Refactor `DialWithContext` to delegate client creation to `SMTPClientFromDialWithContext`. Add new methods `SendWithSMTPClient`, `CloseWithSMTPClient`, and `ResetWithSMTPClient` to handle specific actions on `smtp.Client`. Simplify `auth`, `sendSingleMsg`, and `tls` methods by passing client as parameters.

// Send attempts to send one or more Msg using the Client connection to the SMTP server.
|
|
// If the Client has no active connection to the server, Send will fail with an error. For each
|
|
// of the provided Msg, it will associate a SendError with the Msg in case of a transmission
|
|
// or delivery error.
|
|
//
|
|
// This method first checks for an active connection to the SMTP server. If the connection is
|
|
// not valid, it returns an error wrapped in a SendError. It then iterates over the provided
|
|
// messages, attempting to send each one. If an error occurs during sending, the method records
|
|
// the error and associates it with the corresponding Msg.
|
|
//
|
|
// Parameters:
|
|
// - messages: A variadic list of pointers to Msg objects to be sent.
|
|
//
|
|
// Returns:
|
|
// - An error that aggregates any SendErrors encountered during the sending process; otherwise, returns nil.
