Wing FTP Software

Hi

I'm a new user of wing ftp server !
I set up a smtp configuration and when i test it, it's OK.
but when I use weblink and i put a email adress outside my exchange server I have a an error
"Mail to xxxxx@gmail.com" rel="nofollow failed, send header to server error"
but if a I use a email from my domain it's work

I try to find an answer on the forum but I find nothing

Thanks

Thomas

I solved the problem
You must add on the smtp connector the ip adress of your wing ftp server on transport Hub

Thanks
