config assistance [errno.ECONNREFUSED]

[Philippe LeCavalier]

Hi All.

It's been ages since my last post. Truth is, I dropped oli some time ago
due mostly for my lack of ability in troubleshotting issues in sup
mail(my one and only reason for using oli). I'm trying to get back into
sup and oli because despite my aforementioned lack in self-help I was
still more effecient than with a gui MUA...That said, I've ran into a
really basic issue in configuring oli...Here's[1] the output I'm seeing
after creating my offlineimaprc[2]. I suspect this has something to do
with my shared hosting enviro in that the host doesn't implement true
certs so perhaps it's failing that process. -although based on my
knowledge of oli it doesn't actually check certs I think!?

I'm running Debian in mixed stable/testing (Squeeze/Wheezy). Here[3] are
some relevant pkg versions.

Thanks in advance,
Phil
