Yes, but I got the gist of it.

Thanks again.

The reverse DNS ptr for 216.110.252.42 is mail.dcwebsolutions.ca so that is ok.   But I don't know where I could check my SMTP Banner.

Presumably they mean that your server introduces itself as dcwebsolutions.ca rather than mail.dcwebsolutions.ca in the SMTP session. You can set it to mail.dcwebsolutions.ca by changing "Identify myself as" in MercuryE configuration. (It will probably not be a problem to keep it as it is if you would prefer that, though.)

That's it

Thank you

Actually I was a bit too quick to click Post. There are separate settings for incoming and outgoing connections, so for incoming connections the corresponding field is "Announce myself as" in MercuryS configuration.
