acarlsson Posted February 7 Share Posted February 7 What in my setup have I done wrong when I get extremely many Undelivered Mail Returned to Sender, such as the below? I understand why they arrive, but I don't want them. And I have tried to write a mail rule that delete them asap, but they tend to end up in the spam folder instead. And I want to keep my spam folder clean, meaning I spend a lot of time to delete these… Any suggestions? Oh my heavens! how much I hate spammers!!!

opentype Posted February 7 Share Posted February 7 This particular mail is the result of activating the Post before Register feature. It will cause more spam registrations. Link to comment Share on other sites More sharing options...

Safety1st Posted February 8 Share Posted February 8 (edited) Do you have properly configured MX & PTR DNS records? Why is your mail server not capable to drop emails? Edited February 8 by Safety1st Link to comment Share on other sites More sharing options...

Why is your mail server not capable to drop emails? Everything is set up to work as a normal email server, and works as it should. I don't understand what you mean by "drop emails"? The mail that I get (as shown above) is the mail server saying there is no mail account on that address, because the spammer have used an email that doesn't exist. Thus I (as in the admin of the site) am sent an email every time these emails won't reach their destination. So basically I wonder if there's a way to turn off the "Did you forget to submit your content?" email, or a better solution to this behavior?

opentype Posted February 10 Share Posted February 10 You can turn off “Post before Registering”. Type “post before register” in the ACP search to find it. Afterwards, guests need to register first before submitting a post. acarlsson 1 Link to comment Share on other sites More sharing options...
