ServerPort Property

Listening port of SMTP server.

Data Type: Long

Remarks

25 port is the default SMTP server port to receive email. However, some ISP block outbound 25 port to prevent user to send email directly to other SMTP server. Therefore, many email providers also provide an alternative port 587 to receive email from such users. 465 port is the common port used to receive email over direct SSL connection. If your server uses 465 port, you must set ConnectType to ConnectSSLAuto.

Example

[Visual Basic 6.0, C++, JScript, Delphi] The following example demonstrates how to send email with EASendMail SMTP Component, but it doesn't demonstrates the events usage. To get the full samples of EASendMail, please refer to Samples section.
