Hi, guys...

James, have a look at the domain report from mxtoolbox.com. I see a few issues, including a mismatched RDNS PTR / SMTP banner. The source of your trouble is likely there, in the DNS records and some bit of CGP configuration.

I've been watching for signs of similar failures over here, particularly as we're both running 5.4.10 (or close), but have not seen anything. Sorry for the slow follow-up.

Cheers

It's pretty usual for MTA's to complain about the identification in HELO or EHLO not being correct (no fqdn, RFC1918 IP as in this case, PTR doesn't match name, etc.). On the global internet, "[10.0.1.20]" is, in fact, not a client's name.

But in any case the text after the 250 code shouldn't matter at all. From RFC 5321 (4.2): "The number is for use by automata to determine what state to enter next; the text is for the human user.", with given exceptions being response codes 220, 221, 251, 421, and 551.
