Thanks, we are indeed using a large hosting provider.
And, so... I called to inquire about changing those settings, and basically was told we had no access and that changing those settings on a shared server was not an option.
Essentially, any email sent through PHP is going to have a major delay due to authentication.
But it got me thinking... Form Tools does have the Swift Mailer module which, in theory, is supposed to "override the default mail() functionality" and use SMTP instead, right?
So I've been bashing my head at various configurations for hours. I went into our site cPanel and created some new email accounts. I've been trying variations of logins with Swift Mailer, and I can get a fast email to go through when testing within the module.
But... when I go to test the responsiveness of the automated emails within an actual Form Tools form, the lag returns. And form submissions themselves continue to go through painfully slow.
I did find an email authentication page in cPanel that I do have access to, and have been messing with the settings for:
DKIM ("DKIM is a means of verifying incoming email. It ensures that incoming messages are unmodified and are from the sender from whom they claim to be. This feature works to prevent incoming spam messages.") and SPF ("The SPF system allows you to specify servers and IP addresses that are authorized to send mail from your domain(s). This feature works to prevent outgoing spam messages.")
Not sure if it will help anything. According to the help page, "as these are DNS settings, they may take up to 24 hours or more before they begin to take effect."
Thinking I may step away for a day or two.
Side note, I don't suppose the Swift Mailer upgrade discussion on this same forum might be an option?
