Well another 176 emails in the mail queue. Similar amount to where we saw the forum slowed down and get faster once flushed.
But why are there stuck in the queue.
Mailcatch.com can be handy, you can sign up to places, activate your email address, and then dispose of that email address. So it's just a free temporary email address.
We are getting a lot of spam users signing up with that sort of email account and not activating. They not even registers the email account on mailcatch.com by the looks of it. So no email box to receive the email, mailcatch is neither accepting the email or bouncing back with an error, so the email keeps trying to be delivered. Causing unnecessary traffic.
So my action. If you sign up to the website with an @mailcatch.com email address it will be refused along with @mail.ru
