Warning: tempnam() [function.tempnam]: open_basedir restriction in effect. File() is not within the allowed path(s):
If you care, this message goes away for me if I change
if (getenv('TEMP')) $tmpFile=tempnam(getenv('TEMP'), 'postie');
sorry if this is redundant. I did search for open_basedir but got many responses none applying to Postie as far as I could see.
