  1. One thing to note is that the email was voluntarily blocked by the recipient's server. The people receiving the email setup SpamCop's block list on their server. SpamCop didn't directly block the email from O365. If SpamCop were to remove the entry from the block list, the recipient would then add their own that bypasses the Spamcop block list.
  2. @Brendon, could this be what you might be talking about?

  3. One possible alternate to the SpamCop blocking list could be SpamAssassin. You can tie weights to SpamCop such that it would take more than one Blocking list to block spam. You can also whitelist email addresses or make rules that override the SpamCop blocking list. if certain keywords show up in that email.
  4. Are you using a shared IP?

    https://www.spamcop.net/w3m?action=checkblock&ip=40.107.94.90

    Looking at the blocking list entry, it looks like someone maybe reporting emails as spam to SpamCop.

    Some things to note, you might want to check that your email list is using double opt-in or else anyone can add an email address. You might also need to check routers and cameras have not been hacked.
  5. You know you are irritating a spammer if they are trying to retaliate. The only real way to make a spammer think your account is dead is to reject the email at the border server. You might be able to accomplish this by "blocking" the user and sending it to the spam folder, but most of the spammers will just try a different address to get past your filters.

    Since Gmail and Microsoft don't let me control the border server, I setup my own email server and use SpamAssassin to filter out the spammers. A few fine tuned rules and it blocks the spammer. In watching the rejections, I noticed that some spammers retry more often when it rejects.
  6. You do have to click each link in the mail for every spam. I believe SpamCop did this so that you would double check that the message is actually spam (because we don't want to accidentally report good messages).

    Now if the email address was never used for legitimate email, then I believe you might be able to work out using the quick.xxxx8888xxxx8888xxxx@spam.spamcop.net address. (I believe you might have to work with the deputies to have this turned on.)
  7. Wow, they finally got blocked. One thing to note is that Microsoft was warned numerous times before their inaction allowed the IP to show up on the blocklist. I have been getting abuse from their IP with a few messages a day from a .shop address trying to immitate some paypal links.
  8. fe80:: is the local interface address and is not to be used on the internet. It is used to dynamically acquire an actual IPv6 address.

    More likely that one of the server's IPv4 address is on the blacklist and resending the email went through a different outbound server. I have heard that a lot of people get spam from outlook.com/onMicrosoft.com. So I wouldn't be surprised if they had a server on the black list.

    Because of this kind of issues with the random blocks, I now lean toward using SpamAssassin instead of just a single blacklist. It takes a combination of various keywords and multiple blacklists in order for me to block inbound email in my server.
  9. So, I believe in the forums that there are two types of Microsoft spams. One is from the IPv6 issue where Microsoft is using millions of addresses internally, but I believe SpamCop mailhosts only remembers fifteen. The other, is where they are actually coming from microsoft as you have listed. I believe the *.onmicrosoft.com might be their cloud setup. For some reason, I seem to have very little spam the past week for some reason. The only suggestion I have (after you are attempted the reporting to them) is to report as many as you can to feed the blocking list.
  10. The SpamCop blocking list is not tied to emails, but it is based on the IP 54.240.27.58. I currrently do not see that entry in the block list, but it possibly could have been when they tried to send you the email. The receiving server should have an entry for "dnsbl/bl.spamcop.net" and would have sent a response with the following link.

    https://www.spamcop.net/w3m?action=checkblock&ip=54.240.27.58

    54.240.27.58 not listed in bl.spamcop.net
