dspan824,

As mentioned in the support email, the issue is likely caused by this bug that is fixed in the licensed version of SpamFilter but that has not been added to the eval version yet: 

// New to VersionNumber = '4.7.4.250';

{TODO -cFix : Outbound TLS connections were only being made with TLS 1.0, even if TLS 1.1 and TLS 1.2 were configured and in use correctly for inbound emails}

{TODO -cFix : Due to a regression error since v4.5, the AUTH LOGIN appeared in the welcome banner even if authentication was disabled in SpamFilter

We provided a workaround earlier today, but please feel free to contact again either via our support email or via the forum if you need us to assist further!

If authentication is disabled in SpamFilter, then SpamFilter will not advertise that it supports authentication in the EHLO response. Per RFC, this should prevent clients from attempting to authenticate.

If a hacker tries to authenticate anyways... SpamFilter is simply sending to NULL the username/password and will simply ignore the auth request (but we are logging the attempted username/password in the logs so admins can see what the hacker is trying to do...).

Yapadu,

FYI a patched build (v4.7.4.250) is now available for download in the registered user area. Thanks for the report!

Uhm.. we're actually going to classify thit as a bug - if SpamFilter is not configured to use authentication, then your PCI guys are right - we should not advertise it being available.

We should be able to have a patch ready within the next 24/48 hours.

Is there any INI setting to disable SpamFilter from announcing SMTP Auth?  We don't have any users sending mail through our server with authentication.

Some PCI compliance guys are making noises that our server is advertising SMTP Auth, since we don't use it we might as well just stop announcing it.
