Thanks for this plugin.
The emails send fine as long as I use the(php) option, but that option doesn't seem to hold up when a lot of traffic needs to go out from the site (I have forms on my site and users need to receive confirmation emails).
I would like to use the smtp but I cannot for the life of me get it to connect and send a successful test email. I've tried multiple gmail accounts, a hotmail account, and an outlook account. I have used every combination of smtp host & port for those respective mail servers/providers that I can find anywhere on the internet.
Any help would be appreciated, as it seems the smtp configuration would allow my forms to be more reliable for participants!
Many thanks.
