Android Code Snippet [B4X] SMTP Errors

Hello team,

I have lost three days in order to find out how SMTP library works with SMTP services(smtp2go, Sendpulse etc...) without errors about RCPT and more....

Private SMTP As SMTP

SMTP.Initialize("mail.smtp2go.com",587,"username","password","SMTP")

SMTP.Subject = "Subject"
SMTP.Body = "Body"

SMTP.To.add("recipient@mail.com")
SMTP.MailFrom="sender@yourdomain.com" 'DO NOT FORGET TO ADD YOUR DOMAIN SENDER MAIL
SMTP.Sender="sender@yourdomain.com" 'DO NOT FORGET TO ADD YOUR DOMAIN SENDER MAIL

SMTP.StartTLSMode = True

SMTP.Send

Wait For SMTP_MessageSent(Success As Boolean)
Log(Success)
If Success Then
    Log("Success")
Else
    Log("Error sending email")
    Log(LastException.Message)
End If
