To send emails via the SMTP protocol, you need to set the SMTP server address in your email client, in the form smtp.testovacidomena.cz
You can find the specific SMTP server address for your web hosting in the service activation email or in the customer center (zákaznické centrum) in the detail of the specific web hosting
You must use authenticated login to the server. Choose one of the methods supported by your client (preferably an encrypted password; Kerberos / GSSAPI or NTLM CANNOT be used). For authentication, use the name and password of your mailbox (the same details as for POP3 or IMAP).
We also recommend setting up a secure connection using SSL/TLS or STARTTLS, so that communication between you and the server cannot be eavesdropped on.
