Didn't know about that, @Gus , but you should be using port 587 anyway - and that appears to get round the problem because I haven't seen that warning.

Sods law it works again, thinking I might have trigger the failed login as I had capslock on during 3 attempts.  Now to find the error log file

Fix

@jab1 is correct, port 587 should be used by an email submission client.  Port 25 is for MX to MX message relay.

Also if using encryption, port 587 should use STARTTLS.

@Gus not sure whether you're aware, but you can also use encrypted connections to receive email now.

For POP3 use SSL/TLS on port 995

For IMAP use SSL/TLS on port 993
