I'm confused again.
Here is what the isp sent to me from their logs...
2025-07-23 10:46:43 H=dudl [snip details] .virginm.net (iMX6-1)
[82.34.xx.xx] F=bob@somewhere.org.uk rejected RCPT rcomp@rcomp.co.uk:
R1: HELO should be a FQDN or address literal (See RFC 2821 4.1.1.1)
So I looked at the RFC. It says either an ip address in square
brackets or an FQDN.
Mine is/was just iMX6-1.
So my reading of that is it should be either:
[192.168.1.31] Can't be a WAN address that changes quite a bit and
it seems to need to specify the machine which the
Wan address can't do due to NAT. On the other hand
the LAN address is irrelevant to anything on the
WAN.
or
iMX6-1.somewhere.org.org.uk
Why can't articles be clear what they mean by IP address !

That article suggests its the WAN IP address it's after. Grrrr.
Sorry but what do you mean by local IP address? Lan or Wan?

Right so we don't touch the OS settings just the smtp setting in
Hermes for that account?
I'll give that a spin over the next day or two. Bit sick of it at the
moment.

Oh no. Please make it stop !!
Thanks,
