Hi,
First of all I'm using this on a dedicated server where all php & apache setting are good and set to accept large files to be uploaded on my server. Everything is checked.
At first I set the limit at 100MB but I couldn't get any error message, I only got the spinning gif, nothing was send. I tried to send 5MB it succeed, then I tried 10MB, and now I have this error message :
Failed to send your message. Please try later or contact the administrator by another method.
I got nothing in my system log. I just know that the script return false for MailSent.
Where should I look now? :/
