I've been using contact form 7 for a while now. I have 60+ forms for various uses. We rely heavily on this plug-in. It's been reliable and consistent for a long time (2+ years). Two days ago they all stopped working. I contacted the host and they stated:
The only change we made on the server is enabled " Prevent the user "nobody" from sending out mail to remote addresses " since people were abusing the server sending out spam. PHP and CGI scripts generally run as nobody if you are not using PHPSuexec and Suexec respectively.
Does this make sense to any of you? They are unsure wether or not their change is the cause of my issue, but the change they made and the timeline they made it on make me pretty sure they are the cause of this massive failure. If this is the case. I doubt they are willing to roll back their changes to the server. This means I have to find a way to stop Contact Form 7 from sending emails as anonymous.
They also stated this:
Well, from the beginning you are not suppose to use " nobody " as user, this will open doors to spammers. But, we're not even sure if this is the case. The best thing to do is contact your webmaster, maybe the script needs to be updated, if you haven't updated in several years.
I do not see any errors on the server. If you can provide me an error and if this is a problem on the server side, I will have an administrator fix it.
