SUMMARY
If UNKN commands are appearing in the logs, this article explains any issues and ways the command can be reported.
DETAIL
If the MailEnable SMTP logs display the command error of UNKN and a client at this time has sent the ehlo verb, the client should then submit the HELO verb if the EHLO fails. There is no problem here, the UNKN command will then alert the client to try the HELO.
MORE INFORMATION
The system will recover from the UNKN command.
