DNS Report Failure - MX Records

[Black20VT]

Hi,

I've just introduced greylisting and the ELHO/HELO delay and carried out a DNS Report and my backup rollernet MX records seem to be failing for some reason.

Here's the result:

- - -

FAIL

Connect to mail servers

ERROR: I could not complete a connection to one or more of your mailservers:
mail.rollernet.us: The mailserver terminated the connection before the transaction was complete (state 8 ). This is not RFC compliant, and therefore either due to an error, or it may be the result of a non-RFC-compliant mailserver or non-RFC-compliant anti-spam program.

mail2.rollernet.us: The mailserver terminated the connection before the transaction was complete (state 8 ). This is not RFC compliant, and therefore either due to an error, or it may be the result of a non-RFC-compliant mailserver or non-RFC-compliant anti-spam program.

I'm sure it's nothing to serious, but any idea exactly what could be causing it and how I can fix it?

Thanks.

It appears I might have been a bit hasty.

I seem to have fixed it myself by adding a few email addresses to the whitelist and excluding them from greylisting.

All now seems back in order.

Apologies

I've noticed that the failure you noted only shows up if the response return is a 4xx "defer", such as from Greylisting or "defer all" mode. It's not really broken, but I suppose their parser doesn't like 4xx responses.
