220 smtp6-g21.free.fr ESMTP Postfix
250-smtp6-g21.free.fr
250-PIPELINING
250-SIZE 78643200
250-VRFY
250-ETRN

250-ENHANCEDSTATUSCODES

So PLAIN and LOGIN methods are authorized by free and you should be able to connect by these ways which are used by the firmware
Note start TLS should not be activated and you have to let empty the DDNS field
