; XAMPP IMPORTANT NOTE (1): If XAMPP is installed in a base directory with spaces (e.g. c:program filesC:xampp) fakemail and mailtodisk do not work correctly.
; XAMPP IMPORTANT NOTE (2): In this case please copy the sendmail or mailtodisk folder in your root folder (e.g. C:sendmail) and use this for sendmail_path.
; 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:xamppsendmailsendmail.exe" -t"

; XAMPP: Comment out this if you want to work with mailToDisk, It writes all mails in the C:xamppmailoutput folder
;sendmail_path="C:xamppmailtodiskmailtodisk.exe"
