Whats is port used for SMTP connection for Gmail Auth workflow?

Question

Hi Rebex Team,

What is the port used to establish a connection internally by Rebex SMTP auth workflow? Since during establishing the connection we only specify the SMTP server details.

The way connection is established for SMTP OAuth flow:
client.Connect("smtp.gmail.com", SslMode.Implicit);

Since you used SslMode.Implicit the port used is 465.

Please, check out Smtp.DefaultPort, Smtp.DefaultImplicitSslPort and Smtp.AlternativeExplicitSslPort properties to see other common port values.
