Bigfoot, the mail forwarding service that at one time promised "free email addresses for life", has recently moved at least some of their servers to Korea. One of my users has her bigfoot address forwarded to my mail server. Mail to her looks to our server as if it comes from bflitemail-kr2.bigfoot.com.
All well and good, except that the korean IP is in the blackholes.us cn-kr list. Since it's, you know, in Korea. That list is one of our best spam stoppers. Bigfoot, providing better customer service to my user than I expected, asked me to unblock them.
Questions: 1: Has anyone else run into this with Bigfoot and if so, how did you solve it?
I haven't run across this with Bigfoot specifically, but I have had one or
two users who regularly receive legitimate mail from blacklisted IP ranges.
If you know the IP address(es) for the Bigfoot server(s), you can put them
in your Client Hosts list, which will override the blacklisting. As long as
Bigfoot keeps their server(s) locked down reasonably well (I don't know
about that one way or the other, but I suspect that they probably do), that
should not significantly increase your spam exposure.
This scares me, as *any* message originating from their servers will be passed through your system, even to third parties.
How about making the user's email address a white hole in the router, since she will be the only one receiving from Bigfoot:
<[EMAIL PROTECTED]> = user
Of course, this would remove spam protection from that user, but I think it's a price she may have to pay for using Bigfoot, given their current approach. It just seems a safer approach from the admin perspective.
My two cents, Tim
