    I was wondering about the following:

    I disabled SMTP on a VPS because I don't need it. The mails that are being sent out by cpanel/whm and php forms (user nobody) are still being accepted by cpanel servers that have sender/callout check enabled.

    Ofcourse it's a good thing these mails are not rejected, but I was wondering how does the sender/callout check work exactly in this case, since SMTP is disabled on the sending server?

    I had to enable SMTP again since it seemed to cause 'Connection refused' errors in certain cases.
    One other thing I noticed is that 'SMTP Tweak' (WHM -> Tweak Security) causes exactly the same issues.

    On the receiving server these entries showed up:

    2006-08-27 07:38:55 H=host.domain.com [xx.xx.xx.xx] sender verify defer for <root@host.domain.com>: could not connect to host.domain.com [xx.xx.xx.xx]: Connection refused
