I'm having a problem here I hope you can help with, I've got a web server using iis6 and php, php config is setup to use my sbs2008 SMTP server to send email.
My problem is that about 7 times out of 10 the email fails but sometimes it works fine. I've actually got owncloud setup but when it comes to sending an email its very intermittent.
I know this is nothing to do with Owncloud as ive got a small php mail test script that just sends emails - cloud.codeman.org/mailtest.php but you will see sometime i get 500 error and sometimes test email sent, driving me crazy :-x
I wonder if there's a way to diagnose what's happening or if someone has seen this before.
Cheers Mark
PS im using Windows 7 IIS6 with PHP and sending mail to SBS2008 using SMTP to pass to my website host to get the mail to the outside world.
