If this IP address is NOT a shared hosting IP address, this IP address is infected with/emitting spamware/spamtrojan traffic and needs to be fixed. Find and remove the virus/spamware problem then use the CBL delisting link below.
In some unusual cases, IP addresses used in shared hosting (especially those using IPSwitch Imail or some configurations of DMail or Surgemail) can trigger CBL listings. If this is a shared hosting IP address, make sure that your mail server software is set up to identify itself in its mail connections, not each of your customers.
WARNING: If you continually delist 92.90.21.5 without fixing the problem, the CBL will eventually stop allowing the delisting of 92.90.21.5.
