Hello,
I have having an issue where this plugin is not sending any emails on my sub-domain sites. When sending a test email, it gives the error:
"SMTP Error: The following recipients failed: myemail@email.com
SMTP server error: Temporary local problem - please try later"
I am using a Multi-site and have tried activating the plugin both at the top level, as well as on each individual site.
I found the the site on the base URL (mysite.com.au) works perfectly, but as soon as I try use it on one of the sub-domains (subdomain.mysite.com.au) it throws the above error.
Is the plugin created to work on multi-site websites?
Thanks
