Is it possible to specify IP addresses/ranges for which SPF checking is disabled?

Is there a way to view the event log file in real-time so that, say, it could be viewed by more than one user or PC simultaneously? Something similar to the Unix 'tail -f' command.

Hi

I use mTail for viewing log files in real time. It's free and works very well!

I've tried that one and it crashes SpamFilter.

Sawmill ( http://www.flowerfire.com - www.flowerfire.com ) is a log analysis tool that supports SpamFilter logs.

Please note that SpamFilter will continuosly append data to the logfiles. In general, any application that attempts place a file lock on SpamFilter's logfile will likely cuase a problem, even though SpamFilter "should" still be able to function (without being able to log) properly. Please note the "should". For reliable operations, SpamFilter will require that no other applications place file locks on the current logfile.

Thanks for the reply.

And what about a sort of SPF whitelist for certain IP addresses?? Is this possible?

No, that is not possible. Please note that the purpose of SPF is to ensure that email received from a domain has been sent by an IP that has been authorized by the domain to send emails on their behalf.

If a company decides to implement SPF for their domain, that *usually * means that they do not want anyone to send emails using their domain as a "from" unless it is sent by one of their server.

..note the "usually". We understand that there may be exceptions, as there are exceptions to all filter. The only way around that is to use one of Spam Filter's whitelists, even though they are "global", and not specific for a particular filter.
