[NubeNinja]

Hi,

I've read this: https://spamauditor.org/best-practices/ ... from-self/

After I received this:

I know that its not a recommended practice to block self account but, is there any way to minimize the affectations due this?.

Please note: I have all my own IPs whitelisted as I received tons of false possitives marked as spam.

Thanks in advance

Hey NubeNinja,

Based on our understanding, you're receiving a lot of spam where the sender address has been forged using domains hosted on your own servers. Did we understand you correctly?

In that case. MagicSpam has the 'Local SMTP sender addresses must authenticate' Spam Policy which rejects messages from local senders when the SMTP transactions is not authenticated. Just make sure that the actual user who owns the email address has their email client set up to authenticate when sending to their own address.

Otherwise if you provide us with your IP addresses, we can review them further to find the reason they have been listed. You will probably want to contact us directly through our support email account (support@magicspam.com) for this to avoid exposing your IP addresses to the Internet.
