This happens every time I try to send an email using the PHP mail() function (from /var/log/maillog): Code: Oct 17 17:44:01 server1 sm-mta: i9HFNwfp080034: to=<email@example.com>, delay=00:20:02, xdelay=00:20:02, mailer=esmtp, pri=30893, relay=mx4.hotmail.com. [184.108.40.206], dsn=4.0.0, stat=Deferred: Operation timed out with mx4.hotmail.com. Same thing happens with gmail.com, wanadoo.nl addresses etc etc. php.ini is configured properly, sendmail seems to work ok, so I guess it's some setting in the OS, but where? Can anyone help me? I got it to work before on a FreeBSD 4.9 machine, so I am kinda frustrated now, since I copied/pasted the PHP code from a script I worked with before.
