I'm very sorry but I'm really shocked to find that this host too doesn't support the PHP mail() function, just like it was in the
old DPForums (altho it was a different host).
So I'm trying to figure out ways to enable it, also tried to contact the Support. They mostly disable it to prevent spam abuse. But due to that, the forums won't be able to send any mails at all. But fortunately this forums system has an option to disable mails overall, hence atleast until I find a solution, u won't be getting those weird
emailer.php, SMTP errors.
But anyways, atleast the forums are back on, so I think having no email service for sometime is better than not having the forums up altogether.
