I have been using Jacks formmail.php which has been working fine, but then suddenly stops for no reason. I also use Matt's FormMail.pl. It also worked fine, but suddenly stopped working.
Failure to receive the formmail happens from time to time and then it suddenly starts working again. I have the mail configured to be sent to my domain email as well as gmail for a backup, but nothing is arriving. What could be causing this? Please don't say I have not configured them correctly because they work fine but just stop and eventually restart for no apparent reason, as I have changed nothing. I also cannot use DreamHosts formmail as an alternative because it does not work with SSL, https. Thank you.
