[esmaeil63]

hello 

i am trying to send an email from my mobile to my laptop but failed, noting that it is in a different language. The original language of my mobile and laptop was Arabic/English, recently i added Bengali language to both in order to send the email ( in Bengali language) to my laptop from the mobile, but it gives me this message(554: Message not accepted due to failed RFC compliance [006]), what shall i do to receive the email in Bengali language.

Hi Esmaeil,

The error "554: Message not accepted due to failed RFC compliance [006]" indicates that email server did not accept the email. We would have to verify or narrow down to understand what changes resulted in the email being non-compliant.
Please check if "From," "To," "Subject," and other headers are in correct format.
