Re: Cisco Ironport and Senderbase...how to get delisted?

In sort, wait...  Once you're de-listed from SpamCop (which is owned by
IronPort and plays a non-trivial part in their SenderBase scoring) you
should find that your reputation increases fairly quickly - normally within
24 hours presuming that the spam has actually stopped.

I am in the process of cleaning this up.  Spamcop and others were good
about
delisting us promptly.  Others will within the next day.

However, "Senderbase", apparently used in Cisco's Ironport, will let you
look up
your IP and tell you that your reputation is "poor", but offers no way to
get
delisted.  It refers you to Spamcop, which I imagine they rely on for
listings,
but not delistings.

For now, I'm re--routing per domain to a second server, but I'd appreciate
any
tips if there are any.  Seems a lot of .edu's use senderbase.
