Removal of valid IP addresses from the ERS database is needed when you experience any of the following:
- IP addresses appear in the Hosted Email Security console as blocked
- Emails and attachments are being rejected or bounced
To remove the valid IP addresses, select the ERS database that you want to remove it from.
The instructions for IP removal are also found in the Email Reputation Services site.
This database contains IP addresses proven to be sources of spam. IP addresses may be a multi-hop (multiple IP) open relay, a spam source, or a spam support service (e.g. a web server or name server).
To request the removal of the IP address from this database, the administrator who is responsible for the listed IP or IP block should contact the ISP provider and give the following:
- The bounce email received, or any other proof
- The rejected IP address
The ISP will then contact our investigators via email at firstname.lastname@example.org.
For more information on RBL+, refer to the Email Reputation Services site.
This contains IP addresses or an IP block from ISPs for their dial-up users who have been spam sources.
To remove an IP from the database, users should do any of the following:
The IP addresses in this database are open relays. They are not the real sources of spam, but can be used to relay spam mails.
Do one of the following to remove an IP from this database:
- For administrators: Secure your proxies so they will not be open relays.
- For those whose mail servers are hosted by ISPs: Contact the ISP.
- For those who want to request a removal: Use the Lookup Tool to verify if your IP address is in the database, and then complete the removal request form. After you submit the form, we will retest and then remove your server from the list if it no longer relays third-party mail.
This contains IP addresses that are open proxies. These are similar to open relays, but they do not use the standard SMTP port 25.

- Reconfigure your mail server so it will not be an open proxy.
- Contact your ISP if they are hosting your mail server.
- Request for the removal of the IP address. To do this, use the Lookup Tool to verify if your IP address is in the database, and then complete the removal request form. After you submit the form, we will retest and then remove your server from the list if it no longer relays third-party mail.
The NML contains IP addresses that are sources of mailing lists, but do not inform the owners that their email addresses are included in the list.
If the mailing list already has a procedure that secures approval to add an email address, a listed IP can be removed from the database. Contact the MAPS NML team through email@example.com to request a removal.
When an IP address is caught as a spam source, it is added in real time to the QIL database, and may stay there from five (5) minutes to 12 hours. The duration depends on how frequent it has been added to the database.
You can request to remove the IP address via the removal request form.
