Help: SMTP Protocol Returned a Permanent Error 501 Syntax error

Hello,when I want to send a mail to Internet, i have this message : “Error transferring to smtp.xxxx.FR; SMTP Protocol Returned a Permanent Error 501 Syntax error”

I am testing my new server which will be alone in my domain to send mail to Internet.

I reviewed all parameters and I don’ t understand why this error.

Somebody knows what is this “Permanent Error 501 Syntax error” ?

thank you for your help

Subject: I found the error

because I have read in forum V5 somebody tell for notes.ini variable SMTPDEBUGCLIENT=3 , I put it and after I have seen it was the notes domain separator which was rejected by destinatary host. My separator was % and I changed it by a point and it is good !!
