My site SMTP email seems to work fine...  When I "Test SMTP Settings" - email is sent and I receive the notification in my email client.  THe mail server seems to be working.  I also tested the forum and other modules that use email and it works.

However I needed to send an email to my membership via "roles" - so I thought I'd try the Newsletters module... for a test I sent a message using "Additional Emails"... the module reports:

Bulk mail sent (asynchronous mode). Please check confirmation email for result.

The notification email says "There is a problem with the configuration of your SMTP Server. Mail was not sent."  - and I did not receive the email from the Newsletters module.

I went to Host Settings > Logs and here is an example item:

My host email account is admin@domain.com - its the superuser address - which is what I'm using when trying to get this to work - and it is in the host settings as well.

Ideas?

working site email is less usual than working host smtp.
However, for DNN 7.4.2, there is a change, using now host email address from Host Settings as Sender.
Which DNN version are you using?

I remember a couple of issues with site specific SMTP accounts, which was introduced in 7.x, but if I understand correctly, you are using host SMTP configuration.
It looks like Newsletter does not properly call SendMail to use secure connection, I haven't had a look at the code for quite some while, it might be a bug, not passing the "secure" bit properly. Unfortunately, the only solutions are a core fix or using a 3rd party module/service, sorry.
