Hello,
yes, you are correct, there are settings for the outgoing mail's stuff, I've set them to the exact same like on the original site, so basically the same e-mail, same login, same port etc. but for some reason the outgoing mails are working on the original site but on the copied one they won't.
As far as the DNS case goes, I honestly have no idea how the hell and where the hell the DNS settings are located, can't find them anywhere, additionally most of the .php files on my FTP are unaccessable - by that I mean that by opening them using a WordPad/Notepad - there's just random ****load of strings that I have no idea what these strings mean.
The copied site is hosted on the same FTP as the original one (same FTP server, different folders/directories obviously). What mail method am I using? Honestly I have no clue, I can send you a screenshot of the settings I've got in my control panel of the site (bear in mind it's in Polish tho):
