Hi, I have a MAJOR problem with PHP mail() function, one that is odd and very frustrating as I have no idea what is causing it. I have used the one script to send emails out in the past and they have been sucessfully sent out, but as of a few days ago and now they are bouncing, some are actually being sent and some just simply won't go out. So let me explain. I have an admin area of my site where I have all users in a mysql database. Their email address, names, address, etc. The admin side allows me to do many tasks like send out text-based emails via PHP mail() function and HTML emails. What it does is I type in the field boxes and saves to a mysql table, than I run a cronjob to grab the email data and email addresses and send out using PHP mail(). The script worked fine in the past, no problems but now I get the following message when I attempt to send emails: --- This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: USEREMAIL@xxxxxxxxxxxxx unrouteable mail domain "cashgrace.com" --- But that's not all, it comes up as that for all domains, like yahoo.com, hotmail.com, bigpond.com etc... All of them, even though they are reachable via webmail. I can go into webmail via CPANEL and send emails and they actually go to the person, so does not seem like a mail server problem or does it? I beleive, but could be wrong, it is somewhere in the mail() function on the root part of the server. But of course I don't have access to it. But the weird thing is this... Some emails 1/10 do actually get sent and delivered, do not bounce, but the other 9 fail. Why? Well I did some more investigating... Well for what I have access to. The Server Load for the Server was flashing RED in the Server Status area. So I persume this is bad? Maybe due to this maybe it's attempting to send emails but looping and not got enough resources to actually do the job and in the end gives up and produces the bounced email? As I said before I could be way off track but worth suggesting and trying to figure it out. Is there a way to DEBUG my mail() function I call in the cronjob? The joy of the CRONJOB is that it's written in PHP also, so I can view it on a webpage. So if there is a way to DEBUG it I should see where the error is? Or won't I? Any suggestions? I've looked long and hard, emailed my admin and they are optimistic with the problem also so thought I'd post here and see what can be done and if we can get some outside help. As I said before the script for the mail() has NEVER been changed. So it can't be my code as it has worked in the past. Must be server side somewhere... Unless my admin has done an update and something has gone wrong. But I thought someone on here would know what could cause the error, at least we can investigate it instead of having no idea what is causing the problem. All the help is needed here if people can provide it. Thanks in advance, and sorry for the long email. But this problem is really giving me the 'you know what' now.
