Connection could not be established with host

[Papapooch]

Well I finally found the Campaign Log data I needed by running a SQL query against the MW database.
It appears that for a Send of just 8 email addresses...all my own active email addresses I use for testing...the Connection to Host failed for 5 of the 8 email addresses. Wow!

This was during testing of the MailRelay server I attached to MailWizz as SMTP.
For such a small list why does the Host server have to be connected once for every single email??

I have attached the CSV I pulled from the MW Database.

NO I guess I will have to ZIP it as the Forum doesn't accept CSV files.

This is how smtp works by default, keeping connections active is a difficult thing. You could enable the number of emails you allow per connection from the delivery server settings, but i advise you let it to be just one as is now.
Also, next version of mailwizz will retry sending for failed emails, so it's just a matter of time
