I got an error msg like this when sending emails:

command parameter not implemented. the server response was authenticate first (#5.5.0)

But this error message is not coming in working time it comes only after 7pm.

Answer 1

Your server would be configured to allow mails only during working hours.
This is a common setting on a lot of smtp server(Usually done to prevent misuse of an SMTP server).

Contact your network admin to resolve it.
