iOS Question sending mail smtp

[Jorgelcr]

Hello,
I have the following code for b4a and it works fine.
I have implemented it in b4i and it does not send mail.
It gives me an error:
unsupported login mechanism

SMTP.Initialize("smtp.serxxx.es", 465, "[email protected]", "xxx", "SMTP")
                
SMTP.UseSSL=True
SMTP.StartTLSMode = False
SMTP.To.Add([email protected])
                
SMTP.Subject = "Registro APP"
mensaje="Bienvenido "
                
SMTP.Body = mensaje
            
SMTP.Send

can anybody help me?

This means that your email server uses a login method not supported by the underlying library. It supports "PLAIN" and "LOGIN" methods.

Net library for Android is not absolutelly equal to iNet under IOS. For example, under B4A there is AuthMethod unlike B4i

Try to set SMTP.DebugLogs = True and look a log. For example, for my mailserver:

C: Attempting to connect to server at: ***
S: 220 *** ESMTP MailEnable Service, Version: 10.25-- ready at 09/14/20 17:48:35
C: EHLO localhost

S: 250-***, this server offers 5 extensions
S: 250-AUTH LOGIN
S: 250-SIZE 40960000
S: 250-HELP
S: 250-AUTH=LOGIN
S: 250 STARTTLS
C: AUTH LOGIN
***

At least, it's visible, what a mail server supports.

is there any solution?

First step is to find which authentication methods are supported by your email server. If you have control over the server then enable one of the two methods posted above.

Suppose my server supports 250-AUTH LOGIN how to proceed for sending?
thank you

Ho risolto utilizzando
SMTP.StartTLSMode=False
