B4J Question SMTP send mail issue from outlook

[teddybear]

I configured IMAP and SMTP in a third-party mail client as required by outlook，It works well.
In B4j I use same way to set SMTP, it does not work, my code is

    SMTP.Initialize("mailserver", portnumber ,"example@hotmail.com" , "password", "smtp")
    SMTP.Subject = Subject
    SMTP.Body = Body
    SMTP.To.Add(MailTo)
    SMTP.StartTLSMode = True
    SMTP.Send

error is

Program started.
SMTP Initialize Done

eMail Failed to send - To: xxxxx@xxxxxx.xxx Subject: subject test1

I searched for the issue on the forums and found 2 threads(thread1 and thread2) that same issue, Both of them seem to have solved the issue. I downloaded the example （v0.4) of thread1 in post #33 and it does not work yet.

Perhaps this could help you, this is working for me:

    SMTP.Initialize("smtp.outlook.com", 587 ,"example@hotmail.com" , "password", "Mailer")
   
    Dim M As Map
    M.Initialize
    M.Put("Content-Type", "text/html; charset=utf-8")
    M.Put("Content-Transfer-Encoding", "7bit")
    smtp.AdditionalHeaders = M
    
    smtp.StartTLSMode = True
    smtp.UseSSL = True
    smtp.Sender = "<" & "example@hotmail.com" & ">"
    smtp.To.Add("destination@to.go")
    smtp.Subject = $"Test $date{DateTime.Now} - $time{DateTime.Now}"$
   
     smtp.HtmlBody = True
'    smtp.Body = "This is the body text of the email"
'    smtp.Body = File.ReadString(File.DirApp,"test1b.html")
    smtp.Body = CreateHtmlBody
    
    Dim trustall As CustomTrustManager
    trustall.InitializeAcceptAll
    smtp.SetCustomSSLTrustManager(trustall)
    smtp.AuthMethod = smtp.AUTH_LOGIN
    
    smtp.Send

Sub CreateHtmlBody() As String
    Dim HTML As StringBuilder
    HTML.Initialize
    ' Your HTML text
    HTML.Append($""$)
    Return HTML
End Sub

It has been quite some time since I made this program code under B4J. If I remember correctly the challenge was the extra mail header and the SSL. The outlook.com port number you should use is 587.

Thanks a lot for your help. Your code works well
