RBL checking before SMTP auth for remote POP/SMTP users

Just curious, does anyone know if this is still the case where the GWIA will reject a SMTP connection based on the RBL's before a user is able to authenticate?

Yet if we point the SMTP to GMAIL it works OK, so Google obviously don't Black List consumer broadband subnets.

The reason I wonder is that I have a situation again where a user working from home (on a consumer broadband plan) is being rejected from sending SMTP email via their office GWIA.
To get around this in the past, I have configured a second GWIA on a say port 26 that only accepts authenticated SSL connections, and instructed remote staff to send via this GWIA.

    Yes, that's still the case.

    Of course they don't, it would invalidate their whole product, which is
    designed to be used from such subnets.

    Another, much more functional option is of course to open up the POA
    ports to the outside and let your remote users use the groupwise client
    instead of pity POP/SMTP.

    I agree totally about the groupwise client. It works so well in or out the office, and so simple to setup.
    However this user is using Mac mail and wants all their email in there, so second GWIA it may be.
