mail function intermittently not working?

[quixotic]

Anyone ever see this happen? I never see an error in the logs, the server seems fine, (no sudden traffic spikes etc.), but all of a sudden at random, PHP won't send out mail.

I realize it could be a problem with the script I'm running, Uber uploader, a perl script that returns values to PHP, or perhaps my configuration. I've set timeouts pretty high along with max post sizes etc, to accommodate large file uploads. But I am at a loss as to why this only happens to a few people and only at random times.

Still many issues you look into there. You have the mail server sending out the email that may have a problem. The email recipient might have issues, or perhaps the email was regarded as spam and trashed. So many problems could go wrong here. How often does it happen? If it's only every once in awhile I wouldn't be too worried about it. If the other way around, you might want to spend more time tracking it down and fixing it. :)

It's an odd one. All the header information stays the same, same recipient, same sender, same subject. The only info that changes is in the body, which just contains a small list of file names, and single line indicating the registered user who triggered the request.

The site owner relies on that email notification to start working on a users request. Without it, the user just assumes the owner is ignoring them.

It's completely random. Resending the same information from a failed attempt, always go thru (though I imagine if I sent it 1000 times, perhaps a few wouldn't).
