SMTP server responsible for sending outgoing e-mail messages. SMTP settings are required for the following Fax Voip FSP function:
It is assumed that you have an e-mail account, received from your Internet service provider or system administrator. Caution! To avoid unexpected problems this account should not be used by other e-mail clients to receive and send regular e-mails.
Select this option, if you want to use Collaboration Data Objects (CDO) for Microsoft Windows 2000 (Cdosys.dll) to send e-mails from Fax Voip FSP. Use this option if your SMTP server requires Implicit SSL connection (usually on port 465). You also need this method to send digitally signed e-mail messages.
If this option selected, .Net Framework method is used to send e-mails. Use this option if your SMTP server requires Explicit SSL with sending STARTTLS command (usually port 587 or 25 used). You also need this method to ignore error if your SMTP server does not have valid SSL certificate.
Sender’s e-mail address
Specifies the e-mail address that Fax Voip FSP uses to send e-mails. When Fax Voip FSP sends message, this e-mail address appears in the From box of the outgoing message.
Specifies the friendly name associated with e-mail address used by Fax Voip FSP. When Fax Voip FSP sends message, this name appears in the From box of the outgoing message. The default name is Fax Voip FSP, but you can leave it blank. In this case, the Sender’s e-mail address will be displayed in the From box instead of the name.
Specifies your SMTP server for outgoing e-mail messages.
Specifies the port number you connect to on your outgoing e-mail (SMTP) server. This port number is usually 25. In the case of using Implicit SSL connection port number is usually 465. If Explicit SSL with sending STARTTLS command is used, the port number is usually 587 or 25.
My server requires a secure connection (SSL)
Specifies whether to use the Secure Sockets Layer (SSL) security protocol when connecting to the SMTP server. The administrator of Internet service provider for the server will indicate if the SSL requirement exists. Please note that starting from Fax Voip FSP version 4.1.1, TLS version 1.2 is used in the case of secure connection (SSL). Previous versions of Fax Voip FSP used TLS version 1.0.
Select this option, if your SMTP server requires Implicit SSL connection (usually on port 465). With this method an SSL session is established up front before any protocol commands are sent. Using this method the error is generated if your SMTP server does not have valid SSL certificate. Implicit SSL mode is implemented via CDO.Message method of sending e-mails.
Select this option, if your SMTP server requires Explicit SSL (usually port 587 or 25 used). In this mode, the SMTP session begins on an unencrypted channel, then a STARTTLS command is issued by the client to the server to switch to secure communication using SSL. This method ignores error if your SMTP server does not have valid SSL certificate. Explicit SSL mode is implemented via System.Net.Mail method of sending e-mails.
My server requires authentication
Check this checkbox, if your SMTP server requires authentication.
Specifies your SMTP account name. This is usually the same as the part of e-mail address to the left of the at sign (@).
Provides a space to type the password assigned by your Internet service provider.
Send digitally signed e-mail messages
Adds digital signature to all messages that Fax Voip FSP sends. If messages signed, recipients will be able to determine if a message is really from you. The valid digital certificate suitable for the specified Sender’s e-mail address must be installed into the Local Machine Certificate Store on your system. The Network Service account, under which Windows Fax Service is started, should have read access permissions to your certificate private keys. The recipient does not need a digital ID to view signed messages.
A clear signed message separates the digital signature from the signed data. Non-S/MIME-enabled e-mail clients can read only clear signed messages. Use this option, when you don't know the recipient's S/MIME capabilities.
Specifies whether digitally signed message should be encoded to help avoid tampering with the signature. If this option is on, users of e-mail programs that do not support S/MIME will not be able to read signed messages. When you do know that a recipient has S/MIME capability, you can use either clear or opaque signing.
Click to display a dialog box that contains the properties of an X.509 certificate and its associated certificate chain. If valid certificate associated with specified Sender’s e-mail address not found, the information message is displayed. The valid certificate must be installed into the Local Machine Certificate Store on your system. The Network Service account, under which Windows Fax Service is started, should have read access permissions to your certificate private keys. If your certificate is installed into the Current User Certificate Store, Fax Voip FSP proposes to install it into the Local Machine Certificate Store. If your certificate is installed into the Local Machine Certificate Store, but Network Service account does not have read access permissions to private keys, Fax Voip FSP proposes to grant read access permissions to private keys for fax service (Network Service account). Follow the instructions of the dialog boxes. Please note, that administrator privileges are required, to check access permissions for Network Service account and to install the certificate into the Local Machine Certificate Store. See more details in the To obtain and install secure e-mail certificate chapter of this user manual.
