server: mail.symbion.hu
server: smtp.symbion.hu port: 25, 2525
2525 is preferred on mobile machines, because TCP port 25 is blocked on many networks. SMTP authentication is required, please ask for login/password.
For compatibility reasons port 2525 on mail.symbion.hu is also redirected to this service, but it is deprecated, you should not use it. You have been warned! :)
