Hi. It seems there's a problem with email confirmation on our wiki (http://dragon-mania-legends-wiki.mobga.me/Main_Page). Everytime I try to have a confirmation code emailed, I get this error:

Dragon Mania Legends Wiki could not send your confirmation mail. Please check your email address for invalid characters.

Mailer returned: Unknown error in PHP's mail() function.

And I am not the only one getting it. Is there any solution to it?

Have you tried contacting the people who run the wiki?

Also, you should ask your question on that site's forum.

I am one of the people who run the wiki.

Turn on the debug log and see if it tells you anything more about the error.

No such file was generated in that folder, but I did find some mail log files in var/log and the most recent one had these lines: http://pastebin.com/mPsdcJJH I googled the error, which lead me to using dpkg-reconfigure postfix, but I get stuck at the terminal. As in, I have no idea what to configure. This is what I see: http://prnt.sc/e5mnpm

You should set up the system as an internet site.

You might also try "sudo apt-get -f install".

Setting it up as an internet site worked. Thanks a lot!
