One of our servers is currently listed by Spamcop. Due to this listing you may find that some emails were returned to you citing the Spamcop listing. Emails will only be returned by systems utilizing Spamcop as a blacklist, which Spamcop itself warns against doing, as it will likely block many legitimate emails.
We have changed our server to send messages through a different IP so no further emails will be blocked. We apologise for any inconvenience caused by the listing. Although it is impossible for a Spamcop listing to correctly reflect an active spammer using FastMail.FM (because our automated systems immediately lock out spammers), problems with the Spamcop listing algorithm nonetheless cause FastMail.FM to be listed from time to time.
If you were impacted by these problems in Spamcop’s algorithms, please consider contacting the person you were sending to through some other means, and ask them to send the following to their ISP:
Dear email administrator,
I recently had an important email blocked from reaching me. This email was blocked because you use the “Spamcop Blocklist”. The email came from a server that does not have any active spammers.
Spamcop say about their blocklist (at http://spamcop.net/bl) :
This blocking list is somewhat experimental and should not be used in a production environment where legitimate email must be delivered… SpamCop is agressive and often errs on the side of blocking mail – users should be warned and given information about how their mail is filtered. Ideally they should have a choice of filtering options.
Is your service not a production environment where legitimate email must be delivered? Why have you not warned me and given information about how my mail is filtered? Do I have any filtering options, as Spamcop suggests?
Can you please either remove the Spamcop blocklist so that in the future important email to me is delivered, or give me the ability to opt out of this system?
