatever other email server we may decide to migrate to.
NIX is not even out of the question at this time. At least with that we could cut many of our ongoing costs significantly and maybe continue in this market. With Microsoft changing all the time and the cost of keeping their OS up to date, and now this, I am having some serious concerns about our whole business structure as it is today. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Landry Sent: Monday, November 01, 2004 4:11 PM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] A Quick Note from the Ipswitch Executive Team ----- Original Message ----- From: "x" <[EMAIL PROTECTED]> > >> It's also possible that spammers will also create a new SPF of their own > >> until they are caught them create another.

However, if you are not blocking outright via SPF, and are instead using it as part of a weighting system like Declude JunkMail and SpamAssassin do, then you can reduce the effect of false positive SPF forwarding failures by using the trustedforwarder DNSWL & RHSWL at http://www.trusted-forwarder.org in either Declude JunkMail or SpamAssassin. Since most here use Declude JunkMail, here are the rule entries to support these two trustedforwarder whitelists: TRUSTEDFORWARDER-DYNA ip4r wl.trusted-forwarder.org 127.0.0.2 -5 0 TRUSTEDFORWARDER-RHSBL rhsbl wl.trusted-forwarder.org 127.0.0.2 -5 0 If someone here is using SpamAssassin and would like the trustedforwarder rulesets for SA, let me know.
