1and1, one of the world's largest hosts, blocked my spamcop! in SpamCop Blocklist Help Posted May 23, 2007 In a technical field, it is very important to use the correct terminology or the correct things don't get fixed. In my experience with many different levels of expertise, most people these days, even my parents, understand that they need to check their "Held Mail", "spam Folder", "Junk Email", etc due to the actions of spammers. Perhaps you need a more sophisticated server software that does allow for individual targets. There are many available. You can also disable any blocklists that you do not agree with their rules for listing. As far as your "does not like" definition, it may be sufficient for a very low level discussion of the topic with someone. It is not sufficient when discussing an issue with delivery of email. "Spamcop has detected a large percentage of spam coming from that server and listed it" is generally more accurate. Yes, if you have a spamcop email account, then spamcop can divert a message from a listed server to the Held Mail folder. Other than that, spamcop can not physically interact with any email transmission. The receiving server asks spamcop if a specific address is listed. SpamCop answers with a yes or no. The receiving server then makes a decision as to what it wants to do with that message. It is up to senders of messages to ensure their servers are being maintained properly so their messages can be delivered. If your provider is not able to supply an account that is not affected by blocklists, it is up to you whether you want to keep supporting that provider. I have changed providers about 6 times in the last 15 years, most of the time changing because of the service I was being given.
