Forms not sending confirm emails! Please Help ASAP!

SOS! All of a sudden no forms on site will send emails with info gathered

[chicoco25]

I have set up various forms for the website i do updates for. There are various forms set up to send:

1) a confirmation email to the person filling out the form
2)Send the results to an outside company for billing
3)Write the results to a database located on the server for logging

For some reason, all the forms(or at least the ones Ive checked) have stopped sending the confirmation and the email to the outside billers. The only thing still functional is the writing to the database...and the 'Thank you' page that comes up after submission of the form. Most of the forms havent been touched recently, so im assuming its a bigger problem. PLEASE PLEASE PLEASE...if you have any suggestions, please share. What could the problem be?!

Is the sendmail daemon running?

[chicoco25]

nothing happens at all. the emails just never send. Any clue?

I'd make sure that your sendmail daemon is running, check the mail log (it's probably in /var/log/mail.log or close), see if you can send mail yourself from that machine, check the mail queue (probably in /var/spool/mqueue), check your webserver error logs (probably like /var/log/httpd/error.log or some such), and look around a bit. If you need to rent a system administrator, you can probably find one on one of those freelance project sites. I know I used to do a lot of jobs on them. If you share your machine, inquire with the people that you rent it from or whatever.

I had a similar problem and my ISP advised me to delete the whole site from the server and then re-publish, which worked fine. They never explained why, but to be honest I was losing so much money until it was fixed that I didn't really care.

What scripting language are you using to process the form information?

If your host upgraded their PHP, your problem could lie there(if you are using PHP). They may have configured it differently.

...especially if you relied heavily on register_globals :o
