To make mail sending more secure. Is it possible to create a device-specific SMTP one-time password for only one or client connection?

Postfix / Re: Spam Filtering by Subject Line

I don't think spammers cares about the Reject status, because most of the times it's bots. Same for the greylisting. Most of them won't try again after a 4.x.x response.

So, greylisting (a bit aggressive for my taste) + spamassassin + spamhaus/blacklist checks = The best spam protection without false positives.

You can't have 100% spam protection without false positives.

Hi,
does CWP have greylisting?
Is it possible to activate it?
I think that this should solve many of spam problems, I am currently facing.

Thx

You are going to need to manually install it.

Hi iraqiboy90,

When I add the desired settings to the postfix mail configuration. Will I have a problem with the CWP mail server structure?

When I add the following parameters to the current configuration settings, it gives an error in the logs. Is it possible for you to share your configuration structure?

/etc/postfix/main.cf

smtpd_recipient_restrictions =
    permit_mynetworks,
    reject_unauth_destination,
    check_policy_service unix:postgrey/socket,
    permit

Another "feature" installed by stealth.
Hunt around in Admin, you will find it.
IT SHOULD BE DISABLED BY DEFAULT

Your are right,

CWP Settings > Yum Manager > Installed Packages

goaccess.x86_64 > remove

I'm deleting Goaccess but it's being reinstalled
