Currently, I am attempting to integrate the SMTPClient object into my application using PB 2022 R2.

Our SMTP server does not require a username / password if you are inside the firewall. I cannot seem to get the 

object to send an email successfully without providing values  in these 2 attributes :

 

smtpclient.Username and smtpclient.password

 

Is there a way to tell the object that no pwd / username is required ?

Hi Miller;

  This is a known bug in the SMTPClient that will be fixed in the next upcoming PB 2022 R2 MR See ticket #10785, 10806.

If you look at ticket #10785 though, you will see that there is a downloadable "hot fix" available for this limitation if you would like to try it.

HTH

Regards.. Chris

Here is an update.

 

I have been able to get the SMTPClient to send emails without credentials with the Hotfix applied.  However, this will only work if I send email to people

on the same domain.

The moment I try to send to gmail or any outside domain then credentials must be used again.

I noticed that C# has an SMTP client object that has a UseDefaultCredentials attribute. I used SnapDevlop to play around with some code using that object 

and it basically passes through my credentials without exposing them.  I wonder if we could do something similar..

Hi Chris,

 

I can just use the userid and password with the Hotfix taken out.  I did get this data when I used the SendAsync()

Are you using the Send() or the SendAsync() command?   I have tried using both

Is your system using a Proxy Server (ie: SetProxy command required)?  I am currently not using a Proxy server

Thanks for that update!

Note that the hot fix might still be too early a fix for every environment and may still need tweaking by Engineering.

Please open a support ticket for this issue and also reference ticket # 10785 for Engineering to investigate further.

In the mean-time - even with the hot fix - does using the UID & PWD still work as a workaround?

I added the Hotfix and simply commented out the 2 lines that set userid/pwd and now I get this error :

 

-13 Failed sending network data.

 

My sends were working with the userid and pwd before implementing the Hotfix
