iOS Question SMTP AUTH_LOGIN

[mmieher]

Erel,

Any plans to implement this in B4i? I apparently need it to log on to our Exchange Server. This works in B4a:

        SMTP1.StartTLSMode = True
        SMTP1.UseSSL = False
   
        SMTP1.AuthMethod = SMTP1.AUTH_LOGIN

It should choose this authentication method automatically based on the server response. Do you get any error message?

 

[mmieher]

Yes --

<B4IExceptionWrapper: Error Domain=NSOSStatusErrorDomain Code=-9807 "(null)">

Here is the code:

   ' SMTP1.Initialize("smtp.gmail.com", 465, "[email protected]", "password", "SMTP")
    SMTP1.Initialize("owa.wvhops.com", 587, "[email protected]", "password", "SMTP")
   
    'SMTP1.UseSSL = True
   
    SMTP1.StartTLSMode = True
    SMTP1.UseSSL = False
   
'    SMTP1.To.Add("[email protected]")
    SMTP1.To.Add("[email protected]")
'    SMTP1.BCC.Add("[email protected]")
    SMTP1.Subject = "Spot Hops:  INCOMING!"

Does your mail server support non-ssl connection? If yes then try it on the non-ssl port. This issue might be related to an unknown certificate.

 

[mmieher]

As far as I can tell, Exchange Server 2016 insists on TLS.

 

[Erel]

Is it accessible over the internet? If yes then you can create a temporary account for me and I'll test it.

Thank, Erel.

The server is owa.wvhops.com. Your user is "[email protected]".

I know the email domain and server domain names are different. Long story.

I tried various settings and all of them failed. I was able to get a bit further by disabling the SSL verification but then it failed with a different error (504 5.7.4 Unrecognized authentication type).

If you have access to the server configuration you can try to disable chunking and binary mime: https://adaptivethinking.wordpress.com/2010/12/21/smtp-esmtp-and-the-bdat-baddie/
It might be related.

Thanks, Erel. How did you disable the SSL verification? Change port 587 to 25 and do not StartTLS?

 

[Erel]

How did you disable the SSL verification?

I've disabled it in the library code.
