INetSmtpClient

Description

The INetSmtpClient interface contains properties and methods for email messages sending using the SMTP mail service built in Windows.

Comments

The SMTP client described with this interface enables the user to send emails to the mail server, which address is specified on initializing of the SMTP client in the NetSmtpClient.CreateWithHost or NetSmtpClient.CreateWithHostAndPort constructor. The mail server relays an email to other mail servers according to the information about recipients. If authorization is required, it is necessary to specify appropriate credentials at the mail server in the ThisHostCredentials property.

If required, mail server and port information can be changed in the Host and Port properties. After that SMTP client can be used again to send any emails.

NOTE. If SMTP server is accessed from the local network via proxy server, it is required to check if access permissions for the SMTP server port in use are contained at the proxy server.
