First after making a few of changes to server.tab on the spare system
it gave relay denied at 'RCPT TO:' same as other system had done.
Other than 'cosmetic' changes to get configs closer, eg. Maxerrors
increased from "2" to "3", only ones I think made the difference are:
"SmtpNoSSLAuths" "1"
"EnableCTRL-TLS" "0"
"EnableSMTP-TLS" "0"
"EnablePOP3-TLS" "0"
Only guessing how to proceed with above code but looks as if
something bad happened.
