I have been using thenewsletter plugin with great success till the latest update. since the update was done all mails that have been sent out have been bouncing back as undeliverable, also I am now unable to set up the smtp in configuration, I keep getting this error: “SMTP connect() failed”
Hi, the connection failed could be a problem of your provider blocking it. Try to open a ticket. You can even try to use an SMTP plugin just to see if something changes, but our SMTP implementation is standard, it should work.
The connection failed sounds to be a network problem.
