Greetings,
Our server is sending validation request emails like the one below to people/bots trying to subscribe:
Subject: Validate Your Account
To: vfrcbvbfysx vfrcbvbfysx
You have created an account with our journal, but before you can start using it, you need to validate your email account. To do this, simply follow the link below:

Thank you
In return, we are getting several of these messages a day:
Delivery incomplete
There was a temporary problem while delivering your message to someuser@gmail.com. Gmail will retry for 46 more hours. You’ll be notified if the delivery fails permanently.
450 4.2.1 The user you are trying to contact is receiving mail at a rate that prevents additional messages from being delivered. Please resend your message at a later time. If the user is able to receive mail at that time, your message will be delivered. For more information, please visit https://support.google.com/mail/?p=ReceivingRate f13sor2732670qke.115 - gsmtp
I believe the message is because the bots that are trying to subscribe have overflown Gmail mailboxes and what not, but the question then is - can we turn on/off something in OJS that will save us from getting these messages?
