Hi, I've a problem with your antispam system.
When I try to send a mail to the domain "bolognafiere.it" it says that my ip is blacklisted, so I check on your site: https://www.sophos.com/en-us/threat-center/ip-lookup.aspx and it says my IP is ok.
Next I check my IP on mxtoolbox and it's ok again!
How can I remove this block?
Thank you
Matteo
