Emails to Yahoo from my server tagged with X-YahooFilteredBulk?

Hiya,



I host a small mail server and I've noticed that emails FROM my server TO Yahoo accounts are tagged with X-YahooFilteredBulk: [IP address]. I only have a couple of customers using this server and I know that they are not spamming.



1. I would like to remove my server's IPs from the spammers list. How can I do that? I tested by adding my test account to my Yahoo address book but that didn't change it. I read other answers here that say ';change your server's IP address';. That's a drastic change and not easy to implement because I don't control the MX records for my customers.



2. Also, I would like to understand how my server got on the list in the first place, so I can make sure my users follow the rules in the future to prevent it from happening again.



3. If there IS an IP address in the X-YahooFilteredBulk, does it only go to the Bulk folder if SpamGuard is on? My test messages don't go to my Bulk folder.



Thank you!Emails to Yahoo from my server tagged with X-YahooFilteredBulk?
Changing your IP address won't help for very long -- and it'll look like you're a spammer with something to hide. Yahoo! has a bunch of help pages about this:

As for question #3, I bet you marked the message as ';not spam'; at some point. Yahoo! will respect that preference for your account, even if the mail is still seen as spam for everyone else.
