I don't need help but you might want to correct this.
You are telling them to comment out what they want to use;
Currently:
; XAMPP: Comment out this if you want to work with fakemail for forwarding to your mailbox (sendmail.exe in the sendmail folder)
;sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
; XAMPP: Comment out this if you want to work with mailToDisk, It writes all mails in the C:\xampp\mailoutput folder
sendmail_path="C:\xampp\mailtodisk\mailtodisk.exe"
Should be:
; XAMPP:Uncomment the next line if you want to work with fakemail for forwarding to your mailbox (sendmail.exe in the sendmail folder) and comment out the line below sendmail_path="C:\xampp\mailtodisk\mailtodisk.exe"
sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
; XAMPP: Uncomment the next line if you want to work with mailToDisk, It writes all mails in the C:\xampp\mailoutput folder and comment out the line above sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
;sendmail_path="C:\xampp\mailtodisk\mailtodisk.exe"
