I have a dedicated server where I host a few small websites.
Just lately I have been having some emails blocked. I investigated by going to www.mxtoolbox.com
and see there that the server is on a blacklist at sorbs-spam
If I go to http://www.sorbs.net/lookup.shtml
the connections seem to take ages.
I thought it might be as well to register. I went to https://www.sorbs.net/scgi-bin/login
and get an error message

We recommend that you close this webpage and do not continue to this website.

I am wondering if there is any way I can find out why I am blacklisted and what I can do to correct the situation.
