Hi,
I admit it's not a new kernel, But I'm running Slackware 8.0. The 2.4 kernel that comes with it was apparently buggy 😛
I have further info that may help to crack this case.
In a flash of brilliance (shakes head), I decided to look at the logs and found this entry just after I ran the test script:
Jan 27 18:43:54 metabelis sendmail[8982]: h0R7hs6n008982: from=nobody, size=56, class=0, nrcpts=1, relay=nobody@localhost
Point is, I think sendmail is blocking said address as it is not an FQDN. Problem, sendmail is servicing an active mail server so I can't really open it up.
php.ini seems set up ok, Apache is set up ok... (meaning no nobody@localhost references)
Question I have is, where is it getting nobody@localhost from?
If I can change this, it might just work...
