Enewsletter pluggin cant get outgoing email test to work

Hi Guys,

I cant get Enewletter plugin to work - having problems with outgoing email settings.

I deactivated Postman SMTP and I got the test to work in Enewsletter once, then tried again and didn't work. I have now reactivated Postman SMTP because it is vital for my email messages.

I desperately need Enewsletter to work so that my new subscribers can get their welcome newsletter.

Hoping you can urgently assist.
