Phil will know better but I wonder if the reverse DNS authentication is
on?
host_lookup = *
If you have not got DNS set up nicely in /etc/hosts and /etc/resolv.conf
this will prevent that.
Sending to IP addresses is particularly probelmatic. I worked for an
ISP and we were supposed to have reverse DNS set up on all out IP
addresses. We didn't. And as far as I know, a lot of sloppy practice
like that still goes on.

Why not make this easy for yourself? Go to
www.dhis.org, have a name
assigned to your machine and even if your machine changes IP address,
you can email, ssh, ftp, etc. For example, I can always be reached on
pkirk.net.dhis.org even though I get a different IP each time I connect.
Of course, there may be a simpler explanation with a workaround Phil
know about.
