Yes, I have read through all previous posts on this
My problem is that emails to reviewers and copyeditors are not being received by them. When sending an email to myself through OJS that works. I understand that there is a bug related to this but I cannot upgrade at the moment. Is there any way of getting this fixed? My hosting's email log shows some emails going through. It appears that a lot of emails are being send out to spam accounts such as 'firstname.lastname@example.org
SMTP error from remote mail server after RCPT TO:: host alt4.gmail-smtp-in.l.google.com [220.127.116.11]: 450-4.2.1 The user you are trying to contact is receiving mail too quickly.\n450-4.2.1 Please resend your message'
What can I do to stop this?
