I am having problems transferring SMTP email to a particular domain ---- If a single piece of email is sent, no problem. If multiple emails are sent, I end up getting a “remote system no longer responding” and “transmit error received from remote server” messages when I tell router sho all.
I have gone so far as setting max concurrent to 1. If I tell router quit and reload the router, I can manager to get another email out.
Have not had any firewall / network changes.
Any ideas???
