The Securence Block List, is a database of IP addresses that have sent a large quantity of spam to Securence.  Entries in this database are completely manual and are done after researching the IP address’s sending history.  In general, if an IP address has only ever sent spam and no clean messages, it will be listed.  However, there are other reasons an IP address may get listed.

Entires are generally not removed until requested.  To request removal, send an email to with the following information:

  • The IP address listed
  • Your contact information
  • The 550 response you received from our server

We will send you a confirmation email during the delisting process.  If your email address does not work, we will be unable to delist your IP address.  If your IP address is listed on Spamhaus or SpamCop, we will not remove the listing.  We generally honor all other delisting requests.
