Re: [mlmmj] Problems with microsoft

Hi,

Have you tried looking up your mlmmj server's IP address in the various 
blocklists. The following will do a lookup and that might help you to 
see if it is just Microsoft or whether others think your server is a 
problem.

That will at least give you an idea as to why the blocking may be happening.

Regards

Richard
