    In WHM under "Tweak Settings > Mail", I can see this tip:
    I'm puzzled... Isn't it the opposite :confused:

    I think nowadays we get so much spam from spammers that use real email addresses as sender, that using the "fail" method is crazy/unresponsible. My email address is often forged by spammers and I get numerous bounces because of recipients that send an error message when the email can't be delivered. These mailer-daemon messages drive me crazy. I have nothing to do with these viagra and mortgage messages :mad:

    Worse for these servers that bounce emails when the message isn't deliverable: people who receive these bounces click the "Report as Spam" button of their webmail/email client, and at one point the server is blacklisted.

    Counldn't the "fail" method be just banned or at least put in bold red that it's not recommended?

    Actually, fail is preferred over blackhole in most cases. The main difference as far as a system admin would be concerned is server load. When you use blackhole on a server that gets a lot of spam and mail traffic, all unrouted mail is processed through the server before being discarded. When fail, the mail just bounces.

    You raise a good point about blackhole and the fact that you don't want the bounces getting to the users, which is a reason why some admins prefer that over fail. Both settings are useful for different setups, it's just a matter of preference.

    If your users are having a problem with spoofing, you may want to set up an SPF record so the mail is more likely to be silently discarded by a receiving mail system instead of getting bounced back to you. Changing the default address doesn't stop the spoofed emails from being sent out, it just keeps you from getting them thrown back.
