SMTP server configuration - authorization

From the safety reason, the server smtp.forpsi.com requires valid authentication. In addition, sender's domain must be the same as domain used for authentication or this domain's alias.
 
  • Authentication
SMTP server requires authentication. You need to enter correct username (email address) and password to be able to send any message through it. If you don't set using authentication for your email account, the email client will return the following error message.

MS Outlook:
Task 'john.smith@domain.com – Sending' reported error (0x800CCC78): 'Cannot send the message. Verify the e-mail address in your account properties. The server responded: 550 5.1.0 piWs1j0010jifNx01iWsdh authentication failed'

Thunderbird:
An error occurred while sending mail. The mail server responded: 5.1.0 piWs1j0010jifNx01iWsdh authentication failed. Please verify that your email address is correct in your Mail preferences and try again.

Opera Mail:
 Internal error [550 5.1.0 piWs1j0010jifNx01iWsdh authentication failed]

The error messages display the servers' response:
 
 5.1.0 piWs1j0010jifNx01iWsdh authentication failed

What to do when you get this error message: go to your email account settings and check it, the instructions for setting up each email client are described in the section Email clients (in Czech).
 
  • Sender's domain must be the same as domain used for authentication or this domain's alias
The SMTP server is included in the webhosting service offered by our company. The webhosting is pointed to a particular domain or its alias. For these reasons, you are allowed to send emails only from the domains with ordered webhosting. Sending emails is not allowed in these situations:
  • You use as your email identity a domain which doesn't have webhosting provided by our company (for example Hotmail or Google mail account).
  • You use as your email identity a domain provided by our company, but you don´t authenticate to its SMTP account .
The SMTP server will return this error message:
 
 5.1.0 <john.smith@domain.com> sender rejected

If you need to send an email with sender somebody@gmail.com, please use SMTP server provided by Google provider.

The same limitation is used for 3rd level domains, even if they are hosted by our company.

What to do if you get this error message: go to email account settings and check it, setting for each email client is described in the section Email clients (in Czech). The same error message is returned when the smtp connection is rejected by GeoIP protection - see bellow.

Note: our webmail allows you to configure 4 external accounts and to set one alternative sender's address. These email addresses can be used as sender´s addresses, although they are not hosted by our company nor are they aliases of domain used for authentication.
