We are receiving some errors and specifically when submitting a form, the form does not send an email:

Message:Padding is invalid and cannot be removed.

StackTrace:

Looking the SMTP portion (because it's referenced in the log), I went to check our STMP settings. If I try to update them, I get the following:

Hello Dave... Welcome to the forums! What module/feature are you using to send email? Is it only the SMTP feature where you've tried it?

Is the error you posted directly a result of the SMTP view you've highlighted, or from a module? Are there any other related errors in the logs?

What SMTP service are you trying to use? Does that also have any logging that you can look into?

I believe the module is called Forms and Lists. However, no mail seems to work. As an example, when adding a user to a role in the DNN settings, we receive errors as well. This leads me to believe the root cause is the SMTP setup.

The SMTP page you see there is in Settings - Servers - Server Settings. I am unable to enter any SMTP information because that last screenshot comes up every time I leave that screen and come back (even if I try to save, it is blank when I come back).

When I look at the logs immedately after going to that page, it appears it's once again related to some padding issue:

What version of DNN are you using?

Are you able to see the SMTP settings at all before you attempt to update them? What SMTP provider are you trying to use?

If you're not able to see those values, you can run the query below against the database to see what they are.

SELECT * 
FROM [dbo].[HostSettings] 
WHERE [SettingName] LIKE '%SMTP%' 
ORDER BY [SettingName];

SELECT * 
FROM [dbo].[PortalSettings] 
WHERE [SettingName] LIKE '%SMTP%' 
ORDER BY [PortalId], [SettingName];

Good morning,

DNN V 9.12
No, the settings aren't in the UI at all. I immediately get the error at the bottom of my first post.
The data is in the database.
The provider is an internal SMTP address (I think that's what you're asking).

One additional piece of information is that we migrated to a new server in the fall. The odd part is that everything else works except the email piece.

Make sure you have a row for SettingName = 'SMTPmode' in PortalSettings for the primary portal, and the SettingValue = 'h'. That setting is the one that sets the 'global' option. If you don't have that, you will get the error you see about not being able to load the SMTP settings.

Also, post your 'SMTP*' settings from HostSettings and PortalSettings tables, obscuring the credential/server values, of course :)

Updated that (was a p) but same result (also did an iisreset to make sure the app reloaded)

Through all this back and forth, you guys helped me narrow down the issue. I think I figured it out. I basically used SQL to update all of the SMTP settings back to blank. Now I am able to load the SMTP settings page and a test email worked!

Thank you very much
